Abstract:
This dissertation describes the use of a number of seismic techniques to probe further the crustal and uppermost mantle shear velocity structure of the collision zone and the undeformed Indian shield to the south. A study of Rayleigh wave fundamental mode group velocity dispersion curves for 4054 receiver-source paths across India, Tibet and surrounding regions is used to obtain high-resolution group velocity maps between 10s and 70s. The dataset provides a higher frequency content than previous global studies and, with the inclusion of long paths up to ~5000km, bridges the gap between regional and global studies. This provides better constraints on whole crustal structure. Higher frequency P to S receiver functions are used to resolve the position of the major interface beneath seismic stations across the region; most importantly the crust-mantle boundary. Joint inversion of receiver function data and group velocity dispersion data limits the non-uniqueness inherent in receiver function inversion which is highly sensitive to a depth-velocity trade-off. The receiver function study is divided into two parts, defined by geographical area. Firstly, data from a number of broadband stations deployed over the course of this research in West Bengal and Sikkim are analysed alongside data from the INDEPTHII deployment which provides a northwards extension of the profile into Tibet. Data from previous experiments in nearby Nepal and Bhutan are studied in order to give a more complete picture of the crustal structure of this region of the Himalayas. Secondly, receiver function data for a large number of stations across the South Indian shield are revisited to provide an improved and coherent picture of variations in crustal thickness across the different geological terrains. Finally, dispersion curves extracted from the series of group velocity maps produced for the region are inverted for shear velocity structure.

Full text
Abstract:
The kinematics of the Turkish-Iranian Plateau are studied using information from the focal mechanisms of earthquakes, observations of the geomorphology associated with active faulting, and published GPS measurements. Combining these sources of data makes it possible to examine how the velocity field is accommodated by active faulting. A band of previously unrecognised oblique normal faults is described, rotations about vertical axes are shown to be occurring in the northern plateau, and the age of initiation of the current configuration of faulting is estimated. The dynamics of continental deformation are then considered, in a series of studies of parts of the India-Asia collision zone. The observed surface velocities are found to be consistent with viscous flow in response to gravitational body forces, and the importance of the lower boundary condition is discussed. Deformation maps for common rock-forming minerals show modelling results to be consistent with laboratory measurements of the rheology of minerals. Gravitationally-driven flow provides an explanation for the occurrence of normal-faulting earthquakes in the southern Tibetan Plateau, and for the formation of the Eastern Himalayan Syntaxis. The final part of this thesis combines the two approaches described above. The kinematics of the southeastern margin of the Tibetan Plateau are examined in detail, and numerical modelling is used to suggest the origins of the observed velocity field. It is found that the long-wavelength deformation is driven by pressure gradients in the crust resulting from topographic slopes, and that horizontal surface velocities alone cannot be used to distinguish between two possible modes of deformation.

Abstract:
This dissertation consists of three manuscripts that will be submitted for publication. All three of these examine various aspects of the evolution of the India-Asia suture zone in southern Tibet after the India-Asia collision. Continent-continent collision is one of the basic tectonic plate boundary types, has occurred repeatedly throughout geologic history, and represents one of the principle mechanisms responsible for the formation of high elevation plateaus and orogens. Uplift within these zones has also drastically changed the earth's climate and atmospheric circulation, and erosion from continental collision has resulted in some of the thickest accumulations of sediment in the world (Curray, 1991; Einsele et al., 1996). However, despite the global significance of continental collision, much of the fundamental geodynamic and geologic processes governing these events remain enigmatic. This is the result of several factors. First and foremost, intense deformation and uplift of rocks, often from mid crustal levels, over very short periods of time (Hodges and Silverberg, 1988; Seward and Burg, 2008; Zeitler et al., 2014) results in the erosive removal of much of the geologic record of a collision zone. Second, because the best modern example of continental collision is the Tibet-Himalayan system, the study of continental collision in general has been hampered by high elevations, remoteness, difficult working conditions, and political unrest. The work presented here represents a step toward better understanding the geology, geologic history, and geodynamic evolution of the Tibetan Plateau, the Himalaya, and the India-Asia collision. This has been accomplished through study of two of the post-collisional sedimentary basins which formed near or within the India-Asia suture zone. Appendix A addresses the structure, sedimentology, age, and provenance of the Liuqu Conglomerate. The key conclusions of this section are: 1) The Liuqu Conglomerate was deposited in north flowing, stream dominated alluvial fans. These were located situated in a wedge-top position within a system of north verging thrust faults likely associated with the Great Counter Thrust, and sediment was accommodated via burial beneath thrust structures. 2) The age of the Liuqu Conglomerate has been refined to ~20 Ma based on detrital zircon U-Pb and fission track dating, ⁴⁰Ar/³⁹Ar dating of biotite from a cross-cutting dike, re-analysis of previously published pollen data, regional structural considerations, and oxygen isotope composition of paleosol carbonates. 3) Sand-sized and finer-grained sediment eroded from the southern margin of Asia prior to collision was transported southwards across the Xigaze forearc basin, deposited within the subduction trench, and then accreted within the subduction complex mélange. After collision, this sediment was eroded from the mélange and shed northward into the India-Asia suture zone. Appendix B focuses on the abundant paleosols preserved within the Liuqu Conglomerate. This study uses major element geochemistry of these paleosols and stable isotope analyses of paleosol carbonates to constrain the degree and type of chemical weathering, and thus the paleoclimate and paleoelevation, of the Liuqu Conglomerate. The key conclusions of this paper are: 1) at ~20 Ma, the India-Asia suture zone experienced warm and wet conditions that promoted intense chemical weathering of soils exposed in the inactive portions of alluvial fans. Paleorainfall is estimated at ~1500 mm/yr, and weathering intensity was similar to soils formed in the Neogene Siwalik Group of India, Nepal, and Pakistan, which formed under wet, semitropical, and low elevation conditions. 2) The India-Asia suture zone experienced these conditions at ~20 Ma despite extensive deformation and crustal thickening which has been documented within the Tethyan Himalayan and Himalayan thrust belts. This crustal thickening should have resulted in the (surface) uplift of the entire India-Asia collision zone, and there is evidence that at least some portion of the Himalayan crest was at or near modern elevations by ~17 Ma. Our results require either that the Tethyan Himalaya and India-Asia suture zone were not uplifted despite as much as 40 million years of intense crustal shortening or that these regions attained high elevation prior to ~20 Ma, and then lost elevation around this time before being immediately re-uplifted. The viability of these two scenarios cannot be explicitly tested with the data presented in this chapter; however, based on the data presented in Appendix C, I strongly favor the second scenario. Appendix C focuses on the Kailas Formation, exposed ~20 km north of the Liuqu Conglomerate within the India-Asia suture zone. The Kailas Formation is exposed along ~1300 km of the India-Asia suture zone. For this study, I present new sedimentologic, provenance, and geochronologic data for the Kailas Formation. Key findings of this study are that 1) the Kailas Formation is younger in the center of the suture zone, near 90°E, and becomes progressively older to the west; preliminary data suggest that these rocks are older to the east as well, but additional age constraints are required. 2) The pattern of sedimentation documented for the Kailas Formation is nearly identical to the spatio-temporal pattern of adakitic and ultrapotassic rocks in southern Tibet. These rocks have been attributed to rollback and breakoff of the Indian continental slab. Sedimentation within the Kailas basin has also been attributed to rollback of the Indian slab (DeCelles et al. 2011), and this idea is corroborated by the agreement of the sedimentary and magmatic records. 3) This presents an interesting possibility for explaining the existence of low elevations within the India-Asia suture zone at ~20 Ma, as documented in Appendix B. High elevation topography produced by crustal shortening and thickening likely remained intact until slab rollback and breakoff started around 30 Ma and caused the India-Asia suture zone to experience large scale extension and subsidence. The Kailas Formation was deposited in the resulting basin, which opened first in the west, and propagated eastward. After slab breakoff occurred, contractional deformation would have resumed, and the area would have been quickly uplifted to its modern elevations.

Abstract:
The Lopu Range, located similar to 600km west of Lhasa, exposes a continental high-pressure metamorphic complex beneath India-Asia (Yarlung) suture zone assemblages. Geologic mapping, 14 detrital U-Pb zircon (n=1895 ages), 11 igneous U-Pb zircon, and nine zircon (U-Th)/He samples reveal the structure, age, provenance, and time-temperature histories of Lopu Range rocks. A hornblende-plagioclase-epidote paragneiss block in ophiolitic melange, deposited during Middle Jurassic time, records Late Jurassic or Early Cretaceous subduction initiation followed by Early Cretaceous fore-arc extension. A depositional contact between fore-arc strata (maximum depositional age 971Ma) and ophiolitic melange indicates that the ophiolites were in a suprasubduction zone position prior to Late Cretaceous time. Five Gangdese arc granitoids that intrude subduction-accretion melange yield U-Pb ages between 49 and 37Ma, recording Eocene southward trench migration after collision initiation. The south dipping Great Counter Thrust system cuts older suture zone structures, placing fore-arc strata on the Kailas Formation, and sedimentary-matrix melange on fore-arc strata during early Miocene time. The north-south, range-bounding Lopukangri and Rujiao faults comprise a horst that cuts the Great Counter Thrust system, recording the early Miocene (similar to 16Ma) transition from north-south contraction to orogen-parallel (E-W) extension. Five early Miocene (17-15Ma) U-Pb ages from leucogranite dikes and plutons record crustal melting during extension onset. Seven zircon (U-Th)/He ages from the horst block record 12-6Ma tectonic exhumation. JurassicEocene Yarlung suture zone tectonics, characterized by alternating episodes of contraction and extension, can be explained by cycles of slab rollback, breakoff, and shallow underthrustingsuggesting that subduction dynamics controlled deformation.

Abstract:
The characteristic remanent magnetization (ChRM) isolated from Paleogene carbonate rocks of the Zongpu Formation in Gamba (28.3 degrees N, 88.5 degrees(E) of southern Tibet has previously been interpreted to be primary. These data are pertinent for estimating the width of Greater India and dating the initiation of India-Asia collision. We have reanalyzed the published ChRM directions and completed thorough rock magnetic tests and petrographic observations on specimens collected throughout the previously investigated sections. Negative nonparametric fold tests demonstrate that the ChRM has a synfolding or postfolding origin. Rock magnetic analyses reveal that the dominant magnetic carrier is magnetite. "Wasp-waisted" hysteresis loops, suppressed Verwey transitions, high frequency-dependent in-phase magnetic susceptibility, and evidence that > 70% of the ferrimagnetic material is superparamagnetic at room temperature are consistent with the rock-magnetic fingerprint of remagnetized carbonate rocks. Scanning electron microscopy observations and energy-dispersive X-ray spectrometry analysis confirm that magnetite grains are authigenic. In summary, the carbonate rocks of the Zongpu Formation in Gamba have been chemically remagnetized. Thus, the early Paleogene latitude of the Tibetan Himalaya and size of Greater India have yet to be determined and the initiation of collision cannot yet be precisely dated by paleomagnetism. If collision began at 59 +/- 1 Ma at similar to 19 degrees N, as suggested by sedimentary records and paleomagnetic data from the Lhasa terrane, then a huge Greater India, as large as similar to 3500-3800 km, is required in the early Paleogene. This size, in sharp contrast to the few hundred kilometers estimated for the Early Cretaceous, implies an ever greater need for extension within Greater India during the Cretaceous.

Abstract:
Deux questions scientifiques critiques sont adressées dans cette thèse présentées comme suit. ( 1 ) L’évolution mésozoïque du bassin d’avant-pays dans les piémonts nord et sud du Tian Shan. ( 2 ) L’évolution au Cénozoïque précoce du soulèvement du Tian Shan. Dans le chapitre 1, l'évolution du nord Tian Shan est étudiée par datation U/Pb (LA- ICP-MS) de zircons détritiques sur 14 échantillons de grès d'une série continue d’âge fin Paléozoïque à Quaternaire dans la marge sud du bassin de Junggar (région de Manasi). Dans le chapitre 2, l'évolution encore mal contrainte entre le Mésozoïque et le début du Cénozoïque de la marge sud-ouest du Tian Shan est étudiée en utilisant les datations U/Pb ( LA- ICP-MS ) sur zircons détritiques et les traces de fission sur apatites détritiques. Dans le chapitre 3, nous présentons une étude magnétostratigraphique détaillée de la zone Ulugqat au sud-ouest du Tian Shan, dans le but d'améliorer la compréhension de son soulèvement et de l'histoire de la déformation de la région au cours du Cénozoïque. Ce travail à permis de montrer que l'érosion du paléo-Tian Shan commencée au Trias moyen s’est traduite par le pénéplanation générale au Mésozoïque du Tian Shan qui était dominé par un système de drainage large pendant une longue période de quiescence tectonique. Le piémont nord du Tian Shan était caractérisé par un bassin en subsidence thermique post- extensive avec peu d'activité tectonique, et le piémont sud a également connu un aplanissement général de la topographie. Au cours du début du Jurassique, du Crétacé inférieur et du Crétacé supérieur, trois inversions tectoniques mineures sont identifiées avec des ajustements du bassin d’avant-pays du Tian Shan. Ces inversions peuvent correspondre respectivement à l’accrétion des terrains Cimmérien, de Lhassa, et du Kohistan-Dras à la limite sud de la plaque eurasienne. Les données U-Pb sur zircons détritiques et les données traces de fission sur apatite indiquent une première réorganisation du bassin à la fin du Crétacé – début du tertiaire, contemporaine d’une réactivation de l’érosion le long du piémont sud du Tian Shan. Nous avons interprété cette réactivation fin Crétacé – début Paléogène du Tian Shan sud à la réponse initiale des effets lointains de la collision Inde-Eurasie. Pendant le reste du Cénozoïque, la principale réactivation du Tian Shan est initiée fin Oligocène – début Miocène. Cela est attesté dans le piémont nord du Tian Shan par nos données U-Pb sur zircons détritiques et dans le piémont sud du Tian Shan par les données traces de fission sur apatite suggérant des chevauchements entre 18 et 16 Ma, par les résultats magnétostratigraphiques révélant une importante lacune de sédimentation oligocène ainsi que l’augmentation des taux d’accumulation à ~ 18.5 Ma
Two critical scientific issues are adressed in the présent thesis as follows. (1) Mesozoic basin-range relationship in the northern and southern piedmonts of the Tian Shan. (2) Spatio-temporal differences in the Early Cenozoic uplift of the Tian Shan. In chapter 1, the évolution of the northern Tian Shan is investigated through U/Pb (LA-ICP-MS) dating of detrital zircons from 14 sandstone samples from a continuous series ranging in age from latest Palaeozoic to Quaternary in the southern margin of the Junggar Basin (Manasi area). In chapter 2, the still poorly constrained Mezosoic to early Cenozoic evolution of the southwestern Tian Shan piedmont is investigated using U/Pb (LA-ICP-MS) dating of detrital zircons and fission track analysis on detrital apatites. In chapter 3, we present a detailed magnetostratigraphic study from the Ulugqat area in piedmont of the Southwest Tian Shan, in order to improve understanding of the uplift and deformation history of the Southwest Tian Shan during the Cenozoic. This work enabled to show that erosion of the Paleo-Tian Shan initiated in the Middle Triassic results in the general peneplanation of the Mesozoic Tian Shan dominated by a wide drainage system and long-lasting tectonic quiescence. The northern piedmont of the Tian Shan was characterized by a post-extensional thermally subsiding basin without much tectonic activity, and the southern piedmont also experienced a general flattening of topography. During the Early Jurassic, Early Cretaceous and Late Cretaceous, three identified minor tectonic inversions and adjustments of basin-range pattern in the Tian Shan, may potentially correspond respectively to the accretions of Cimmerian, Lhasa, and Kohistan-Dras in the southern margin of the Eurasian plate. Detrital zircon U-Pb and apatite fission-track data indicate an initial late Cretaceous – Early Tertiary basin reorganization and coeval renewed erosion along the southern Tian Shan piedmont. We interpreted this late Cretacesou to Paleogene activity in STS as the initial response of the distant effects of India-Eurasia collision as previously argued. During the Late Cenozoic, the major reactivation of the Tian Shan initiated around the Late Oligocene-Early Miocene times. This is evidenced mainly from the detrital zircon U-Pb geochronology in the northern piedmont of the Tian Shan, the apatite fission-track data suggesting a possible activation of the Talas Fergana Fault between 18 and 16 Ma, the major Oligocene depositional hiatus and conspicuous increase in accumulation rates at ~ 18.5 Ma revealed by the magnetostratigraphic results in the southern piedmont of the Tian Shan

Abstract:
This dissertation research addresses the tectonism of continental crust during ocean basin closure, suturing between continental landmasses, and collisional orogenesis. The new data and insights presented here were gathered through localized geologic investigations of the Tibetan Plateau of central Asia. This area of central Asia is an ideal location to study these fundamental tectonic processes because it has been the locus of numerous Tethyan ocean basins and terminal collisions between continents during Phanerozoic accretion of Gondwana-derived landmasses onto the southern margin of Eurasia. In this work, I propose, in many orogens, that high-pressure (HP) metamorphism of continental rocks may mark the early stages of the suturing process between continental landmasses rather than the culmination of suturing. This insight has been acquired from a geologic-, geochronologic-, and thermochronologic-based investigation of the HP-near ultrahigh-pressure bearing Triassic metasedimentary metamorphic belt in central Tibet. This work shows near synchronous continent-continent collisions between landmass adjacent to the Paleo-Tethys ocean prior to its final closure in Late Triassic time. In addition, this work shows that Mediterranean-style tectonics may be more widespread during accretionary tectonics than previously thought. A comparison between the distribution of the HP bearing metamorphic belt, autochthonous crystalline basement, and geophysical images of Tibet suggests that a Mesozoic tectonic feature may be controlling the structure and distribution of melt within the middle crust of the Tibetan Plateau. This concept underscores the importance of inherited tectonic frameworks on the evolution of orogenic plateaus. Work in southwest Tibet, along the India-Asia suture zone, highlights the complex behavior of continental crust during collisional orogenesis. This work identifies previously undocumented magmatism, crustal antexis, and high-grade metamorphism along the India-Asia suture. In this work I attribute these observations to the initial interactions between Indian, Asian, and subducting Neo-Tethys oceanic lithosphere.

Abstract:
To understand how the Himalaya were formed it seemed logical to start at the actual zone of plate collision, the Indus suture zone. Most of this collision zone runs across southern Tibet, which in the 1970s was almost impossible to travel through. Following Mao Tse-tung’s Red Army’s invasion and occupation of Tibet in October 1950, that region had remained firmly closed to all foreigners. In the western Himalaya the Indus suture zone runs right across the northernmost province of Ladakh. Ladakh used to be a part of southwestern Tibet before the British annexed it during the Raj. Leh, the ancient capital of Ladakh at 3,500 metres in the Indus Valley, was the final outpost of British India before the great trans-Himalayan barrier of the Karakoram Range. Only the Nubra Valley and the Tangtse Valley north of Leh were beyond the Indus, and these valleys led directly up to the desolate high plateau of Tibet. Leh was a major caravan route and a crossroads of high Asia, with double-humped dromedary camel caravans coming south from the Silk Route towns of Yarkhand and Khotan; Kashmiris and Baltis came from the west and Indian traders from the Hindu regions of Himachal and Chamba to the south. Ladakh, Zanskar, and Zangla were three ancient Himalayan kingdoms ruled by a Giapo, or King, each from a palace that resembled a small version of the Potala Palace in Lhasa. In 1978, when we were climbing in the mountains of Kulu, I had looked from our high summits across to the desert mountains of Lahoul and Zanskar, north of the main Himalayan watershed. Here, in the ancient Buddhist kingdoms of Zanskar and Ladakh lay wave upon wave of unexplored and unclimbed mountains. They lay north of the monsoon limits and in the rain shadow of the main Himalaya, so the vegetation was sparse, and the geology was laid bare. Flying north from Delhi, or east from Kashmir into Leh, the views were simply mesmerizing.

Abstract:
From the geological mapping, structural, and metamorphic investigations along the main Himalayan Range from Zanskar in the west through the Himachal Pradesh and Kumaon regions of India and along the whole of Nepal to Sikkim, a similar story was emerging. The overall structure and distribution of metamorphic rocks and granites was remarkably similar from one geological profile to the next. The Lesser Himalaya, above the Main Boundary Thrust was composed of generally older sedimentary and igneous rocks, unaffected by the young Tertiary metamorphism. Travelling north towards the high peaks, the inverted metamorphism along the Main Central Thrust marked the lower boundary of the Tertiary metamorphic rocks formed as a result of the India–Asia collision. The large Himalayan granites, many forming the highest peaks, lay towards the upper boundary of the ‘Greater Himalayan sequence’. North of this, the sedimentary rocks of the Tethyan Himalaya crop out above the low-angle normal fault, the South Tibetan Detachment. The northern ranges of the Himalaya comprise the sedimentary rocks of the northern margin of India. The two corner regions of the Himalaya, however, appeared to be somewhat different. The Indian plate has two major syntaxes, where the structural grain of the mountains swings around through ninety degrees: the western syntaxis, centred on the mountain of Nanga Parbat in Pakistan, and the eastern syntaxis, centred on the mountain of Namche Barwa in south-east Tibet. Nanga Parbat (8,125 m) is a huge mountain massif at the north-western end of the great Himalayan chain. It is most prominent seen from the Indus Valley and the hills of Kohistan to the west, where it seems to stand in glorious isolation, ringed by the deep gorges carved by the Indus and Astor Rivers, before the great wall of snowy peaks forming the Karakoram to the north.

Abstract:
As continents moved from Pangea to their present positions, they experienced more than 100 million years of geologic history. Compressive and extensional stresses generated by collision with continental and oceanic plates formed mountain belts, zones of rifting and strike-slip faulting, and magmatism in all of these environments. In this chapter we can only provide capsule summaries of this history for each of the various continents, but many of their salient features have been discussed as examples of tectonic processes in earlier chapters. The final section analyzes the breakup of Pangea as part of the latest cycle of accretion and dispersal of supercontinents. Because it involves continuation of this cycle into the future, it is necessarily very speculative. Figure 10.1 shows approximate patterns of movement of each continent from its position in Pangea to the present. The dominant feature of this pattern is northward movement of all continents except Antarctica, which has remained over the South Pole for more than 250 million years. Shortly after geologists recognized the concept of continental drift, this movement was referred to by the German word “Polflucht” (flight from the pole) because all of the continents were seen to be fleeing from the South Pole. The only continent that did not simply move northward was Eurasia, which essentially rotated clockwise and changed its orientation from north–south to east–west. Comparison of fig. 10.1 with fig. 8.12a (locations of continents shortly before the assembly of Gondwana) shows that the net effect of the last 580 million years of earth history has been a transfer of most continental crust from the southern hemisphere to the northern hemisphere. Accretion and compression against the southern margin of Eurasia constructed a series of mountain belts from the Pyrenees in the west to the numerous ranges of Southeast Asia in the east. This collision generated extensional and transtensional forces that opened rifts and pull-apart basins. Tectonic loading created foreland basins with sediment thicknesses of several kilometers. Opposite the area where the collision of India caused the most intense compression, the extensional basins are interspersed with mountain ranges that were lifted up intracontinentally. We divide the discussion of Eurasia into a section where compression dominates to the south (present orientation) of the former margin of Pangea and a section that describes processes within the landmass to the north.

Abstract:
Geographically, Indochina consists of the South East Asian countries Thailand, Laos, Cambodia, and Vietnam. Geologically, Indochina includes all the land bounded by two very large-scale strike-slip faults—the Sagaing fault, which runs down the length of Burma, and the Red River fault, which extends more than 1,100 kilometres from the south-eastern corner of Tibet south-east through Yunnan and North Vietnam to Hanoi and the Gulf of Tonkin. Both faults are active, and show that Indochina is moving south-east relative to both the Burma micro-plate to the west and the South China block north of the Red River fault. The unresolved questions were how far Indochina was extruding away from the India–Asia collision zone and when these faults became active. The eastern margin of the Indian plate lies along the Burma–Andaman– Sumatra–Java trench, where the Indian oceanic plate is subducting beneath the great island arc chain of Indonesia. Behind the island arc, a new oceanic basin has formed in the past 5 million years, with basaltic ocean crust forming along a small active spreading centre in the Andaman Sea. The northern extension of the Andaman trench extends into the Arakan-Yoma Hills of western Burma, but the nature and location of the transition from oceanic lithosphere beneath the Bay of Bengal to continental lithosphere in Burma is poorly known. In the south of Burma, where the Irrawaddy River drains into the Andaman Sea, a vast delta has built up with over 10 kilometres’ thickness of sediments eroded off the mountains of Burma. The Sagaing fault continues offshore and is connected to the young oceanic spreading centre in the Andaman Sea. In northern Burma the fault passes close to the cities of Meiktyla and Mandalay and then splays into several branches that terminate in the Jade belt and other mountain ranges that ripple northwards towards the eastern Himalayan syntaxis. Burma is a hauntingly beautiful country of serene landscapes, golden pagodas, green rice fields, range upon range of distant hills, teak forests, and wide muddy rivers. It is also a land of great mineral riches.
