Abstract:

AbstractFollowing a palaeoclimatic outline of the Late Quaternary, the paper reviews the periglacial and slope processes which have most effect on engineering works, particulary with regard to relic forms of such features in Britain. The first topics covered are; frost heave and thaw consolidation, thermokarst and periglacial mass movements, with particular attention to periglacial solifluction and slope development. Ground water discharge features, comprising pingos, anomalous depressions in the London Basin and perforated clay feather edges, are then discussed, as are superficial valley disturbances in various geological settings. The paper concludes by exploring theoretical and geological approaches to the determination of the former depths of permafrost in Britain.

Abstract:

Climate has been proposed conventionally as the primary factor that determines periglacial river activity (aggradation) and pattern (braided). This concept does not explain the rich diversity in river patterns and morphological processes in both the present and past periglacial environments: besides braided rivers and sandur, meandering, anabranching, transitional and deltaic rivers also occur. A first attempt is made to combine past and present periglacial river types with regard to their morphology, processes and environments. The processes that control river energy and morphology are discussed especially for periglacial conditions. This approach permits an assessment of the responses of periglacial rivers to climatic conditions and the modulation of the responses due to changes in the basin properties. Examples drawn from palaeo- and present-day periglacial rivers and environments demonstrate that there is no unique type of periglacial river but rather an azonal fluvial system with a number of periglacial variants.

Abstract:

Abstract. An increasing number of studies point to a strong periglacial control on bedrock erosion in mountain landscapes. Periglacial processes have also been suggested to control the formation of block-fields on high-elevation, low-relief surfaces (summit flats) found in many alpine landscapes. However, to which degree periglacial processes took part in accelerating global erosion rates in response to Late Cenozoic cooling still remains as an unanswered question. In this study, we present a landscape evolution model that incorporates two periglacial processes; frost cracking and frost creep, which both depend on the mean annual temperature (MAT) and sediment thickness. The model experiments allow us to time-integrate the contribution of periglacial processes to mountain topography over million-year time scales. It is a robust result of our experiments that periglacial frost activity leads to the formation of smooth summit flats at elevations dominated by cold climatic conditions through time periods of millions of years. Furthermore, a simplistic scaling of temperatures to δ18O values through the late-Cenozoic indicates that many of the highest summit flats in mid- to high-latitude mountain ranges can have formed prior to the Quaternary. The model experiments also suggest that cooling in the Quaternary accelerated periglacial erosion by expanding the areas affected by periglacial erosion significantly. A computational experiment combining glacial and periglacial erosion furthermore suggests that landscape modifications associated with glacial activity may increase the long-term average efficiency of the frost-related processes.

Abstract:

The article is focused on issuing of the permanent stabilisation of geodetic points in the periglacial environment. Periglacial environment of ice-free areas of northern James Ross Island is characterised by specific geomorphological processes connected with freezing and thawing and mass movement processes in the superficial part of the ground. Variable intensity of periglacial processes creates main limitations for traditional methods of permanent geodetic point’s stabilisation. This article describes periglacial processes with regards to the traditional stabilisation methods and suggests alternative solutions, which were practically applied and verified on the ice-free area of Ulu Peninsula, northern James Ross Island.

Abstract:

AbstractRecent accounts suggest that periglacial processes are unimportant for large-scale landscape evolution and that true large-scale periglacial landscapes are rare or non-existent. The lack of a large-scale topographical fingerprint due to periglacial processes may be considered of little relevance, as linear process–landscape development relationships rarely can be substantiated. Instead, periglacial landscapes may be classified in terms of specific landform associations. We propose “cryo-conditioning”, defined as the interaction of cryotic surface and subsurface thermal regimes and geomorphic processes, as an overarching concept linking landform and landscape evolution in cold regions. By focusing on the controls on processes, this concept circumvents scaling problems in interpreting long-term landscape evolution derived from short-term processes. It also contributes to an unambiguous conceptualization of periglacial geomorphology. We propose that the development of several key elements in the Norwegian geomorphic landscape can be explained in terms of cryo-conditioning.

Abstract:

AbstractOne of the distinguished efforts of A.L. Washburn was to reconstruct mean annual air temperature using periglacial features as climate indicators. This paper reviews existing periglacial indicators and proposes a strategy to improve their thermal resolution based on recent periglacial process studies, with a focus on solifluction and thermal contraction cracking and associated landforms/structures. Landforms resulting from solifluction reflect both the depth subjected to freeze–thaw and the thickness of frost-susceptible soils. The thickness of a solifluction structure can be used to infer the dominant freeze–thaw regime and minimum seasonal frost depth. Ice-wedge pseudomorphs have limited potential as a climate indicator because (1) they mainly reflect extreme winter temperatures, (2) their thermal thresholds depend on the host material, and (3) they need to be distinguished from frost wedges of other origin produced under different thermal and/or material conditions. Monitoring studies of currently active ice wedges suggest that ice-wedge cracking requires a combination of low temperature and large temperature gradients in the frozen active layer. Further field monitoring of periglacial processes and their controlling factors under various climate conditions and in various materials are needed, however, to improve the resolution of periglacial paleoclimate indicators.

Abstract:

The development and products of the natural processes present in the hard rock and weak rock areas of the volcanic Putorana Plateau were studied. Intensive frost weathering causes the degradation of glacial land forms and the formation of periglacial forms. A progressive permafrost degradation occurs on valley bottoms, accompanied by alas lake origin, peat mound creation, pingo degradation and periglacial soil development.

Abstract:

The morphostructural relief of the highest parts of the central Kopaonik Mt was altered by exogenous agents, by denudation as a primary and periglacial processes as a secondary agent. Previous geomorphological studies were mostly focused on the traces of the Pleistocene glaciation, although no reliable evidence was found for this. Recent research, in the part of the mountain above 1,700 m of absolute height, points to geomorphological phenomena resulting from more recent processes within the periglacial environment. By means of geomorphological reconnaissance, analysis and mapping of the highest part of the Kopaonik mountain massif, forms of relief were studied, the ones that according to their morphology correspond to the periglacial forms and processes described in the conditions of high latitudes and high mountains. Determining the spatial coverage of the periglacial belt, especially its lower limit on Kopaonik Mt, is important for understan-ding the distribution of this climatic morphology both in Serbia and in South East Europe. The research contributes to one of the primary aims of exploring the concept of the periglacial zone, in terms of the regional distribution of its specific relief forms.

Abstract:

With global periglacial geomorphology undergoing significant advancements, it is appropriate to review the past and current status of such research in Africa. A brief historical overview of research outputs and approaches is presented for the respective African regions. Potential future quantitative periglacial research needs and approaches identified for Africa include: the examination of active periglacial processes, the identification of landforms and ground-ice forms, the potential for environmental change and the palaeoenvironmental reconstruction, and the application of periglacial studies. It is demonstrated that while periglacial geomorphology has progressed significantly in southern Africa, there has been little or no advancement elsewhere on the continent over the last two decades. None the less, on a more positive note, it is concluded that Africa has considerable potential in future global periglacial research.

Abstract:

Abstract. With accelerating climate cooling in the late Cenozoic, glacial and periglacial erosion became more widespread on the surface of the Earth. The resultant shift in erosion patterns significantly changed the large-scale morphology of many mountain ranges worldwide. Whereas the glacial fingerprint is easily distinguished by its characteristic fjords and U-shaped valleys, the periglacial fingerprint is more subtle but potentially prevails in some mid- to high-latitude landscapes. Previous models have advocated a frost-driven control on debris production at steep headwalls and glacial valley sides. Here we investigate the important role that periglacial processes also play in less steep parts of mountain landscapes. Understanding the influences of frost-driven processes in low-relief areas requires a focus on the consequences of an accreting soil mantle, which characterises such surfaces. We present a new model that quantifies two key physical processes: frost cracking and frost creep, as a function of both temperature and sediment thickness. Our results yield new insights into how climate and sediment transport properties combine to scale the intensity of periglacial processes. The thickness of the soil mantle strongly modulates the relation between climate and the intensity of mechanical weathering and sediment flux. Our results also point to an offset between the conditions that promote frost cracking and those that promote frost creep, indicating that a stable climate can provide optimal conditions for only one of those processes at a time. Finally, quantifying these relations also opens up the possibility of including periglacial processes in large-scale, long-term landscape evolution models, as demonstrated in a companion paper.

Abstract:

Although the Velebit is a low mountain situated in the moderate climate zone, there exist periglacial processes in relief modelling in its highest part. The reason for this is interdependance of geological, geomorphological, climatic, vegetational and pedological influences, but also long antropogenic and zoogenic influences. Among periglacial forms the features which originated from the activity of nival and frost processes can be singled out.

Abstract:

AbstractAlmost all areas of the UK have been affected by periglaciation during the Quaternary and, as such, relict periglacial geohazards can provide a significant technical and commercial risk for many civil engineering projects. The processes and products associated with periglaciation in the relict periglacial landscape of the UK are described in terms of their nature and distribution, the hazards they pose to engineering projects, and how they might be monitored and mitigated. A periglacial landsystems classification is applied here to show its application to the assessment of ground engineering hazards within upland and lowland periglacial geomorphological terrains. Techniques for the early identification of the susceptibility of a site to periglacial geohazards are discussed. These include the increased availability of high-resolution aerial imagery such as Google Earth, which has proved to be a valuable tool in periglacial geohazard identification when considered in conjunction with the more usual sources of desk study information such as geological, geomorphological and topographical publications. Descriptions of periglacial geohazards and how they might impact engineering works are presented, along with suggestions for possible monitoring and remediation strategies.

Abstract:

In the continental areas of Central and High Asia, periglacial landform assemblages, sediment structures and processes are mainly influenced and determined by of soil humidity during freeze–thaw cycles. These cryogenic processes result in periglacial landforms such as solifluction, earth hummocks or patterned ground. The distribution of rock glaciers as clear indicators of permafrost is additionally determined by rock fall or moraine debris composed of large boulders (e.g. of granite). Periglacial features were used to reconstruct past climatic conditions, e.g. relict involutions and ice-wedge casts provide evidence for the distribution of former permafrost, say, for the Last Glacial Maximum (LGM). Past temperatures, e.g. mean annual air temperatures, can be estimated from these periglacial features and can be compared with other proxy data, such as glacier fluctuations. Examples from late Holocene solifluction activity in the Altai, Khangai and north-eastern Tibetan Plateau show a different intensity of solifluction processes during the late Holocene and Little Ice Age due to a decrease in temperature and higher soil humidity. The distribution of past permafrost in some regions is still a matter of debate because of different interpretations of sediment structures: sometimes features described as ice-wedge casts may be caused by roots or desiccation cracks due to drying of clay rich sediments. Seismically deformed unconsolidated deposits (seismites) can also be misinterpreted as periglacial involutions. The lack of certain landform assemblages and sediment structures does not necessarily mean that the area had no permafrost. Moisture conditions can also determine the periglacial landform generation to a large degree. They can be ordered in Central Asia as follows (from highest moisture availability to lowest): solifluction; rock glacier; permafrost involutions; ice-wedge casts; sand-wedge casts.

Abstract:

AbstractThe original distribution pattern of Middle-Palaeolithic artefacts may be affected by tectonic movement, sedimentation and periglacial processes. This is e.g. the case in the coversand area of Limburg and Eastern Brabant (NL), where the occurrence of numerous finds in a SW-NE trending zone across the Roer Valley Graben is considered enigmatic. In order to elucidate the processes affecting the spatial distribution and the chance of recovery of such artefacts, we investigated a site in Nederweert. At this site, several Middle-Palaeolithic artefacts had been recovered earlier from unexpectedly shallow depths. A test pit profile and grain size analyses revealed that the shallow sediments at this site have been affected by intense, multi-phase cryoturbation, which has deformed the sand and loam layers and partially mixed them thoroughly. As a result, optically stimulated luminescence dating of these sediments yielded widely scattered single-aliquot equivalent dose distributions. Using a Finite Mixture Model (FMM), it was estimated that cryoturbation caused mixing of sediments deposited between 12 and 50 ka with sediment grains deposited between 60-150 ka. The latter material is probably the original context of the Middle-Paleolithic artefacts. Apparently, cryoturbation and potentially other periglacial processes have transported artefacts closer to the surface. Based on these results, we suggest that the occurrence of Middle-Palaeolithic artefacts is caused by (1) the tectonically-induced spatial distribution of layers of this age and (2) periglacial processes having caused migration of artefacts towards the surface. Although periglacial processes may facilitate finding Middle Palaeolithic artefacts, they may severely disturb the original context to such an extent that Middle Palaeolithic sites can no longer be identified. The results of this study form a basis for improving the Indicative Map of Archaeological Values that is used to predict the presence of archaeological sites. The insights gained are also relevant to other areas where Middle-Palaeolithic sites are affected by periglacial processes.

Abstract:

A considerable lack of agreement exists, particularly between French and English-speaking geomorphologists, on the precise use of many periglacial terms, and up to the presenty there bas been little correlation of the periglacial terminology of these two languages. Accordingly, the authors have prepared a bilingual glossary of 900 periglacial terms in an attempt to eliminate some of this confusion. Many of the problems encountered in the preparation of this glossary result from different conceptions of the terms « periglacial » and « périglaciaire ». Periglacial studies are generally considered to involve analyses of permanently frozen ground, patterned ground and frost-shattering, whereas the term « périglaciaire »refers to the systematic study of all « cold »processes (except those associated with glacier ice) and their resultant phenomena. The term thus includes, amongst other things, gelifraction, gelifluction, geliturbation, fluvioperiglacial action, effect of sea, lake, river and ground ice, windwork in areas of cold climate, action of snow, and chemical erosion by meltwater.

Abstract:

Periglacial conditions which occur in Canada have been studied recently. Most of the research has been so jar limited in scope (mostly patterned ground and permafrost), undertaken for practical purposes (v.g. airport strips and the new Aklavik's site) and often carried by governmental agencies. Though a hundred titles or so of various articles and notes could be cited in a bibliographical survey of the topic, it must be underlined that the inventory of periglacial phenomena itself is still jar from being completed. This paper, prepared for the Canadian Committee of the International Commission of Periglacial Geomorphology, is based on a broad conception of the topic. The author suggests a useful series of new analytical concepts and outlines new fields for future research. The paper deals with three major aspects of periglacial studies : processes, datation and regions. Some of the processes and conditions are : terrain, wind, vegetation, the climatic « facies » (frozen ground, snow, air temperature and floating ice System). The author feels that all periglacial phenomena in Canada can be classified within a chronological sequence which he makes an attempt to establish as follows : a) Lower and Middle Wisconsin ; b) Pleniwisconsin ; c) Finiwiscon-sin ; d) Late Glacial ; and, e) Recent. Canada, in the opinion of Dr. Hamelin, can be divided into eleven periglacial « provinces ». The first jour provinces : Elizabeth, Victoria, Keewatin and Innuit are closely associated with continuous permafrost. Three provinces, Hudson, Labrador and Mackenzie, are situated in the periarctic zone. Two, Alberta and Saint-Laurent, have a southern situation along the parallel 50°N. Finally, two provinces : Yukon and Columbia, lie within the limits of Western Cordillera. These eleven provinces are proposed to serve for the designation of periglacial types or regimes throughout the cold regions of the world. The paper concludes with a glossary of new terms suggested for adoption.

Abstract:

This paper presents the results of geomorphological research of the periglacial relief on mountain Crnook (1881 m) in Southeast Serbia. The results have showed the significant presence of modern periglacial morphology on this mountain which is developing in azonal conditions of a periglacial mountain environment. Research results from Crnook are significant because they represent the continuation of similar studies on medium-high mountains of Serbia (Kopaonik, Stara Planina). Based on a comparison of data from Kopaonik, Stara Planina and Crnook (Nesic D., Milincic M., 2004; Belij S. et al., 2008; Nesic D. et al., 2009; Nesic D., 2009), it can be concluded that in similar climatic frameworks with a significant share of anthropogenic activities, in terms of reducing the forest area in the highest parts of a mountain, similar modern periglacial processes develop on mountains as an indicator of azonal or boundary development framework of modern mountain periglacial environment. During 2006-07, the project "Modern periglacial geomorphic landforms on the mountains of Serbia" was initiated and the field research was conducted on the high mountains of Serbia (Stara Planina, Kopaonik, Kucaj, Beljanica, Zlatibor), and the mountains of Southeast Serbia (Vardenik, Besna Kobila, Dukat i Crnook).

Abstract:

AbstractThe major climatic variations that have affected the summit slopes of the higher Apennine massifs in the last 6000 yr are shown in alternating layers of organic matter-rich soils and alluvial, glacial and periglacial sediments. The burial of the soils, triggered by environmental–climatic variations, took place in several phases. For the last 3000 yr chronological correlations can be drawn between phases of glacial advance, scree and alluvial sedimentation and development of periglacial features. During some periods, the slopes were covered by vegetation up to 2700 m and beyond, while in other phases the same slopes were subject to glacial advances and periglacial processes, and alluvial sediments were deposited on the high plateaus. Around 5740–5590, 1560–1370 and 1300–970 cal yr B.P., organic matter-rich soils formed on slopes currently subject to periglacial and glacial processes; the mean annual temperature must therefore have been higher than at present. Furthermore, on the basis of the variations in the elevation of the lower limit reached by gelifraction, it can be concluded that the oscillations in the minimum winter temperatures could have ranged between 3.0°C lower (ca. 790–150 cal yr B.P.) and 1.2°C higher (ca. 5740–5590 cal yr B.P.) than present minimum winter temperatures. During the last 3000 yr the cold phases recorded by the Calderone Glacier advance in the Apennines essentially match basically the phases of glacial advance in the Alps.

Abstract:

In the medium-high mountains of Serbia (1,000-2,000 m.a.s.l), sporadic periglacial relief forms occur, which is also the case with Mount Vardenik (1,876 m.high), a mountain in the southeast of Serbia. During reconnaissance, certain relict and sub-recent periglacial phenomena and landforms in the highest part of the mountain have been identified: block slides, rock flows, thermogenic landslides in springs, nivation-induced relief and in one location cryoplanation terraces. Sparsely clustered and individual occurrences of frost splitting and solifluction of the land surface and small areas with grass turf indicate contemporary signs of sporadically present seasonal frost and freeze-thaw cycles. Periglacial morphology and its processes have been recorded and investigated using a qualitative geomorphological procedure. The main problem is the origin of periglacial phenomena (occurrences and landforms) of the relief, considering that the analysis of the contemporary climate, geoecological properties and anthropogenic activities indicate that there are no condi-tions for the existence and development of a contemporary periglacial environment on the mountain. The problem was analyzed considering the climate change in general and, in particular, geoecological conditions created under the influence of human activities. Due to the observed sporadic relict and sub-recent periglacial relief on Mount Vardenik, in contemporary conditions the periglacial environment of this area can be consid-ered as relict or as a phenomenon bordering the limits of differentiation. The relict property also results from the fact that on the mountain, due to the contemporary climate and changed geoecological conditions, the transition zone of the periglacial environment cannot be distinguished.

Abstract:

Periglacial landforms are typical features of the high mountain environment on the Balkan Peninsula. Their formation and diversity is determined by climatic, topographic and geological factors. Presently active periglacial processes occur above 1700-2000 m a. s. l., while relict features are observed down to 1100-1400 m a. s. l. Among the most prominent periglacial landforms are the extensive talus screes and fans, the numerous rock glaciers (especially in Rila, Pirin, Shar and Prokletije Mountains) – considered mostly relict – and nivation features (nivation cirques, long-lasting snow patches), as well as cryo-clastuc landforms (stone seas and strips). The present study aims to focus on the importance of geological conditions (bedrock composition and structure, tectonic settings) for the diversity and style of periglacial landforms – a factor, whose role has often been underestimated. The analysis and the derived conclusions are based mainly on regional and local comparisons between the high mountains throughout the peninsula.
