Abstract:
AbstractThe Bahram-Gur area in the southeastern part of the Sanandaj – Sirjan metamorphic zone, contains metabasites and metasediments. The metasedimentary rocks are mainly garnet schists and garnet-staurolite schists that were metamorphosed under amphibolite facies conditions. The rocks consist of garnet ± staurolite, biotite, muscovite, chlorite and quartz. The geochemistry of the Bahram-Gur metasediments classifies them as quartziferous sedimentary rocks. The protoliths of the metasedimentary rocks were close to greywackes from an ensialic arc basin depositional setting, with a source compr

Abstract:
This group of Archean volcanic and metasedimentary rocks is generally considered to be younger than the Keewatin metavolcanic rocks. The metasedimentary rocks are disposed in tight to isoclinal folds with strong plunge variations that are mainly due to a primary tectonic event. The folds are accompanied by a single, penetrative tectonic microfabric and a coplanar magnetic fabric. The contacts of the group with the adjacent Keewatin rocks are unexposed but are inferred to be faulted, at least in part.

Fluids, mainly H2O and CO2, are released from H- and C-bearing phases during prograde metamorphism. Because of the buoyancy of these fluids, they rise within the crust towards the surface of the Earth. Metamorphic fluids take advantage of permeable horizons, shear zones, fold hinges, fractures, and are channelled into high-flux zones. Fluid fluxes for channelized fluid flow may exceed background pervasive fluxes by several orders of magnitude. Metamorphic fluids react with the surrounding rock during fluid flow, and altered zones are commonly observed adjacent to high-flux conduits. Fluid-alte

Abstract:
ABSTRACT The ophiolite of the Buck Creek and Chunky Gal Mountain areas (North Carolina, USA) consist of very high-temperature mafic and ultramafic units. These mafic and ultramafic rocks were once part of the oceanic lithosphere before being subducted and then thrust into continental rock by the Taconic orogeny, which took place during the Paleozoic era. The thrusting of these mafic and ultramafic rocks into nearby metasedimentary rock was controlled by the Chunky Gal thrust fault. Studies on this ophiolite were mainly petrological, geochemical, and structural in nature. The main rocks of interest within this area are dunite, metatroctolite, and amphibolite. The dunite mostly consists of olivine and minor chromite spinels. Hydrous altered dunite may also consist of antigorite, chlorite, talc, and anthophyllite. This dunite is associated with minor scattered lenses of metatroctolite. The metatroctolite is dominated by plagioclase and olivine, which have symplectites and/or coronas of prograde minerals such as pyroxene, spinel, and sapphirine. Some of this metatroctolite was altered via hydration into chlorite schist and edenite-margarite schist, some of which is corundum-bearing. The dunite and metatroctolite are separated from the surrounding metasedimentary units by the surrounding Chunky Gal Amphibolite. This amphibolite, whose protolith is basaltic/gabbroic, is dominated by hornblende and plagioclase.

Abstract:
ABSTRACT Granitoid batholiths dominated by felsic to intermediate compositions are commonly associated with mafic plutons and enclaves; however, the genetic relationship between the apparently coeval but compositionally dissimilar magmas is unclear. Here, we reviewed the age and lithogeochemical and Nd-Sr isotopic compositions of some classic plutonic rocks emplaced in the Northern Highlands, Grampian and Connemara terranes of the Caledonide orogen of Scotland and Ireland. The Northern Highlands terrane consists mostly of Neoproterozoic metasedimentary rocks of the Moine Supergroup and is located north of the Great Glen fault. The Grampian terrane also consists of Neoproterozoic metasedimentary rocks (Dalradian Supergroup) and is located south of the Great Glen fault in both Scotland and Ireland. Amphibolite-facies metasedimentary rocks in the Connemara terrane are correlated with the Dalradian Supergroup, and the terrane is bounded by splays of the Highland Boundary and Southern Uplands faults. These three terranes were intruded by Silurian–Devonian mafic and felsic to intermediate plutonic rocks that display field evidence for mingling and mixing and have a similar range (between ca. 437 and 370 Ma) in emplacement ages. This range implies they were intruded during and after the late Caledonian Scandian orogenic event that resulted from the mid- to late Silurian collision of amalgamated Avalonia and Baltica with Laurentia and the final closure of the Iapetus Ocean. Our review supports the contention that the Great Glen fault represents a major compositional boundary in the Silurian lithosphere. Felsic to intermediate plutons that occur north of the Great Glen fault are more enriched in light rare earth elements and Ba-Sr-K compared to those to the south. Isotopic compositions of these late Caledonian plutonic rocks on both sides of the Great Glen fault indicate that metasomatism and enrichment of the subcontinental lithospheric mantle beneath the Northern Highlands terrane occurred just prior to emplacement of late Caledonian plutons. Within the same terrane, mafic and felsic to intermediate rocks display similar trace-element and rare earth element concentrations compatible with models implying that fractionation of a mafic magma played an important role in generating the felsic to intermediate magmas. The onset of slab failure magmatism may have been diachronous along the length of the collision zone. If so, slab failure may have propagated laterally, possibly initiating where promontories collided.

ABSTRACT The discovery of multiple deformed and metamorphosed sedimentary successions in southwestern Laurentia that have depositional ages between ca. 1.50 and 1.45 Ga marked a turning point in our understanding of the Mesoproterozoic tectonic evolution of the continent and its interactions with formerly adjacent cratons. Detrital zircon U-Pb ages from metasedimentary strata and igneous U-Pb zircon ages from interbedded metavolcanic rocks in Arizona and New Mexico provide unequivocal evidence for ca. 1.50–1.45 Ga deposition and burial, followed by ca. 1.45 and younger deformation, metamorphism, and plutonism. These events reflect regional shortening and crustal thickening that are most consistent with convergent to collisional orogenesis—the Mesoproterozoic Picuris orogeny—in southwestern Laurentia. Similar metasedimentary successions documented in the midcontinent of the United States and in eastern Canada help to establish ca. 1.45 Ga orogenesis as a continent-scale phenomenon associated with a complex and evolving convergent margin along southern Laurentia. Metasedimentary successions of similar age are also exposed across ~5000 km of the western Laurentian margin and contain distinctive 1.6–1.5 Ga detrital zircon populations that are globally rare except in select cratonic provinces in Australia and Antarctica. The recognition of these distinctive detrital zircon ages provides a transient record of plate interactions prior to breakup of Nuna or Columbia ca. 1.45 Ga and provides key constraints on global plate reconstructions.

Abstract:
The eastern Circum-Rhodope belt (CRB) is a major unit that surrounds both the Serbo-Macedonian and the Rhodope zones in the Alpine orogen of the northern Aegean region. This belt contains Triassic-Jurassic metasedimentary successions and Middle Jurassic (176-165 Ma) supra-subduction zone Evros ophiolite. The latter has experienced ocean-floor hydrothermal metamorphism or very-low to low-grade metamorphism. We report on mineral compositions of rock-forming minerals in schist and mafic rocks from the eastern CRB. Our goal is to use the mineral compositions to assess the metamorphic conditions su

Abstract:
The Boothia Peninsula - Somerset Island region of north-central Nunavut is a frontier region (70-74°N, 94°W) long considered as part of Rae craton. Recent field mapping and acquisition of isotopic (U-Pb, Sm-Nd) data as part of the GEM-2 Boothia-Somerset project allowed this region's exposed Precambrian bedrock to be better characterized with respect to petrology and litho-geochemistry, and to be more extensively and more precisely time-calibrated.

The distribution of pyrite and pyrrhotite is documented within an andalusite-sillimanite type (high-temperature, low-pressure) metasedimentary succession exposed in the Hyland River region of southeastern Yukon, Canada. The following metamorphic zones are recognized: chlorite, biotite, cordierite/staurolite (porphyroblast-in), andalusite, sillimanite, and K-feldspar + sillimanite. Pyrite occurs in the chlorite zone through the biotite zone, while pyrrhotite occurs from the chlorite zone to K-feldspar + sillimanite zone. The pyrite-pyrrhotite transition, therefore, occupies an interval in the c
