We have dated the South Delhi orogeny, Aravalli-Delhi Mobile Belt (ADMB), NW India, using tectonic fabric, geochemistry, and zircon-monazite geochronology as proxies. The Terrane (SDT), a passive margin domain in ADMB, consists of multiply deformed (D 1 –D 4 ) greenschist facies rocks several granite plutons. D deformation is characterized by pervasive isoclinal recumbent F fold axial planar te...

In the Southern São Francisco Craton near Itapecerica (Minas Gerais – Brazil) occurs a supracrustal succession of rocks, varying from bottom to top by quartzite, graphite schist, khondalitic paragneiss and banded iron formation whose protoliths are oceanic basin with ages in context Rhyacian-Orosirian orogeny. Amphibolite metaultramafic bodies occur associated this succession. Mineralogical tex...

The strata in the Shita Mountain, Yunkai region, are predominantly composed of clastic rocks with intercalated limestones. However, precise stratigraphic age remains uncertain due to scarcity fossils. Previously, conglomerate layers this region were considered indicative Yunan Orogeny during Cambrian–Ordovician transition. through identification 12 lithofacies types and 5 combinations Mountain ...

Abstract Fluid inclusion microthermometry of synkinematic veins is used to estimate the maximum syntectonic load that was deposited on wedge top in central Appalachians (northeastern United States) during Alleghanian orogeny. The restored loads indicate two major depocenters orogeny: one above Broadtop synclinorium, with as much 7 km Pennsylvanian–Permian probably sourced by erosion rocks uplif...
