In Western Himalayan Syntaxis, the India-Asia continental collision occurred at ca. 50 Ma, while its uplift history and exhumation mechanism are still in dispute despite decades of studies. A new type eclogite was found Naran, located 30 km southwest Upper Kaghan Valley. Phase equilibrium calculations thermobarometer performed on Naran documented peak-P metamorphic condition 720–780°C 2.4–2.8 G...

This paper is an outgrowth of the compilation of metamorphic information for the Canadian Shield in Ontario, and complements the recently compiled Metamorphic Map of the Canadian Shield. The paper contains a summary of the Archean metamorphic history of the Superior Province in Ontario on a subprovince basis, with an emphasis on the limitations of the existing data and the reasoning applied in ...

Early Jurassic U-Pb age is obtained for both foliated and undeformed granites on Horseshoe Island, Antarctic Peninsula. Some microstructures in the granites/orthogneisses indicate high-temperature greenschist or low- to medium-temperature amphibolite facies deformation conditions. Additionally, a Late Cretaceous yielded gabbro intruding deformed granitoids.

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...

Abstract The Meran-Mauls nappe stack is part of the Austroalpine unit in South Tyrol (Italy). There it holds a special position directly front Southalpine Dolomites indenter and west Tauern Window. It situated hanging wall unit, above NW dipping segment Periadriatic fault system, namely fault. Also all other sides are defined by Oligocene-Miocene strike-slip normal faults. Based on recent mappi...
