the massive sulphide deposit at kantienpan cu-zn mine is hosted by volcano sedimentary succession known as the areachap group, in the eastern part of namaqua metamorphic province, south africa. the deposits were affected by a complex deformation and metamorphic history and represent examples of upper amphibolite to granulite grade metamorphosed volcanic-hosted massive sulphide (vhms) depo...

The extensional collapse of the Scandinavian Caledonides resulted in rapid tectonic denudation of the orogen, exhumation of highand ultra-high-pressure metamorphic rocks and provided a structural template for the formation of Devonian supra-detachment sedimentary basins. The geometry and intensity of the extensional deformation show considerable variation vertically in the crustal section as we...

The Meatiq basement, which is exposed beneath late Proterozoic nappes of supracrustal rocks in the Central Eastern Desert of Egypt, was affected by three metamorphic events. The ophiolite cover nappes show only the last metamorphic overprint. The M1 metamorphic event (T≥750 °C) is restricted to migmatized amphibolite xenoliths within the Um Ba∞anib orthogneiss in the structurally lowest parts o...
