Abstract: Abstract We determined SHRIMP U-Pb ages of zircons from three mafic granulite samples of the polymetamorphosed, multiply-deformed Kondapalli-Ongole domain of the Eastern Ghats Belt (EGB), SE India. Our goals are: (1) to evaluate the origin… read more here.

Abstract: Abstract Garnet-bearing mafic granulites occur as lenses within TTG gneiss or metapelite in the Fuping Complex, middle Palaeoproterozoic Trans-North China Orogen. They are composed mainly of garnet, clinopyroxene, orthopyroxene, hornblende, plagioclase, quartz and accessary zircon… read more here.

DOI: 10.1016/j.precamres.2018.04.022
Abstract: Abstract The Hengshan complex has drawn attention for the occurrence of typical high-pressure mafic granulites, representing the Paleoproterozoic collisional orogeny in the North China Craton. Mafic granulites occur as boudins of various scales in tonalite–trondhjemite–granodiorite… read more here.
