Low–pressure metamorphism of mafic granulites in the Chinese Altay orogen, NW China: P–T path, U–Pb ages and tectonic implications

Mafic granulites occur as massive lenses within host paragneisses at Wuqiagou area in the southern Chinese Altay orogen. They comprise a suite of fine–grained and coarse–grained mafic granulites, both characterized by an assemblage of orthopyroxene, clinopyroxene, hornblende, biotite, plagioclase, quartz, Fe–Ti oxides, minor K–feldspar, and accessary apatite and zircon. The peak– and post–peak metamorphism evolution is respectively represented...
