Baimazhai Ni-Cu-(PGE) deposit, Jinping Co., Honghe Autonomous Prefecture, Yunnan Province, China

StandardDetailedBy ChemistryMapsSearch Google

Ni–Cu–(PGE) sulfide deposit, hosted in a small mafic–ultramafic intrusion, which intruded Ordovician sandstone and slate. The intrusion is concentric with lens shape, about 530 m long, 190 m wide and 24 to 64 m thick, trends 296°, and dips 22°NE. The massive sulfide ore body forms the core of the intrusion and is surrounded by variably mineralized orthopyroxenite, websterite and barren gabbro.
