Genesis of the late Ordovician Kukaazi Pb-Zn deposit in the western Kunlun orogen, NW China: New insights from in-situ trace elemental compositions of base metal sulfides

The Kukaazi Pb-Zn deposit was recently discovered in the western Kunlun orogen (WKO), NW China. This deposit consists of three ore blocks (KI to KIII) hosted in Mesoproterozoic metamorphosed rocks. Ores are mainly composed of sphalerite, galena, chalcopyrite and scheelite. Here we present in-situ LA-ICP-MS trace elemental compositions of sphalerite and galena of sulfide ores from ore blocks KI and KII, to shed light on the ore formation and its...
