Two‐stage magmatism and mineralization of Tulaergen nickel‐copper deposit in eastern Tianshan, North‐west China: Evidence from bulk rock geochemistry and in situ mineral chemistry

Abstract

The Tulaergen magmatic Ni-Cu deposit is related to mafic-ultramafic rocks of the Central Asian Orogenic Belt. The ore-host rocks are lherzolite and websterite and the major ore types are net-textured and sparsely disseminated ores. The disseminated ores host high-Fo (82-85) olivine and hornblende with low-Al contents, high-rare
