【 摘 要 】

Haxiyatu iron-polymetallic deposit in Qinghai East Kunlun is a typical regional strata bound skarn ore deposits, the major ore-host rock is Jinshuikou rock group and the metallogenic epoch is the early Triassic. This paper studied the amphibole, epidote, garnet and pyroxene, garnet and petrographic of Haxiyatu skarn deposit, divided the deposit alteration zoning characteristics in detail, and according to the mineral assemblages and skarn deposit mineral sequence, figured out three formation periods, including the skarn deposit stage, degenerate alteration stage and metal sulfide stage.
