Abstract:The Galihe Copper Deposit is located in the Lancangjiang volcanic arc of “Sanjiang Tethyan” tectonic domain. This mining area is characterized by the strong metamorphism, magmatic activity and the strong tectonic movement, where has the superior metallogenic condition. This special geological environment provides rich ore-forming material source to the Galihe Copper Deposit. The main ore-bearing stratum is the upper Triassic Xiaodingxi Formation, and the ore-bearing rock include the andesite, andesitic basalt and altered andesite. The ore bodies occur as stratified, stratiform-like and lenticular, which are controlled by NE-and-NW trend structural fracture. There are positive correlations between the mineralization and limonitization, silicification, calcilization. This paper summarize the metallogenic geological characteristics and mineralization law. The results show that the mineralization has obvious variation along the horizontal direction but the stability along the thickness direction. This research indicates that the Galihe Copper Deposit has gone through the early syngenetic ore-forming process and the later hydrothermal-superimposition. Therefore, the genesis of deposit has been determined as a medium-low temperature hydrothermal copper deposit related to volcanic-magmatic intrusion.
