四川白玉增科铜铅锌多金属矿床特征及找矿

Geological Features and Prospecting for the Cuodeng-Anka Cu-Pb-Zn Polymetallic Deposit in Zengke, Baiyu, Sichuan

白玉增科乡错登-安卡地区铜铅锌多金属矿床主要赋存于晚三叠系勉戈组中-酸性火山岩及火山岩中的沉积岩和变质岩透镜体中,并受构造控制。矿石矿物以铜铅锌硫化物为主,且伴生银,属火山喷流沉积-热液叠加矿床。该地区已发现有嘎衣穷和胜莫隆铜铅锌多金属矿床,通过该矿床特征,分析阐述了该区找矿标志及找矿远景。

The Cuodeng-Anka Cu-Pb-Zn polymetallic deposit occurs mainly in acidic volcanic rock, sedimentary rock and lenticular metamorphic rock within the Late Triassic acidic rocks, being controlled by structure. Ore mineral is composed of Ag-bearing Cu-Pb-Zn sulfides. The deposit is volcanic exhalative sedimentary one. Geochemical features and prospecting potential are discussed.
