Geological Characteristics of Ag-Pb Deposit in A He Lan, XinJiang

Abstract:

The Ag-Pb Deposit in A He Lan was located in the eastern of the East Kunlun with complex structure, strong magma activity and rich mineral resource. The silver lead-zinc bodies were hosted in Yanshanian biotite adamellite (Jηγ) and blackmica granite diorite (Jγδ) and controlled by the fracture zone. The orebodies produced in vein and lenticular with a length of 200m-820m, the average thickness of 0.42m-6.77m. The ore minerals were mainly galena and limonite and the gangue minerals were quartz, feldspar and biotite. The ore textures mainly contained xenomorphic granular, metasomatie-relict, entrapped, interspersed and cataclastic etc. And the major structures were crumb(granular), veinlet and block in the ore area. The ores were the zinc-lead-silver type rich in lead-silver and poor in zinc. The surrounding rocks were biotitemonzogranite (Jηγ) and the stones were the biotitemonzogranite cataclasite and breccia.
