甘肃席芨水地区金矿床地质特征
Geologic characteristics of the gold deposit in Xijishui, Gansu
摘要
Abstract
The Hongwowo and Dongwantaizi gold deposit locates in the eastern section of the north Qilian orogen. The ore body occurs in Mayinggou group of lower Silurian system and is of vein or lenticular shape. Mineralization originates in the fault and fracture zone of meta-sandstones, altered diorite and chipped altered sandstone. Alteration types contain silicification, pyritization, ferritization, choritization and kaolinization. Silicification is the main one. Research shows that the source bed of gold is Mayinggou group of lower Silurian system. The quartz diorite probably provides mineralization with dynamics, thermal and part of the ore source. The main ore elements Au is closely tied up with Cu, Pb, Zn, Ag, As and Mo. The formation of the gold deposit is controlled jointly by above mentioned stratum, structure and intrusive rock.关键词
