新疆唐巴勒孜北金矿地质特征及找矿标志

Geological characteristics and prospecting dicator of Tangbalezi gold deposits,Xinjiang

新疆青河县唐巴勒孜北金矿区位于阿尔泰山南缘东段,矿区出露地层主要为下石炭统姜巴斯套组第一段(C_1j^1)、下石炭统姜巴斯套组第二段(C_1j^2)以及第四系(Q),其中下石炭统姜巴斯套组第一段为主要含矿地层。矿体呈脉状产于蚀变破碎岩中,金矿化与蚀变岩关系密切,矿体明显受断裂构造的控制,产状较陡,矿床成因类型为蚀变岩型,强烈的围岩蚀变部位及韧性剪切带中的石英脉就是矿体或矿化体的赋存部位,是最直接的找矿标志。

The tangbalize northern gold mining area in Qing he, Xinjiang is located in the eastern part of the southern margin of Altai mountains. the exposed strata of the mining area are mainly the first segment （C1j1）, the second segment （C1j2） and the quaternary （Q） of the lower carboniferous jiangbastao formation. the first segment （C1j1） of the lower carboniferous jiangbastao formation is the main ore-bearing strata of the mining area. The orebody occurs in vein shape in altered broken rock （ductile shear zone）, and gold mineralization is closely related to altered rock. the orebody is obviously controlled by fault structure, and its occurrence is steep. the genetic type of the deposit is altered rock type. the strong alteration position of surrounding rock and the quartz vein in ductile shear zone are often the occurrence position of orebody or mineralizer, which are the most direct prospecting indicators.
