新疆天神北铅锌矿区成因探讨及找矿标志

Discussion on genesis and prospecting marks of Tianshen north pb-zn deposit in Xinjiang

天神北铅锌矿床位于中生代裂陷盆地内,地层区划属于喀喇昆仑地层区,区内地层发育较全。矿区主要出露地层为侏罗系龙山组和白垩系铁龙滩群;区内发育有一条近南北向断裂(乔尔天山-岔路口断裂带),断裂附近矿化较明显。结合区域地质背景、矿区地质特征、矿体特征,初步分析了天神北铅锌矿床的类型及找矿标志。

Tianshen north lead-zinc beds are located in the basin of Mesozoic basin,whose stratigraphic regionalization belongs to the karakorum stratigraphic area,with complete formation development in the area.Mining area are mainly exposed to the longshan group of Jurassic and cretaceous iron longtan group;There is a nearly ns-trending fault zone development（Joel tianshan-fork fault zone）,near which the fracture mineralization is obvious.Combined with regional geological background,geological characteristics,ore body characteristics,this thesis analyzes the Tianshen north pb-zn deposit types and prospecting marks.
