塔尔沟地区1/5万矿产远景调查地质特征及找矿方向

Geological Characteristics and Prospecting Direction of 1:50000 MineralProspects Investigate of Taergou Area

祁连山西段塔尔沟地区,大地构造位置位于祁连山中间隆起带和北祁连地向斜带的结合部位。区域内构造发育,地层出露较齐全,前长城系是钨、钼、铜、铅、锌的主要赋矿层位;长城系朱龙关群浅变质低绿片岩相,是钨、钼、铜、铁的主要赋矿层位;蓟县系镜铁山群变质绿片岩相,是铁、铜矿床的主要赋矿层位。奥陶系阴沟群,为典型蛇绿岩建造,是北祁连火山岩型铜矿床的主要赋矿地层。因此,根据区域成矿条件和矿产分布规律分析,该区域为有色金属、黑色金属、贵金属矿产的产出地,矿产调查具有较好的前景。

Qilian Mountains area, western section of Taergou, located in tectonic uplift between Qilian and North Qilian belt to the binding site syncline. Tectonic development of the region, strata exposed more fully, the former Department of the Great Wall are tungsten, molybdenum, copper, lead, zinc ore bed of the main enabling places; the Great Wall, Department Zhulongguan group epimetamorphic low greenschist facies, are tungsten, molybdenum, copper, The main iron ore bed; Jixian Department Jingtieshan group greenschist facies metamorphism, are iron, copper deposit, the main ore bed spaces given. Ordovician Yingou group, for the construction of a typical ophiolite, North Qilian Mountains are volcanic-type copper deposit, the main ore formation. Thus, according to the regional ore-forming conditions and distribution of mineral analysis, in the region for non-ferrous metals, ferrous metals, precious metals and mineral output, mineral survey has good prospects
