摘要
研究区大地构造位置处于西域板块,东昆中新元古代—早古生代缝合带。矿床类型属岩浆期后热液交代矿床,奥陶系滩间山群碳酸岩岩组是主要赋矿层位,岩体(脉)与碳酸盐岩的接触带附近的断裂含矿热液活动的有利场所,中酸性侵入岩与碳酸盐岩接触带、围岩蚀变都是重要的找矿标志。
The geotectonic location of the study area is located in the western plate,the Neoproterozoic-early Paleozoic suture zone in the Dongkun area.The type of deposit belongs to the post-magmatic hydrothermal metamorphic deposit.The Ordovician Tanjianshan group carbonate rock group is the main ore-bearing stratum,and the fracture-bearing hydrothermal activity near the contact zone between the rock mass(pulse)and the carbonate rock In favorable places,medium-acid intrusive rocks and carbonate rock contact belts and surrounding rock alterations are important prospecting indicators.
