摘　　要：通过对宝山矿区地质勘查、探采资料分析和调查研究,认为宝山夕卡岩型钨多金属矿床的形成明显受地层、岩性和接触带构造控制;成矿的有利部位是细粒斑状花岗岩或细粒花岗岩与中-上石炭统黄龙组-船山组碳酸盐岩接触带,工业矿体赋存部位是波状起伏的接触带,特别是突入岩体的"半岛式"灰岩捕虏体接触带,即所谓的"凹槽构造";预测在茅草沟区段深部-300^-500 m深处可能存在另一个大的凹槽构造,预测赋存厚大矿体。Baoshan ore deposit is a typical contact metasomatic skarn type tungsten polymetallic deposit, ore body morphology, occurrence and scale obviously controlled by strata, lithology and contact zone structure. This paper analyzes the relationship between granite, stratigraphy, tectonics and mineralization, drawing the conclusions that the favorable mineralization positions are fine-grained porphyritic granite or fine-grained granite, or the Upper Carboniferous Huanglong-CHUANSHAN Carbonate contact zone;industrial ore body portion is in contact with the undulating, especially the＂peninsula＂type limestone xenoliths broken into the contact zone of rock mass, the so-called＂groove structure＂. Existing geological data analysis showed another big notch construction may exists in-300^-500 m deep thatch groove section. Ore reserves were estimated up to about 600 000 t.
