摘要
作者认为,桃林铅锌矿床位于区域向斜的北翼,赋存在上震旦统陡山沱组和灯影组层位中,地层与构造控制明显,属沉积-热液改造型萤石铅锌矿床.在此认识的基础上,圈出了3个找矿预测区,并对坳背屋找矿预测已设计深部验证工程,施工9个钻孔,均见工业矿体.
In author's opinion, the Taolin Pb-Zn deposit is situated in the northern limb of the regionalsyncline and occurs in the upper Sinian Doushantuo and Dengying Formations. It is a fluorite Pb-Zndeposit of sedimentary-hydrothermal reformed type and distinctly governed by stratigraphy and tectonics. On the basis of such an understanding, three prospect areas were delineated by metallogenic prognosis and one of the areas (Aobeiwu) was tested by nine drill holes whieh encountered commercialore bodies at depth.
