摘　　要：铅锌矿是我国的一种重要的金属矿产。为提高云南地区铅锌矿储量,在保山核桃坪地区进行矿产勘探。通过储量评估、构造分析、样品测试及数据分析,认为岩石(性)控矿十分明显,成矿作用与矽卡岩化密切相关。此地段内磁异常、化探异常,集中分布于核桃坪组及柳水组地层之上,与已知矿床(点)对应较好。已具备一定远景的矿点有陡崖、上厂、草山等。核桃坪铅锌矿的评价和突破,对整个矿区远景扩大具有一定的指导意义。预测整个矿区远景储量可达30—40万吨。Pb-Zn deposit is a very important metal mineral in China. In order to improve the Yunnan Pb-ZN ore reserves, in Baoshan Hetaoping of mineral exploration. Through the reserves evaluation, structural analysis, sample test and data analysis, holds that obvious litho logic control and the mineralization is closely associated with sk-arnization. In this section, magnetic anomaly, geochemical anomaly concentration distribute in Hetaoping group and Liushui group formation, corresponding well with known deposit and ore occurrences. Douya, Shangchang, Caoshang and some other deposits and ore occurrences have some potential. Evaluation and break though of Hetaoping Pb-Zn deposit, have some guidance significance to enlarge prospect, predict the whole reserves is about 300-400 thou-sand ton.
