摘要
空介铅锌矿产于二叠系灰岩和第三系雅西措组(砂质灰岩)地层的接触带上,围岩出现碳酸盐化和硅化等蚀变。初步认为其矿床成因为与新生代逆冲推覆断裂构造有关的中-低温热液型矿床,其矿床类型属密西西比河谷型铅锌矿床,矿床特征与我国云南金顶铅锌矿床较为相似。
Kongjie lead-zinc deposit was outputted on the contact zone between sparite of Permian System and calcarenite of Paleo-Neogene,the wallrock alteration includes carbonatization and Si-alteration,its genetic origin type is meso-epithermal deposit concerned with overthrust（nappe）of Cenozoic Era,its mineral type should be like Mississippi-valley,and is like Jinding lead-zinc deposit of Yunnan Province in deposit characteristics.
