文章在研究闽中地区铅锌矿床蚀变矿物组合的基础上,将辉石矿物的化学成分与典型矽卡岩Pb_Zn矿床的辉石成分进行了对比,认为该区铅锌矿床的辉石与典型矽卡岩中的辉石类似,为透辉石和钙铁辉石,富锰,具有远温端矽卡岩辉石的特征。因此推论本区铅锌矿床大部分类似于矽卡岩型Pb_Zn矿床,少数为受断裂控制的热液脉型矿床,是海底火山喷发沉积形成的初始矿源层经变质作用、燕山期构造_岩浆热液顺层交代、强烈叠加改造或活化并重新定位的矿床。
Based on the study of alteration mineral assemblages of lead-zinc deposits in Central Fujian Province, the chemical compositions of pyroxene minerals are compared with the pyroxene constituents of typical skarn Pb_Zn deposits. It is concluded that pyroxene in typical Pb Similar to pyroxene in skarn, it is characterized by diopside and calcium-iron-pyroxene, manganese-rich, pyroxene with distal temperature ends. Therefore, it is inferred that most Pb-Zn deposits in this area are similar to skarn type Pb_Zn deposits, and a few are fault-controlled hydrothermal veins deposits. The original source beds formed by submarine volcanic eruptions are metamorphosed, and the Yanshanian tectono-magmatic heat Liquid layers explain, strongly superimposed rebuilt or activated and repositioned deposit.
