对本区矿床成因的研究,早在半个多世纪以前就开始了.最早认为成矿与燕山期酸性岩浆活动有关,随后提出成矿与海西期基性岩浆活动有关.近年来,多数地质学家认为属于沉积改造矿床,但也有人提出属于渗流高氯热卤水矿床.作者就近年来收集到的硫、铅同位素资料,对本区铅锌矿床的成矿模式进行初步探讨,错误之处,请批评指正. 区域地质概况区内沉积地层发育完全,铅锌矿床均赋存于不同地质时代的碳酸盐岩层内,属于典型的层控铅锌矿床.控矿层位有上震旦统灯影组、下寒武
The study on the genesis of the deposit in this area started as early as half a century ago, and the earliest thought is that the mineralization is related to the Yanshanian acid magmatism, and then the mineralization is related to the Hercynian magmatic activity.In recent years, most geology However, it is also proposed to belong to the high-chloride hot-brine deposits in percolation.On the basis of the sulfur and lead isotope data collected in recent years, the author makes a preliminary study on the metallogenic model of lead-zinc deposits in this area, Correction.Regional Geological Survey The sedimentary strata in the area are well developed and the lead-zinc deposits are hosted in carbonate layers of different geologic times and are typical stratabound lead-zinc deposits.
