| 摘 要： | 通过对兰坪金顶铅锌矿的最新野外调查以及相关的钻孔资料发现,膏盐在地表以及地下的产出形态与铅锌矿体密切相关。通常矿化程度高的主矿体部位膏盐也特别发育,盐丘底辟也影响着矿体的矿化蚀变分带,矿石特征以及矿物组合从盐丘的中心向矿化围岩呈现有规律的变化。同时,铅锌矿床所需大量的H2S主要是以硫酸盐的热化学还原成因(TSR)形成的,矿区地层大量的膏盐体是H2S的主要物源。

| Abstract: | According to the latest observation of Jinding Pb-Zn deposits in Lanping and the study of Borehole data,the form of gypsum underground and on the surface is closely related to the Pb-Zn body.Gypsum grows usually in the area of main body of high degree of mineralization.Salt domes also influence the zoning of the mineralization and alteration of the ore body.There are many regular changes in the characteristics of ore and mineral assemblages from the center of the salt dome to the mineralized wall rock.At the same time,large amount of H2S appear because of the thermochemical reduction reaction of sulfate(TSR) in Pb-Zn deposit.The large number of gypsum in mining strata layers is the main source of the H2S. |
