湘西花垣铅锌矿田李梅矿区地质特征及闪锌矿中分散元素的富集规律
Geological characteristics and enrichment law of the dispersed elements of the sphalerite in the Huayuan ore fields of Limei Pb-Zn deposit, western Hunan province
摘要
Abstract
The mineral resources are rich in western Hunan,which is an important part of the metallogenic belt of western Hunan and western Hubei.Hunan hua yuan lead-zinc ore field is located in the south edge of the upper Yangtze plate,and is the national lead-zinc deposit exploration area.Based on the observation of the common mi-croscope and the means of electron microprobe analysis,the authors analyze the dispersed elements of cadmium and germanium and gallium in the ore and minerals and the structure characteristics of ore structure from the Huayan ore fields in Limei Pb-Zn deposit of west of Hunan,it is considered that the deposit is characterized by enrichment of cadmium,with a lower degree of enrichment of germanium and gallium.Cadmium is mainly con-centrated in sphalerite,and germanium and gallium are mainly concentrated in galena. In the primary sulphide sphalerite,galena and pyrite,the occurrence status of the dispersed elements cadmium,germanium and gallium in the Pb-Zn deposit exist as isomorphism,and no independent minerals have been found.The enrichment charac-teristics of dispersed elements are similar to MVT deposits.Ore deposit with height of cadmium enrichment,which is the ideal region in study of dispersed element cadmium geochemical characheristics.关键词
