摘要
近几年来,鄂西铅锌矿的找矿勘探工作获得重大进展,关于矿床成因类型的问题也逐渐成为了研究的一个热点。从喷流沉积型(SEDEX)及密西西比河谷型(MVT)铅锌矿床的特征研究入手,辨证地阐述了两者之间的关系,通过分析对比鄂西铅锌矿与喷流沉积型(SEDEX)及密西西比河谷型(MVT)典型铅锌矿床之间的关系,建立起鄂西铅锌矿的成因模式,并提出了同生断裂、断陷盆地+有利岩性、构造沉积组合的找矿思路。
In recent years, the exploration of lead-zinc has achieved great progress, and the research of genesis type of lead-zinc deposit becomes a focus. The authors begin with the study of SEDEX and MVT,illustrate the relationship between them dialectically,and analyses the lead-zinc deposit in western Hubei with SEDEX and MVT deposits,set up the genesis model of lead-zinc deposit in western Hubei,finally, the author presents the method for lead-zinc deposit prospecting in western Hubei,that is,contemporaneous fault,downfauhed basin with favorable lithology and lithofacies.
