玲珑金矿大开头矿区Bi特征及指示意义
Bi anomaly of the Dakaitou ore district in the Linglong gold mine and its indication significance
摘要
Abstract
In gold deposits, Au and Bi are often associated with each other. Around the gold orebody, there exists obvious Bi anomaly, which can serve as an important indicator element. The authors investigated the relationship between Bi and Au content in different rocks within the Linglong gold mine, comparatively studied the correlation of these two elements in the bedrock geochemical profile, and analyzed Bi and Au content in main ore minerals by means of electron microprobe analysis. Some conclusions have been reached:Bi values are remarkably different in different kinds of rocks, Bi values in the orebody are by far higher than its values in the wall rock, Bi and Au show power function positive correlation in the ore district, Bi primary halo is of large size and high contrast, and both Bi and Au exist as independent minerals. Geochemical prospecting in the Linglong gold mine shows that Bi is of high content, has fairly good positive correlation with Au and thus can serve as one of the best indicator elements.关键词
