摘要
湖南新邵大新金矿位于华南地槽褶皱系与扬子准地台接壤地带边缘,湘中岩石圈古俯冲带内。矿区共发现矿脉14条,圈定Au矿体10个。Au的赋存状态大约可分为三类,主要赋存于硫化物中,少量被褐铁矿、有机碳等吸附。矿床的形成具多期次多阶段成矿特点。
The Hunan Sinshao Daxin gold deposit is located the South China geosyncline system of fold and the Yangzi paraplatform borders on the region edge and in in the Middle of Hunan lithosphere ancient dive belt. The mining area altogether discovered 14 mineral lode, select 10 Au ore body. The Au tax saves the condition to be possible to divide into three kinds approximately, the main tax saves in the sulfide, few by adsorptions and so on limonite, organic carbon. The ore deposit formation has the time stage mineralization characteristic.
