云南漾濞县公岩子金矿地质特征及找矿前景

THE GEOLOGICAL FEATURE AND PROSPECTING POTENTIALITY OF GONGYANZI AU DEPOSIT IN YANGBI,YUNNAN

云南漾濞县公岩子金矿矿体、矿化体呈似层状、脉状断层构造破碎带中,矿体顶、底板围岩分别为上三叠统挖鲁八组(T3wl)及上三叠统三合洞组(T3s),该金矿为断层构造控制的中-低温热液型矿床。从本矿区良好的成矿地质条,以及强烈的Au土壤地球化学异常显示了本矿区具有良好的找矿前景。

The Orebody,metallogenetic body of Gongyanzi Au deposit in Yangbi,Yunnan are stratoid,veined in the structure fracture zone.The top,bottom wall rocks are separately Upper T Waluba Formation(T3wl)and Upper T sanhedong Formation(T3s).It is a middle-Low T hydrothermal deposit controlled by fault structure.The good geological conditions and intense Au soil geochemical anomaly show that the prospecting potentiality is excellent in this orefield.
