| 摘 要： | 陇英大地金矿位于大黑山背斜北翼，金矿产于F2断层两盘的层间破碎带、软弱带及节理、裂隙中，呈脉状、树枝状。容矿岩石主要为凝灰岩、破碎蚀变的拉斑玄武岩、沉凝灰岩。Au、As、Hg、Sb浓集于F2断层破碎带及其两盘节理裂隙发育地带，异常套合较好，与金矿化带相吻合，是化探找金良好的指示元素。Au、As、Hg、Sb具分带规律：As（前缘晕）-Hg（中晕）-Sb（中晕）-Au（尾晕）。As、Hg、Sb异常的面积、浓集带（Ⅲ级异常）面积、强度、规模远不及Au异常，表明矿体剥蚀严重。因此，认为本区及地质构造环境相似的地区，以Au、As、Hg、Sb为指示元素，根据异常组合特征、分带规律等，进行化探找金，具有重要的指导意义。

| Abstract: | Dadi gold mine situated in the north Daheishan anticline,the gold mine was found in interstratified fracture zone,weak zone,joint and cranny of fault F2,the appearances are nervation and arborizition.The ore-hosting rocks mainly are tuff,cracked and alternated tholeiite and sedimentary tuff.Au,As,Hg,Sb concentrated in the fault-cracked belt and cranny developed zone of the joints,the abnormality overlap was fine and dovetailed with the gold ore belt,are the good indicator elements for chemical prospecting.A... |
