摘　　要：个旧锡矿马拉格矿开采历史悠久,现属于资源危机矿山。根据以往研究,个旧市地区锡矿与中三叠统个旧组(T_(2)g_(1)^(6))特定岩性、、入字型构造、花岗岩的侵入活动等关系密切。在马拉格矿田的小大坡、猴子山、小石岗、莲花山等地段同样具备上述成矿条件,加之这些地段还具有良好的Sn、As、Cu、Pb、Zn、Mn多元素原生晕,以及可控源音频大地电磁测量低阻异常,显示了该矿田还有较好的找矿前景。Malage mine of Gejiu Sn deposit has a very long mining history,the resource crisis has taken place.According to the past study,Gejiu Sn deposit is in close relation to the special lithologic character of Middle T Gejiu Formation(T_(2)g_(1)^(6)),λ-form structure and granite intrusion.There are the same metallogenesis conditions at Xiaodapo,Houzishan,Xiaoshigang,Lianhuashan,etc of Malage orefield.Moreover,there are good Sn,As,Cu,Pb,Zn,Mn,etc original haloes and controllable origin audio magnetotelluric low sistence anomaly,showing there is the good prospecting potentiality of this orefield.
