王仙岭地区锡多金属矿找矿前景浅析

ELEMENTARY DISCUSSION ON PROSPECT FOREGROUND OF Sn POLYMETALLIC DEPOSIT AT WANGXIANLING AREA

位于炎陵—蓝山重力梯度带中的耒阳—临武向构造带与茶陵—永兴坳陷带复合部SN位的王仙岭地区,断裂构造发育、岩浆活动强烈,其中向断裂为主要控岩控矿构造。王仙岭NE花岗岩体、、、、、等成矿元素丰度值高,已发现锡多金属等矿床(点)处。WSnMoBiBeNb39区内、、、、、、化探异常规模大、强度高,具水平分带现象。根据区域成矿WSnPbZnAuAgAs地质条件、成矿规律、物化探异常,结合以往找矿成果及最新的民采资料,圈定了野鸡窝、大壁口、龙潭和水源山个锡多金属矿远景预测区,并提出了找矿工作部署建议。

Wangxianling area is situated on the compounded place between Leiyang-Linwu SN orientation structure zone and Yongxing depression zone of Yanling-Lianshan gravity gradient zone. In this area, the fault structures develop very well and magma action is strong, and the NE strike fault is the main structure of lithosome-controlled and ore-controlled. The metallogenic element abundance, e.g. W, Sn, Mo, Bi, Be, Nb, is higher, 39 deposits(spots) of Sn polymetallic have been found in this area. The geochemical exploration anomaly of W, Sn, Pb, Zn, Au, Ag, As have large scale, high intensity and phenomena of horizontal zoning. Based on the regional metallogenic geological condition, the metallogenic regular, the geophysical and geochemical exploration anomaly, combination with achievements of looking for minerals and the newest data private excavating, the authors draw out the following 4 foreground forecasting areas of Sn polymetallic, i.e. Yeji'ou, Dabikou, Longtan and Shuiyuanshan, and put forward the suggestion of looking for minerals in future.
