摘要
白玉县嘎衣穷矿区经过三年的激发极化法测量工作,圈定了南北两个长达2200m的激电异常带,在异常带中进一步圈定了8个局部异常,其中Ⅱ_1号异常长440m,宽10—20m,经工程查证,圈定多金属矿体长360m,平均厚度9.11m;Ⅱ_2、Ⅲ_3号异常长约1300m,宽约20—60m,经工程查证,圈定多金属矿体长870m,地表最大厚度21.4m。通过激电工作同时发现了矿区南东部位的大规模异常,经少量地表、深部工程控制也已见到了多金属矿体。嘎衣穷矿床属火山岩型多金属矿床,地质、地球物理条件对开展激电工作都较有利,所以取得了较好的找矿效果。
Gayiqiong deposit is a volcanogenic polymetallic ore deposit. Its geological and geophysical condi-tions are advantageous to the utilization of induced polarization method. Two induced polarization anomalous fields with a total length of 2200 m have been outlined in Gayiqiong polymetallic ore dis-trict in three years (1987-1989). The said two induced polarization anomalous fields consist of 8 lo-cal anomalies. Anomaly Ⅱ1 is 440 m long and 10-20 m wode within the scope of which a polymetal-lic orebody with a length of 360 m and a mean thickness of 9.11 m has been outlined by confirmation holes. Anomolies Ⅱ 2 Ⅱ 3 are about 1300 m long and 20-60 m wide within the scope of which a polymetallic orebody with a length of 870 m and maximum thickness(on the Earth's surface) of 21. 4 m has been outlined by confirmation holes. Moreover. there is a great induced polarization anomalous field to the southeast of the ore district. A polymetallic orebody has been found within the scope of this anomalous field by confirmation engineering, too.
