巴颜喀拉山地区砂金资源丰富,采金历史悠久,已往的开采多限于玛曲—玛多以北地区,据史料记载估计采金量不少于32万两。1983—1986年采金者近十万人次,年产金量万余两。该区现为新开辟的砂金地质工作区,已查明中型矿床3处、矿点12处、矿化点和群采点数十处,已探明储量占全省砂金总储量的54.55%。成矿预测表明,该区砂金资源潜力较大,具有良好的找矿前景。本文拟对区内砂金的区域性成矿条件进行初步分析,供参考利用。
Bayan Harlem region is rich in gold resources, gold mining has a long history, the previous exploitation is mostly limited to Maqu-Maduo north region, according to historical records is estimated that the amount of gold mining not less than 320,000. From 1983 to 1986 nearly 100,000 gold miners, with an annual output of more than 10,000 two. The area is now a newly-opened sand gold geological work area. It has ascertained that there are 3 medium-sized deposits, 12 ore points, dozens of mineralization points and group mining points, and the proven reserves account for 54.55% of the total gold reserves in the province. Metallogenic prediction shows that there is a great potential for gold resources in this area and a good prospecting prospect. This article intends to make a preliminary analysis on the regional metallogenic conditions of the gold deposits in the area for reference.
