藏东斑岩铜矿带中的多霞松多矿床,是一个被第四系冲积物、坡积物和冰积物覆盖的大型斑岩铜矿.该矿床含金虽不高,但具有一定规模,可综合利用. 金主要产于矿床上部0～300米范围内的成矿花岗斑岩和含矿蚀变围岩中.花岗斑岩含金0.032～0.16克/吨;含金较好的围岩矿石中,金的品位为0.05～0.14克/吨.金主要赋存于黄铁矿和黄铜矿中、少量呈自然金产出. 矿床位于一条25公里长的小河源头之下约2公里处,海拔4500米;河口海拔高度3700米.地貌上,小河流域属强烈侵蚀的高山地形. 在地质普查过程中,沿矿床围岩蚀变圈以外的21
The Duoxiandongduo deposit in the possession of the Qidong porphyry copper belt is a large porphyry copper deposit covered by Quaternary alluvial deposits, alluvial deposits and glacial deposits. Although the gold content of the deposit is not high, Scale, and can be comprehensively used.Gold is mainly produced in the ore-bearing granite porphyry and ore-bearing altered rocks within the range of 0 ~ 300 meters in the upper part of the deposit.The granite porphyry contains 0.032-1.16 g / t gold, Good grade rock ore, the gold grade of 0.05 ~ 0.14 g / t.Gold mainly occurs in pyrite and chalcopyrite, a small amount of natural gold output.The deposit is located in a 25 km long stream source About 2 kilometers above sea level, 4500 meters above sea level; estuary height of 3700 meters .On the topography, the small river basin is strongly eroded alpine terrain .In geological survey process, along the rock wall outside the alteration circle 21
