| 中文摘要: |
| 分布在东昆仑山南坡青海省大干沟地区的浩特洛哇组黑色岩系，属陆缘裂陷滨海-浅海相沉积的碎屑岩-碳酸盐岩建造，形成于缺氧环境。区内的大干沟钒钼矿床、大干沟口V-Mo-PGE矿床均赋存于浩特洛哇组（C2P1h）中，矿体均为层状、似层状，具层控特征。近年工作在大干沟口浩特洛哇组碳质板岩中发现了Mo、Au等元素的化探异常，通过少量的槽探及钻探工程控制钒钼矿体8个；钻孔ZK001、ZK701中均见Pd矿化，w（Pd）=0.03×10-6~0.16×10-6，达到伴生矿床工业开采品位。大干沟黑色岩系中伴生铂族元素的发现，给青海省柴南缘地区非传统类型的铂族元素矿床的找矿突破带了希望，与黑色岩系有关的V-Mo-PGE矿产找矿前景光明。 |
| 英文摘要: |
| Black rock series of Haoteluowa Fm in the Da Gangou area of Qinghai located in the southern slope of East Kunlun is the littoral-neritic clastic-carbonate rock rock formation deposited at continental margin rift under anaerobic environment. The Dagangou Vanadium molybdenum deposit and Dagangoukou V-Mo-PGE deposit are hosted by Haoteluowa Fm (C2P1h). Ore bodies are bedded or layered characteristic of stratobound ore bodies. In recent years, geochemical anomalies of elements such as Mo and Au have been found in carbonaceous slate of C2P1h, in Da Gangoukou area. Drill hole ZK001、ZK701 hit Pd mineralization (w(Pd)=0.03×10-6~0.16×10-6, the by-product mining grade). A few drilling and trenching have controlled 8 Vanadium molybdenum ore bodies. trenching and drilling engineering control 8 vanadium molybdenum ore bodies. PGE discovered in the black rock series will bring a bright future for the non-traditional PGE prospecting in south margin of Caidamu basin in Qonghai province and V-Mo-PGE prospecting here is potential. |
