青海省都兰县柴湾多金属矿地质特征与找矿标志研究
|
摘要
研究区大地构造位置属于柴达木晚中生代—新生代断坳盆地(削减带)东段,断裂构造控制区内地层和岩浆岩的分布,形成较好的成矿环境。成矿围岩为石碳系大干沟组碳酸盐岩,含矿岩性主要为矽卡岩、大理岩及灰岩,属接触交代的矽卡岩型矿床,构造裂隙及节理是储矿的主要空间,是寻找较大矿体的有益地段。
The geotectonic location of the study area belongs to the eastern part of the Late Mesozoic-Cenozoic fault-breaking basin(cutting zone) in the Qaidam. The distribution of stratigraphic and magmatic rocks in the fault structure control area forms a good metallogenic environment. The ore-forming surrounding rock is the Carboniferous Dagangou Formation carbonate rock. The ore-bearing lithology is mainly skarn, marble and limestone. It belongs to the skarn type deposit with contact and metamorphism. The tectonic fracture and joint are the deposits. The main space is a good location for finding larger ore bodies.
