青海多格日铜多金属矿床地质特征及找矿潜力分析

文章研究了青海省都兰县多格日矿区地层、构造、岩浆岩的分布情况及其与成矿的关系,区内地层主要为奥陶-志留系滩间山群c岩组和上三叠统鄂拉山组。区内多格日矿点的矿产为铜、铅,矿体均产于北东向逆断层下盘围岩节理发育的部位,矿体倾向均为南东;物探工作的开展,获取了区内岩石的物性资料,总结了区内地球物理特征和地球化学特征,研究表明磁法工作对区内开展构造研究和岩性填图具有重要指示意义。此次工作在区内共发现并圈定矿体8条,其中4条盲矿体。研究为实际工程勘探提供了理论依据。

Analysis on Geological Characteristics and Metallogenic Potential of the Cu-polymetallic Deposits of Duogere Mining Area in Dulan, Qinghai

This paper studies the distribution of strata, tectonics and magmatic rocks and their relationship with mineralization in Duogeri mining area of Dulan County, Qinghai Province. The main strata are is Ordovician- Silurian Tanjianshan Group C Rocks and Late Triassic Eilashan Formation. The minerals of the Duoge mining spot are copper and lead, and the ore bodies in this area, which are all existing in the joints of the footwall surrounding rocks of the NE-trending reverse fault. The ore body tends to be in the southeast. By geophysical exploration, the physical properties of the inner rocks have been studied and also the geophysical and geochemical characteristics of the area have been summerized. The study shows that the magnetic method has important guiding significance for the tectonic study and lithology mapping work in the area. In this paper, 8 ore bodies were found and delineated in the area, including 4 blind ore bodies. The study provides a theoretical basis for practical engineering exploration.
