青海省都兰白石崖M14区多金属矿地质特征及找矿方向

Geological Characteristics and Prospecting Direction of Polymetallic Deposits in Baishiya M14 Area, Dulan, Qinghai province

研究区大地构造位于南邻东昆中新元古代—早古生代缝合带,成矿条件较好。白石崖M14铁多金属矿为接触交代型矽卡岩矿床。对矿区地层岩性、矿体形态、矿石类型、矿物组成、围岩蚀变等特征进行了详细总结,分析区内矿床的控矿因素和矿床成因,希望对今后的地质勘查工作有一定指导作用。

Geotectonics in the study area is located in the Mesoproterozoic-Early Paleozoic suture zone adjacent to East Kunming in the south,and the metallogenic conditions are good.Baishiya M14 iron polymetallic deposit is a contact metasomatic skarn deposit.The characteristics of strata,lithology,ore body shape,ore type,mineral composition and wall rock alteration in the mining area are summarized in detail.The ore-controlling factors and genesis of the deposits in the area are analyzed.It is hoped that this paper will play a guiding role in future geological exploration.
