摘要
都兰县达日龙洼多金属矿成矿区处于柴达木盆地南缘,东昆仑造山带北侧,属于祁曼塔格—都兰华力西期铁、钴、铜、铅、锌、锡、硅灰石(锑、铋)成矿带。本文在前期勘查工作的基础上,介绍了区域地质背景,矿区成矿地质背景,从地层、构造、岩浆岩、矿体特征及矿石特征等方面介绍矿区矿床地质特征,初步论述了成矿时代和矿床成因,总体认为矿区断裂构造发育,岩浆活动强烈,具有较好的成矿地质条件;氧化标志、蚀变标志及构造标志等是区内找矿的主要指示标志;通过对以往勘查成果综合分析认为该区具有较大的找矿潜力。
The Darilongwa polymetallic deposit in Dulan County is located on the southern edge of the Qaidam Basin,north of the East Kunlun orogenic belt,and belongs to the Qimantag Dulan Hualixi period iron,cobalt,copper,lead,zinc,tin,and wollastonite(antimony,bismuth)mineralization belt.On the basis of preliminary exploration work,this article introduces the regional geological background and the mineralization geological background of the mining area.It introduces the geological characteristics of the deposit in the mining area from the aspects of stratigraphy,structure,magmatic rocks,ore body characteristics,and ore characteristics.It preliminarily discusses the mineralization age and genesis of the deposit.Overall,it is believed that the mining area has developed fault structures,strong magmatic activity,and good mineralization geological conditions;Oxidation markers,alteration markers,and structural markers are the main indicators for mineral exploration in the area;Through comprehensive analysis of previous exploration results,it is believed that this area has great potential for mineral exploration.
