大横路钴铜矿床控矿因素及找矿标志

The ore-control factor and criteria for ore prospecting of the Dahenglu Co,Cu deposit

大横路钴铜矿床主要产于老岭群大栗子组第二岩性段内。其控矿因素主要有地层、褶皱和断裂、变质作用及岩浆活动。找矿标志主要为老岭群大栗子组含炭岩系、矿化蚀变(硅化、孔雀石化、褐铁矿化、黄铜矿化)、区域化探及土壤异常(Co、Cu、N、iPb、Zn、A g等组合异常)、老岭群大栗子组中的中基性脉岩等。

The orebody of the Dahenglu Co, Cu deposit mainly occurs m tne second lithozone of Dalizi Formation, I.aoling Group. The ore--control factor shows strata, fold, fracture, metamorphism and magmatic activities. The criteria for ore prospecting are mainly carbon- bearing rock series of the Dalizi Formation of Laoling Group, mineralization （silication, malachiteize, limoniteize and pyriteize;）, regional geochemical exploration and soil anomalies （ assemblage anomalies of Co, Cu, Ni, pb, Zn and Ag）, and intermediate basic vein rock.
