西秦岭柏家庄岩体钨矿成矿地质背景及化探异常特征

Geological Background and Geochemical Anomaly Characteristics of the Tungsten Deposit in the Baijiazhuang Rock Mass of the West Qinling Mountains

柏家庄岩体位于西秦岭寨上-马坞金矿集区,成矿地质条件优越,化探W元素富集明显,异常强度高,规模大,与Sn、Bi、Mo元素套合性好,是寻找钨、锡多金属的有利靶区。在充分收集已有的基础上,开展地质、1:1万土壤测量和探槽工程揭露查证,新发现钨矿体2条、铜矿化体1条,以期为区内找矿突破提供方向。

The Baijiazhuang rock mass is located in the Zhaishang Mawu gold deposit concentration area of the West Qinling Mountains,with superior ore-forming geological conditions,obvious enrichment of W elements in geochemical exploration,high anomaly intensity,and large scale.It has good compatibility with Sn,Bi,and Mo elements and is a favorable target area for searching for tungsten and tin polymetallic elements.On the basis of fully collecting existing data,geological and 1:10000 soil surveys were carried out,as well as excavation and verification of trench engineering.Two new tungsten ore bodies and one copper mineralized body were discovered,in order to provide direction for breakthroughs in ore exploration in the area.
