陕西省宁陕县杨泗庙-懒板凳一带钨钼多金属矿矿体特征及找矿标志

Characteristics and prospecting indicators of tungsten molybdenum polymetallic deposits in Yangsi Temple Lazy Bench area,Ningshan County,Shaanxi Province

宁陕县杨泗庙—镇安懒板凳一带的钨矿床整体受晚古生代碳酸盐岩沉积-海西期变质建造控制,成矿流体和成矿物质来源于燕山期花岗岩岩浆,懒板凳岩体为宁陕县杨泗庙-镇安懒板凳地区成矿提供有利的热动力条件和介质条件;石瓮子组为区内有利成矿地层;懒板凳岩体外围石瓮子组碳酸盐岩地层形成的矽卡岩带,是矽卡岩型钨矿赋存的有利层位。

The tungsten deposit in the Yangsi Temple Zhen'an Laoban area of Ningshan County is generally controlled by Late Paleozoic carbonate rock sedimentation and Hercynian metamorphic construction.The ore-forming fluid and material come from Yanshanian granite magma,and the Laoban rock body provides favorable thermodynamic and medium conditions for mineralization in the Yangsi Temple Zhen'an Laoban area of Ningshan County;The Shiwengzi Formation is a favorable mineralization stratum in the area;The skarn belt formed by the carbonate strata of the Shiwengzi Formation outside the body of the Lazy Bench Rock is a favorable layer for the occurrence of skarn type tungsten deposits.
