西秦岭阳山金矿带控矿因素、找矿标志及深部成矿预测
Ore-controlling factors, prospecting criteria and deep metallogenic prognosis in Yangshan gold ore belt, West Qinling Mountain
摘要
Abstract
The Yangshan gold ore belt located in the west of Qinling Mountain tectonic belt is currently the largest independent gold deposit in China.The No.12 Gold Geological Party of CAPF discovered it in 1997,and so far,the gold resources have reached more than 380 t.In order to find out the metallogenic regularity and prospecting potential of the Yangshan gold deposit,the No.12 Gold Geological Party of CAPF carried out deep mineral investigation and study in the mining area.On the basis of previous studies and through the recent geological,geophysical exploration and indoor comprehensive study,the authors analyzed and summarized the ore-controlling factors and prospecting criteria of the Yangshan gold ore belt.Research shows that the NEE-trending and nearly EW-trending fracture systems in the area are distributed along the interlayer fold and weak surface of rock strata in the south limb of Getiaowan-Caopinliang anticlinorium.The ore deposits are obviously controlled by the main faults.On such a basis,the authors made use of the information quantity method to perform metallogenic prognosis,and delineated four ore-prospecting target areas at the depth of Anba area.The results provide guidance for the further exploration of mineral resources.关键词
