寿山火山盆地雕刻用叶蜡石矿成矿地质条件及找矿靶区预测

Metallogenic Geological Conditions and Prospecting Target Prediction of Carved Pyrophyllite Ore in Shoushan Volcanic Basin

根据寿山早白垩世火山喷发盆地内典型雕刻用叶蜡石矿成矿地质条件、火山构造、贮矿部位以及蚀变矿物组合特征综合分析,认为寿山火山盆地雕刻用叶蜡石矿主要控制因素以火山构造为主体,叠加区域断裂构造。寿山火山盆地发育17个Ⅴ级火山群或破火山组合体控制了叶蜡石矿的产出,Ⅴ级复活火山机构控制了雕刻用叶蜡石成矿的地段;并提出找矿标志,初步圈定找矿靶区。

According to the comprehensive analysis of the ore-forming geological conditions,volcanic structure,ore storage site and the characteristics of altered mineral assemblage in the early cretaceous volcanic eruption basin of Shoushan,it is believed that the main controlling factors of caved pyrophyllite ore in shoushan volcanic basin are volcanic structure and superimposed regional fault structure.Shou volcanic basin development level 17Ⅴvolcanoes or volcanic combination controlling the pyrophyllite ore output,Ⅴlevel raised volcanic institutions controlling the carved pyrophyllite ore area,and puts forward the prospecting mark and preliminarily delineates the ore-prospecting target area.
