| 摘 要： | 河南省栾川县脉石英矿体赋存在长城系熊耳群火山岩地层内,总体呈近东西向和北西西向展布,矿石为致密块状,主要矿物组成为石英集合体,新鲜面为乳白色、灰白色、白色,半透明状,SiO2平均含量超过97％.脉石英矿体的分布表明该区脉石英的形成主要受构造和岩浆活动控制,大多数脉石英矿围绕构造穹隆外缘的裂隙分布,栾川县这类构造穹隆短轴...

| Abstract: | Vein quartz deposits in Luanchuan County,Henan,hosted in Changchengian Xiong’er Group volcanic rock are dominated by east-west trending with minor south-north trending.The ore shows dense massive texture and dominant minerals is quartz aggregate.Fresh ore is milk white,grey and translucent.The average SiO2 content of ore excess 97%.The distribution of vein quartz deposits in Luanchuan County suggests that they are controlled by tectonic and hydrothermal activities in this region.Most deposits occurred along the ringed steep-dipping fractures surrounding the outer margin of structural vaults,so well-developed vault brachy-anticline structures in Luanchuan pridicts good propects for vein quartz deposits in Luanchuan. |
