| 摘 要： | 河南嵩县纸房钼矿是在中元古界火山岩中顺层产出的钾长石英脉型钼矿，矿化石英脉呈似层状、透镜状密集平行排列，厚0.35～5.0 m，与围岩整合产出。矿化石英脉可以划分为3期，早期无矿石英脉呈致密块状，中期石英脉是钼矿化石英脉，晚期属于无矿化石英-碳酸盐细脉。地球化学研究显示成矿物质主要来自火山热液，成矿年龄与熊耳期火山喷发期后的时间一致。成矿流体成分、液相成分特征值及氢氧同位素分析表明，成矿流体属于在高温地质作用条件下形成中高温混合流体，流体包裹体显示为中高温热液沸腾和不混溶成矿，成矿压力为28×105 ～68×105 Pa，属于低压浅成火山机构热液充填成矿。

| Abstract: | Zhifang molybdenum deposit in Songxian County of Henan Province is a K-feldspar quartz-vein-typed deposit occurring along the strata of Middle Proterozoic volcanic rock.The stratiform-like and lenticular mineralized quartz veins,with a thickness ranging from 0.35 to 5.0 m,appear parallel and dense and have a conformable contact with enclosing rocks.The mineralized quartz veins can be classified into three stages.The early stage quartz veins without ore is compact and massive.The quartz veins of middle stage... |
