| 摘 要： | 河南省夜长坪钼矿床是东秦岭钼成矿带中的大型斑岩-夕卡岩型高-中温热液隐伏钼矿床。钼矿床赋存于官道口群龙家园组中,受燕山期中酸性浅成-超浅成花岗斑岩体的控制,产于夕卡岩接触带中,矿层呈叠层透镜状,中部上凸,向四周及深部倾斜、延伸。作者利用Micromine软件建立了矿体的三维立体模型,分析了矿体以及矿石类型三维空间分布规律。利用矿区地质勘查成果,通过常量元素、微量元素、稀土元素、流体包裹体、同位素测年资料的研究,确定矿床成岩、成矿时代,分析矿床成因。

| Abstract: | Yechangping molybdenum deposit is porphyry-skarn type mesothermal molybdenum deposit in East Qinling molybdenum metallogenic belt.The Mo deposit is controlled by Longjiayuan Fm.dolomite of Guandaokou Group and hided acid hypabyssal granitic-porphyry intruding into Yechangping anticline in Yanshan period.Ore bed was in the contact zone of skarn,stacked lenticular,central convex and tilted extending to the surrounding.Taking use of Micromine software,the writer set up 3-D model of the orebodies and then analysed the spatial distribution rules of orebodies and ore types.Based on the analysis of major elements,trace elements and REE,and geochemical characteristics of fluid inclusion,metallogenic model of the Yechangping Mo deposit was established in combination with isotopic dating to determine era of rock-form and ore-form. |
