河南省栾川县石宝沟钼矿矿床地质特征及成因探讨

THE GEOLOGICAL FEATURES AND GENETIC ANALYSIS OF SHIBAOGOU MOLYBDENITE DEPOSIT IN LUANCHUAN COUNTY,HENAN PROVINCE

栾川县石宝沟钼矿床位于华北地台南缘与秦岭褶皱系相交部位,在研究区域地质、矿区地质基础上,重点对矿床地质特征进行了研究,认为矿体形态、产状受花岗斑岩岩体形态、围岩岩性、构造控制较为明显,通过对矿床成因的分析,说明石宝沟钼矿床在空间上、时间上、成因上均与深部花岗岩浆有关,矿床成因应为斑岩—矽卡岩型,对以后寻找类似矿床有一定的借鉴意义。

Shibaogou molybdenite deposit from Luanchuan country is located in the intersection between south mar-gin of North China and Qinling fold system.Based on the research of regional and mineral geology,this article puts a special stress upon the deposit’s geological features research;we think that morphology and occurrence of the de-posit are clearly controlled by the morphology of granite -porphyry,lithological characters and contracture of the surrounding rock.Through preliminary analysis on the causes of the deposit,it shows that Shibaogou molybdenite deposit has a close relationship with the deep granitic magma,no matter on the cause of space,time and reasons;the ore genesis of the deposit could be porphyry-skarn,which provides certain significance on exploring such simi-lar deposit.
