坡一岩浆硫化物矿床赋矿岩石主要为华力西中期第一侵入次第二阶段纯橄榄岩、辉石橄榄岩、橄榄辉石岩、辉石岩.镍矿体主要分布于超基性岩体中部、底部.矿石类型以星散浸染状为主,次为稀疏浸染状、少量稠密浸染状、海绵陨铁状,半块状-块状、脉状.金属硫化物主要为镍黄铁矿、磁黄铁矿及黄铜矿,次为黄铁矿、白铁矿.通过对坡一岩浆硫化物矿床岩相学、岩石化学、稀土微量元素特征、成矿作用总结分析,初步探讨矿床成因.

The ore-bearing rock of Poyi magmatic sulfide deposit are mainly the dunite, pyroxene peridotite,olivine py-roxenite,pyroxenite of the second period of the first intrusive mid-Variscan.The nickel orebody mainly distributed in the middle and the bottom of the ultrabasic rocks.Ore types consist of scattered disseminated, followed by sparse disseminat-ed, a little of dense disseminated and sideronitic,semimassive-massive,vein-like.The sulfide mainly include pentlandite, pyrrhotite and chalcopyrite,pyrite and marcasite take second place.The genesis has been preliminary discussed after the analysis on the characteristic of petrography,petrochemistry,REE and trace element and mineralization of the Poyi mag-matic sulfide deposit.
