一、矿区地质概况及地球化学工作依据所述岩体北东延伸,南东倾,长5.5公里,宽0.3-0.4公里,面积2平方公里;主要由蛇纹石化的斜方辉橄岩组成,其次为异剥橄榄岩、含辉纯橄岩,后期辉长岩、辉石岩发育.矿体主要分布于岩体中段至北东端,赋矿岩相为斜方辉橄岩,矿体成群成带出现,矿石为致密块状,中-粗粒,矿石品位高,质量好,铬铁比高.矿体明显受裂隙控制.例如517矿带长480米,宽1-2米,矿体沿裂隙分布,裂隙中有紫
I. Geological Overview and Geochemical Work of the Mining Area According to the extension of the north east of the rock mass, the mining area is 5.5 km long and 0.3-0.4 km wide and covers an area of 2 km 2. It is mainly composed of serpentinian orthopyroxene, Followed by the dextral peridotite, dichroic dunite, late gabbro and pyroxenite.The ore bodies are mainly distributed in the middle part of the rock mass to the north east end, the ore facies is orthopyroxene and the orebody is For example, the ore body of 517 is 480 meters long and 1-2 meters wide, and the ore body is dense and massive with medium-coarse grain, high ore grade, good quality and high ratio of ferrochrome. Body distribution along the cracks, cracks in the purple
