一、矿床地质概况本区超基性岩体侵入于晚石炭世地层中,被早二迭世地层所覆盖,属海西中期产物。由北而南可以分为三个岩体带。北带的分异岩相有:单輝輝橄岩相、二輝輝橄岩相和斜輝輝橄岩相。諸超基性岩,普遍遭受强烈的蛇紋岩化,橄欖石和輝石分別变成蛇紋石和絹石,深至地下600米处之岩石亦然。含矿超基性岩,主要由純橄欖岩及斜輝輝橄
I. Geological Profile of Deposits Ultramafic rocks in this area intrude into Late Carboniferous strata and are covered by Early Permian strata, belonging to the mid-Hercynian product. From north to south can be divided into three rock belt. The divisional facies in the north zone are: monopiper feldspathite, dihuan mafic facies, and mafic facies. All ultrabasic rocks generally experience intense serpentinization, with the olivine and pyroxenes becoming serpentine and serpentine, respectively, as deep as rock 600 meters underground. Ore-bearing ultrabasic rocks, mainly composed of dunite and diagonal Huihui
