地质概况金宝山含铂超基性岩体位于滇中台拗的西南缘,红河深大断裂东北侧。岩体受次一级层间裂隙构造控制。侵入于下泥盆统下段的长石砂岩和板岩中。由于礼社江河水及其两侧沟谷流水的侵蚀和断层的破坏,使其出露于礼社江的两岸。岩体的岩石类型以杆榄岩为主,其中一号岩体分异较好。中部偏基性,为辉橄岩相带,上、下部及东、西两侧均为橄榄岩相带环绕。边部有零星分布的橄辉岩及辉石岩。经岩石化学分析,含铂岩体为铁质超基性岩。镁铁比值与铂钯矿化略显正消长关系。随着基性程度的增加,铂钯矿化相对变好。超基性岩受到强烈的蛇纹石化、次闪石化、绿泥石化和滑石化等蚀变作用。橄榄石多变成了蛇纹石。
Geological Survey Jinbaoshan platinum-bearing ultramafic rock is located in the southwestern margin of the Central Taiwan Stubbs, the northeastern Red River deep fault. The rock mass is controlled by sub-level interlaminar fracture structure. Intruded into the lower Devonian feldspar sandstone and slate. As a result of the Eritrean River and the water erosion on both sides of the valley and the destruction of the fault, it was exposed at both sides of the Risha Shejiang. The rock type of the rock is dominated by the kyanite, one of which is well differentiated. Central partial basaltic, as the mafic facies belt, upper and lower and east and west sides are peridotite facies belt around. The edge of sporadic distribution of olive rock and pyroxene. After petrochemical analysis, the platinum-bearing rock mass is an ultramafic rock of iron. Magnesite-iron ratio and platinum-palladium mineralization slightly positive correlation. With the increase of the basicity, platinum-palladium mineralization is relatively better. Ultrabasic rocks are strongly altered by serpentinization, sub-lithic petrification, chloritization and talcification. Olivine has become a serpentine.
