摘要
玉古拉矿区处于冈瓦纳北缘,晚古生代-中生代冈底斯-喜马拉雅构造区中段北部,矿区内出露地层主要有二叠系下拉组(P2x)灰岩;下白垩系卧荣沟组(K1w)辉石安山岩、安山岩、流纹岩、流纹质熔结凝灰岩,局部偶夹有少量中细粒石英砂岩;上白垩系拉江山组(K1l)零星分布。矿体主要赋存于超基性岩中,近东西向展布。初步查明玉古拉镍矿的地质特征,查明玉古拉铁镍矿为基性-超基性岩型矿床。
YuGula mining areas is located in the north Margin of Gondwana, late Paleozoic-Mesozoic Gangdese- the middle of North Himalayas tectonic province, which exposed layer mainly includes Permian system P2x limestone, lower Cretaceous K1ω pyroxene andesite, andesite, rhyolite, trad welded tuff, and a bit Fine-grained quartz sandstone, upper Cretaceous K1l distributed sporadically. Ore produced in the ultra basic rock, diverge in East and West. The main purpose is to find Geological feature of nickel ore and basic-uhrabasic deposit of awaruite in YuGula.
