| 摘 要： | 系统研究金平县白马寨铜镍硫化矿地质、矿床地球化学特征,初步认为该矿床形成于华力西期弧后盆地拉张的构造环境.并提出本矿床为幔源岩浆熔离-结晶分异,岩浆、含矿岩浆、富矿岩浆和矿浆依次脉冲式贯入成矿和成矿期后煌斑岩浆侵入破坏,并叠加成矿的矿床成因模式.从而,建立了本区铜镍矿床的成矿模型,并对该矿床深部及外围找矿提出建议. |

| Abstract: | Based on systemic studies of geology and geochemistry characteristics of Baimazhai Cu-Ni deposit in Jinping county, Yunnan province, it is suggested that the Baimazhai ore deposit was formed in Variscan post-arc extensional environment of continent margin. An ore-forming model with fractional crystallization of mantle-derived magma melt-crystal difference, magma, ore-bearing magma, ore-rich magma, ore-magma pulsed inrush in turn, post-mineralization lamprophyre magma intrusion and superposition mineralization has been proposed. Ore-forming model of the Cu-Ni deposit is established and exploration suggestions at the periphery and deep part of deposit are pointed out. |
| Keywords: | geochemistry ore-forming environment ore-forming model Baimazhai |
