德尔尼大型钴铜矿床是一个以海底喷流-沉积成矿为主体,以后期叠加成矿为特色的复合成矿作用的矿床。其叠加成矿作用,则以钴矿(化)体的“套鞋状”产出和磁黄铁矿的“薄层外壳”为标志,以赋矿超基性岩与工业矿体接触处发生的蚀变作用、星点状磁铁矿的消失或净化,以及镍元素带入为支撑点体现出来的,它昭示了超基性岩体在叠加成矿过程中对德尔尼矿床成矿作用的某种贡献。
The Delni Ni-Co-Cu deposit is a deposit characterized by submarine jet-sedimentary mineralization and post-superimposed mineralization. Its superposition of mineralization, the cobalt ore body (body) “overshoe ” output and pyrite “thin shell ” as a symbol, to ore-handling ultrabasic rock and industrial ore body The alteration at the contact, the disappearance or purification of the apical magnetite, and the nickel element carry-over are the supporting points. It shows that the ultramafic rock mass Some contribution to the role of ore.
