摘要
阿尔泰地区存在 5条与深大断裂有关的基性、超基性岩带 ,是铜镍硫化物矿床产出的有利地段 ,其中喀拉通克铜镍矿是我国大型铜镍矿之一。通过对成矿必要条件的深入研究 ,得出深大断裂及其次级断裂控制了岩体的产出 ,北北西向断裂叠加北西向断裂控制了矿体的产出 ;成矿充分条件是基性、超基性岩体 ,总结了岩体含矿性的评价指标。结合重磁及地化资料 ,在喀拉通克铜镍矿的成矿模式基础上 ,建立了区域综合信息找矿模型 ,进行成矿预测 ,圈定靶区 9处。
There exits 5 rock zones of basic and ultrabasic related with deep faults,which are favorable condition for Cu-Ni ore-bearing.The large deposit,Kalatongke Cu-Ni ore,occurs in one of these rock zones.The metallogenetic necessary condition is deep fault,which controls the basic and ultrabasic rock body of bearing ore, and the connecting fractures between NNW and NW direction faults controls the ore-body;The metallogenetic ample condition is basic and ultrabasic rock body,and the criteria of body’s ore-bearing ability is provided.On base the metallogenetic model of Kelatongke Cu-Ni deposit, a regional comprehensice information ore-searching model of Cu-Ni ore is set up, considered for geological,geophysical and geochemical data.At last,9 targets of regional metallogenetic prediction are given.
