摘　　要：基于201个浅井剖面的Ni元素分析,对印尼苏拉威西岛kolonodale红土型镍矿区内红土剖面的垂向品位变化规律展开了研究。研究结果表明,红土镍矿的形成受地层、构造、环境、水文及风化的综合影响,从中得出极具代表性的剖面类型,为以后的红土镍矿地质工作提供对比。Based on the analysis of Ni element in 201 shallow well profiles,the vertical grade variation law of laterite profile in kolonodale laterite nickel deposit area,Sulawesi island,Indonesia,is studied in this paper.The research results show that the formation of laterite nickel deposit is affected by strata,structure,environment,hydrology and weathering,and representative section types are obtained,which can provide a comparison for the geological work of laterite nickel mine in the future.
