| 摘 要： | 东南亚地区红土型镍矿分布较广,成矿地质条件优越。该类矿床产于超基性岩带顶部红土型风化壳内,矿石多为含镍的褐铁矿化黏土,其产出规模、分布范围和品位高低与原岩类型、气候变化、地形地貌和构造条件关系密切。成矿物质主要来源于超基性岩体,是镁铁质-超镁铁质岩体风化-淋滤-淀积的产物,矿石的矿物组分与风化土的矿物组分大体一致,属黏土硅酸盐镍矿床。本文在收集前人资料的基础上,系统地阐述了矿床区域地质背景、矿床地质特征及成矿分布规律初步研究,总结出了该类矿区找矿标志及成矿规律,对寻找红土型镍矿床具有一定的指导作用。

| Abstract: | Laterite nickel ore has a wide distribution in southeast Asia area and the geological condition of its mineralization is superior, the deposit is found in the belt of ultrabasic rock, inside the top of the laterite weathering crust, most of which is ferritization clay containing nickel, its production scale, distribution range and grade of ore level are closely related to the original rock types, climate changes, topography and structure conditions. The main source of mineralization materials is from ultrabasic rock mass, which is the result of maifc, ultramaifc rock mass weathering, leaching and sedimentation. Mineral component of the ore is general accord with that of the saprolite, which is subordinated to clay silicate nickel deposit. On the basis of predecessors’ data, the authors systematically discuss regional geological background of the ore deposit, geological features and the preliminary research of distribution regularities, summarize the ore prospecting criteria and metallogenic regularities, which has guiding role to discover laterite nickel ore. |
