全球红土型镍矿床具有明显的时空分布规律,红土型镍矿体则具有明显的垂向分带规律。红土型镍矿化强度明显受成矿母岩成分(包括镍含量、岩石地球化学成分、矿物成分)、气候、地形地貌、水文地质、构造地质、成矿时间长短及风化壳成熟度的影响和控制。红土型镍矿的矿床类型主要受气候、大地构造背景、构造隆升状态控制,并受地形地貌、排水条件、成矿母岩岩性及其蛇纹石化程度影响。

The global lateritic nickel ore deposits have distinct temporal and spatial distribution regularity, and the lateritic nickel ore bodies are characterized by apparent vertical zoning. The intensity of lateritic nickel mineralization is obviously influenced and controlled by the components of ore-forming parent rock (such as nickel content and lithogeochemical and mineral composition), climate, topography, hydrogeology, structural geology, duration of ore-forming process, and maturity of the weathering crust. Types of lateritic nickel ore deposits are mainly controlled by climate, tectonic setting and the state of structural uplift and also influenced by topography, drainage condition, lithology of ore-forming parent rock and its serpentinization.
