【摘要】 综述了国内外自然铝的发现与研究史;自然铝的物理性质和颗粒形态、元素组成及含量、晶体结构参数等特征;自然铝的成因模式。自然铝主要见于老的火山和热液矿石中,或现代和中—新生代的海底活动构造带(如转换断层、中央海隆以及弧后扩张中心)的海洋沉积物中,有地幔碳热还原、海底热液内生和陆地表生置换等3种成因模式。更多还原

【Abstract】 The paper reviewed advances on native aluminium research, including firstly process of finding and studying native aluminium , secondly physical property and morphology of metallic aluminium particles and their chemical composition,as well as crystal data, finally the models of the formation of native aluminium.In the geological environment native aluminium is usually found only in ancient volcanic rocks and hydrothermal ores, or in Recent and MesoCenozoic ocean sediments of the active tectonic regions of the ocean floor, including zones of transform faults,midocean ridges and backarc spreading centers. As a result of an accessory mineral involved mantle and high hydrothermal activity, there are three models of the formation of native aluminium,such as carbon deoxidization in the high temperature environment, endogenous processes of high hydrothermal activity in the submarine hydrothermal fluids,element replacement amond Al,S,K,Na.更多还原
