摘要: 至少一维尺度上小于100nm的矿物都属于纳米矿物的范畴,自然界中除了大量的人造纳米矿物之外,天然的纳米矿物分布也很广泛。随着透射电子显微镜(TEM)技术在地球科学中的应用,大量的天然纳米矿物在地壳表层和内部被发现。尤其是在矿田区域,与矿体相关的纳米矿物在各种介质中被发现,并且这些纳米矿物在矿床的研究中有着独特的作用。堆积型铝土矿床储量大,是铝土矿的重要来源。在堆积型铝土矿床中发育有大量的纳米矿物,矿石矿物也以纳米级晶体分布于矿床中,并且在纳米尺度上表现出结构和成分的变化,这些纳米矿物以及结构、成分的变化记录了铝土矿成矿过程的物理化学信息,为探究铝土矿的成因提供了独特的窗口。该综述总结了纳米矿物在研究堆积型铝土矿床中的优势,为研究堆积型铝土矿床的提供了新方法,为认识堆积型铝土矿的成因提供了新角度。

Abstract: Nanomineral is the mineral that is less than 100nm at least one dimension. Aside from the man-made nanominerals,there is a large number of natural nanominerals. With the increasing application of transmission electron microscopy(TEM)in earth science,a large number of natural nanominerals have been discovered in the surface and interior of the Earth. Especially in ore deposit region,nanominerals related to ore bodies are found in various media,and these nanominerals play a unique role in the research of ore deposits. The stacked bauxite deposit is an important source of bauxite because of its large reserve. There are a large number of nanominerals distributed in stacked bauxite deposit,and these ore nanominerals distributed in the deposit in the form of nanocrystals. In addition,the ore minerals in stacked bauxite deposit display changes of the structure and composition in nanoscale. The nanominerals as well as the changes of structure and composition in nanoscale can record the physical and chemical information of bauxite mineralization process,providing a unique window to explore the genesis of the stacked bauxite deposit. This review summarizes the advantages of nanominerals in the research on the stacked bauxite deposit,providing a new method and a new perspective for the understanding of the genesis of bauxite deposit.

Key words: nanomineral, stacked bauxite deposit, mineralization process, genesis of deposit
