摘　　要：喀斯特型铝土矿是我国铝土矿的最主要来源,占资源总量的90%以上,主要分布于华北克拉通和华南地块西南缘。近年来,作为一种战略性紧缺矿产,铝土矿的找矿勘查工作变得迫在眉睫。本文系统总结喀斯特型铝土矿的找矿预测成果,探索找矿预测方法最优组合,从而在找矿经验中进行归纳、总结。本文从地质、地球物理、地球化学、遥感以及地学大数据等多个方面分析并结合实例,全面梳理了我国喀斯特型铝土矿的找矿预测研究成果,认为地质和地球物理方法仍是目前中国喀斯特型铝土矿最主要的找矿预测手段。此外,分析了地球化学和遥感方法在寻找古喀斯特型铝土矿方面的局限性及其原因,指出未来展开地学大数据智能找矿的深远意义。Karst bauxite is the most important source of bauxite in China,accounting for more than 90%of the total resources,mainly distributed in the North China Craton and the southwest margin of the South China Block.In recent years,as a kind of strategic scarce mineral resource,the prospecting prediction of bauxite has become extremely urgent.This paper systematically summarizes the results of karst bauxite prospecting prediction and explores the optimal combination of prospecting prediction methods,so as to summarize the prospecting experience.By combing the examples and methods of geology,geophysics,geochemistry,remote sensing and artificial intelligence of geological big data to review the research results of karst bauxite prospecting and prediction in China,it is considered that geology and geophysics are still the most major methods for Chinese karstic bauxite prospecting prediction at present.In addition,the limitation of geochemical and remote sensing methods in searching for paleo-karst bauxite and their causes are analyzed,and the far-reaching significance of intelligent prospecting with geological big data is pointed out in the future.
