摘　　要：中国是世界上最大的铝生产和消费国,铝土矿又是生产铝的主要原料。因此,寻找铝土矿资源对于发展我国的铝工业具有重要意义。铝土矿分为红土型、古红土型和堆积型三大类,国外铝土矿多为红土型,而中国却以古红土型为主,目前只有少数几个小型红土型铝土矿。红土型铝土矿冶炼流程简单、能耗低,而古红土型铝土矿冶炼能耗大、成本高。本文参考国外红土型铝土矿资料,总结国外大型矿床的构造、气候、地貌、成矿母岩和成矿时间等特点。分析我国特别是南方地区的成矿条件,找出利于成矿的区域,绘制出中国南方红土型铝土矿的找矿远景区。并探讨红土型铝土矿的找矿方法,为找矿勘探提供服务。China is the largest aluminum producer and consumer in the world, and bauxite is the main raw material for alumina production. SO searching for bauxite resources is great significance for the development of aluminum industry in China. Bauxite is divided into laterlte - type, paleo - laterite -type and karst accumulation - type, mostly laterite - type abroad and paleo - laterite - type in China, only little small laterite bauxite in our country. The refining process is simple, low energy consumption for laterite bauxite and contrary to paleo - laterite bauxite. The information of the ]ateritic bauxite is referred to, and the characteristics with tectonics, climate, geomorphology, and the host rock and metallogenetic epoch are summed up in foreign country in this pa- per. After analysis of the metallogenetic conditians, the areas which conducive to metallogenetic in China are found out, and Southern China lateritics bauxite potential prospective areas are mapped out. The methods of laterite bauxite prospecting are discussed to provide some services for bauxite prospec-ting and exploration.
