| 介绍拉丁美洲铝土矿资源概况、地质特征及成因类型。拉丁美洲铝土矿资源主要分在巴西、苏里南、牙买加、圭亚那、委内瑞拉等国家，储量为60.3×108t，占世界铝土矿总储量的21.54%。巴西为拉丁美洲最大的铝土矿生产国和出口国。拉丁美洲铝土矿成因类型主要为红土型和岩溶型2种，主要的铝土矿矿山有45座。牙买加岛弧、圭亚那地盾、中巴西地盾、圣弗朗西斯科地盾为4个铝土矿勘查开发潜力区。 |

| Abstract: |
| This paper emphatically describes the general situation, geological characteristics and genetic types of bauxite resources in Latin America. The bauxite resources of Latin American are mainly distributed in Brazil, Suriname, Jamaica, Guyana and Venezuela, and the reserves have reached 6.03 billion tons which account for 21.54% of the world's bauxite total reserves. Brazil is the largest bauxite producer and export country in Latin America. The genetic types of Latin American bauxite include lateritic type and karst type. There are 45 major bauxite mines in Latin America. The Jamaica island arc, Guyana shield, middle Brazil shield and San Francisco shield are the major bauxite resources potential areas for exploration and development in Latin America. |
