摘要: 通过钻探、浅井等工程控制和大量的样品分析结果表明，波罗芬高原铝土矿矿体赋存于第四系风化残坡积物中，矿床属红土型三水铝土矿，由玄武岩风化淋滤而成，埋藏标高760 m以上，高于侵蚀基准面.探明内蕴经济资源量（331）800×104 t；获总资源量约6000×104 t.通过对勘查工作的总结和分析，揭示了该类型矿床成因特点和赋存规律，并对找矿远景进行了预测.

Abstract: The bauxite deposit in Boloven Plateau is located in the southeast of Champasak Province, southern Laos. Drilling, trenching and analysis of samples show that the ore bodies, which occur in Quaternary weathering residual sediments, are lateritic type bauxite, formed by weathered and leached basalt. The burial depth is 760 m above sea level and above the base level of erosion. The proved reserve is about 8 million tons, with total reserves about 60 million tons. With analysis of the geological exploration result, the article introduces the genetic characteristics and occurrence regularity of the deposit, as well as prediction to the ore-searching prospects.
