铝土矿资源量估算新方法探讨

DISCUSSION OF A NEW METHOD FOR THE ESTIMATION OF BAUXITE RESOURCES

摘要: 偃龙铝土矿（洛阳部分）是豫西地区通过整装勘查新发现的大型铝土矿床.在偃龙铝土矿勘查工作的基础上，通过深入研究铝土矿在垂向和横向上存在矿物和矿产方面的相变特征，在铝土矿的矿体圈定和连接方面提出了铝土矿与其共生矿产在走向和倾向上呈渐变过渡关系的新认识.基于该认识确定了一种新的铝土矿资源量的估算方法.

Abstract: The Yanlong large-scale bauxite deposit is newly found in western Henan Province by the integrated exploration. Based on the exploration, with study of the phase transformation of bauxite mineral and ore, this paper proposes a new idea about the orebody delineation and connection, i.e. the bauxite ore and co-existing minerals show gradual transition in both strike and dip directions. This knowledge results in a more scientific and reasonable estimating method for bauxite resources.
