务川大竹园铝土矿分布于黔中-渝南铝土矿成矿带的北部，成矿地质条件较好。本文通过大竹园矿区系统采集样品微量元素分析结果，与全球地壳丰度、中国大陆地壳丰度及山西铝土矿进行分析对比，探讨微量元素在平面上及纵向上的分布特征及其变化规律，分析其综合利用可能性。研究表明，微量元素在向斜两翼平面上的没有明显变化特征，而各元素在各类型岩（矿）石中有一定的分布规律，发现Li、Be、Sc、Ca、Zr、Nb等“三稀”元素达到了综合利用价值，这对下一步铝土矿综合勘查、合理开发提供了一定的理论依据，具有现实的指导意义。

Dazhuyuan bauxite deposit in Wuchuan located in the north of central Guizhou - south Chongqing bauxite belt, the metallogenic condition is good. By comparison of the analytic results of collected trace elements in Dazhuyuan area with global crustal abundance, crustal abundance of China and bauxite de- posit in Shanxi, the distribution characteristics and its change regulation of trace elements on plane and verti- cal are discussed, its probability of comprehensible utilization is studied. The study shows that ~ere is no ob- vious change on the both sides plane of syncline, but each element has some regulation in each ore, it' s found Li, Be, Sc, Ga, Zr, Nb and other' Three Rare Element' have reached the utility value, it supports some the- ory accordance for comprehensible exploration and reasonable utilization of bauxite deposit and has practical guidance significance.
