摘　　要：岩坪铝土矿区位于渝南―黔北成矿带之务川―正安―道真铝土矿矿集区北部,大塘向斜南段西翼扬起端。本文根据矿区南矿段见矿工程控制的矿系厚度与矿体厚度的统计数据,结合与东部邻区新民矿床北矿段深部含矿岩系厚度、矿体厚度对比,获知含矿岩系厚度与矿体厚度及矿石质量呈正相关;找矿勘查表明:应用含矿系厚度稳定性、浅部矿体厚度变化趋势,以及矿石类型分布规律作为找矿标志,以此反演岩相古地理环境对找矿工作更加有利。Yanping bauxite deposit is located in the north of Wu-Zheng-Dao (Wuchuan-Zheng’an-Daozhen) bauxite ore-concentrated area in southern Chongqing-northern Guizhou metallogenetic belt,and the rising end of west limb of south section of Datang syncline.According to the data of ore discovery engineering con-trol,thickness of ore-bearing rock series and bauxite orebodies in south section of the deposit and the com-parison with the thickness of ore-bearing rock series and ore-bodies in deep part of north section of Xinmin deposit in the east,this paper believed that the thickness of ore-bearing rock series was positively correlated to the quality of ores;the prospection verified that:prospection works benefited a lot from the lithofacies pa-leographic environment which was inversed by application of the stability of thickness of ore-bearing rock se-ries and the changing trend of thickness of ore-bodies in superficial part and usage of distribution regularity of ore types as prospecting clues.
