新安县石寺—北冶铝土矿区地层展布大多为北东走向,具西北端隆起、向东南方向呈“一面坡”倾斜的特征。矿体受地层控制,总体产状与地层产状一致,形态呈似层状(东部)、洼斗状(中西部)产出;文章通过深入剖析矿区内56个铝土矿石样品的化验分析结果及11个岩、矿石薄片鉴定结果,详细归纳总结了该矿区的矿石特征及富集规律,为今后在矿区找矿与勘探提供理论依据。 Most of the stratigraphic distributions of the Shi’shi-Bei’er bauxite mine in Xin’an County are mostly north-eastward with the uplift of the northwestern tip and the feature of “slope” tilting to the southeast. The orebodies are controlled by stratum. The overall occurrence is consistent with that of the stratum. The shape of the orebodies is stratified (east) and waled (central and western). By analyzing the laboratory analysis of 56 bauxite samples in the mine area, Results and 11 rock and ore thin slices identification results summarized the ore characteristics and enrichment law in the mining area in detail for the future prospecting in the mining area to provide a theoretical basis.
