摘　　要：河南岳村铝土矿床含矿层位为上石炭统本溪组,赋存于奥陶系碳酸盐岩古风化剥蚀面上,为一大型铝土矿床。本文针对该矿床深部铝土矿的控矿因素及找矿方向研究空白,通过查阅前人研究成果、分析矿区大量基础资料,提出岳村铝土矿床是在特定的时期、古地形、古构造、古气候、成矿作用等因素综合作用下而形成,总结其找矿标志及方向,提出有针对性的找矿建议。The Yuecun bauxite deposit occurred in the paleo weathered erosion surface of ordovician carbonate rock,the ore-bearing horizon was the Benxi Group strata of Lower Carboniferous series.The mine was a large fireclay deposit.This is a research gap from ore-controlling factors and prospecting direction of bauxite,especially deep bauxite in this area.Summarize the previous research results and basic data of mining area.The study shows that Yuecun bauxite was formed under the comprehensive action of palaeotopography,palaeostructure,paleoclimate mineralization and other factors in a specific period.The prospecting criteria and methods are sum-marized.It was suggested that attention should be paid to the negative terrain areas such as karst rock pits or bucket controlled by microfacies in supratidal zone of the edge of ancient land(island)in the future prospecting.
