摘要: 以三门峡尖草地铝土矿床为对象，在研究矿床地质特征的基础上，分析了成矿物质来源、控矿因素，并刻画了成矿演化模式.三门峡尖草地铝土矿床赋矿层位为本溪组，是在沉积间断面、沉积古地理、古构造等多个条件的耦合作用下形成的.该地层后期抬升遭受剥蚀，再沉积形成局部堆积型的铝土矿床.其成矿演化模式在豫西地区具有典型找矿意义.

Abstract: Based on the geological characteristics of Jiancaodi bauxite deposit in Sanmenxia, the ore-forming material sources, ore-controlling factors and metallogenic evolution model are analyzed. The Benxi Formation, as the ore-bearing layer of the deposit, was formed under the coupling processes of sedimentary discontinuity, sedimentary paleogeography and paleostructure, followed by uplift, denudation and local accumulation. Its metallogenic evolution model has typical prospecting significance in western Henan.
