河南禹州铝土矿"三位一体"找矿模型及资源潜力

禹州铝土矿位于华北地台西南部的嵩箕台隆南缘，嵩箕铝土矿成矿区.该区具有明显的地台型基底和盖层二元结构，基底由古元古界嵩山岩群构成，盖层系较标准的地台型沉积，由一套古生界海相碎屑岩-碳酸盐岩建造，古生界海陆交互相含铝、煤建造和陆相碎屑岩建造组成.通过对该区铝土矿控矿因素及找矿标志分析，建立了该区铝土矿找矿模型，并对该区铝土矿的资源潜力进行了评价.

PROSPECTING MODEL AND RESOURCES POTENTIAL OF YUZHOU BAUXITE DEPOSIT,HENAN PROVINCE

The Yuzhou bauxite deposit is located in the Songji bauxite mineralization belt on the south margin of Songji uplift in the southwestern North China Platform. The area presents typical dual structure of platform basement and cap rock, of which the basement is formed by the Paleoproterozoic Songshan rock group, and the cap rock, a standard platform-type deposition, is composed of a set of Paleozoic marine clastic rock-carbonate rock formation, marine-continental aluminiferous coal formation and continental clastic rock formation. Through analysis on the ore-controlling factors and prospecting indicators of bauxite in the study area, the prospecting model is established and the resources potential is evaluated as well.
