摘　　要：安徽怀宁查家山铁矿床位于长江中下游成矿带安庆矿集区内,为一典型的矽卡岩型铁矿床。查家山铁矿床主要赋存于下二叠统栖霞组与闪长岩接触带上,其赋矿层位不同于安庆矿集区已知的矽卡岩型矿床赋矿层位,查家山铁矿的发现拓展了区域找矿方向。本文系统总结了查家山铁矿床的地质特征,分析了区域找矿潜力,为安庆矿集区下一步寻找矽卡岩型铁矿工作提供依据。The Chajiashan iron deposit is a typical skarn one located in the Anqing cluster of ore deposits in the middle and lower reaches of the Yangtze River metallogenic belt.The ore bodies mainly occur in the contact zone between diorite and the Qixia Formation of the Lower Permian,and the ore-bearing horizon is different from those of the known skarn ore deposits in the cluster,which indicates a new ore-prospecting direction in the region.This paper systematically summarizes the geological features of the Chajiashan iron deposit,analyzes the regional prospecting potential,and provides a basis for further searching for skarn iron deposits in the cluster.
