鲁西南单县地区赋存沉积变质型铁矿，近年来，该地区铁矿找矿取得了较大的进展。为了更好地指导区内铁矿勘查工作，通过介绍单县地区铁矿地质特征、地球物理特征，剖析大刘庄铁矿床、龙王庙铁矿的矿床特征，建立找矿标志，并对今后铁矿找矿方向进行研究。单县大刘庄、龙王庙铁矿赋存于新太古代泰山岩群山草峪组中；铁矿体总体呈层状、似层状，局部呈透镜状，铁矿体产状与围岩一致。通过分析认为，区内的铁矿总体受山草峪组控制，构造、侵入岩对铁矿有破坏作用。经过对重磁测量成果分析，总体认为磁异常及其化极明显部位是区内铁矿勘查中最重要的指示标志，重力梯度带是铁矿赋存的重点位置。通过对以往勘查成果的综合分析认为，辛羊庙异常区应为今后铁矿勘查工作的首选地区。

Sedimentary metamorphic iron deposits are widely distributed in Shanxian county in southwest of Shan -dong province , and great progress on exploration has been made in the area of iron ore in recent years .In order to better guide the iron ore exploration in Shanxian county , geological and geophysical characteristics of iron deposits have been introduced in this paper .With comparison of iron deposit characteristics of Daliuzhuang and southwest Longwangmiao , prospecting criteria has been established and the exploration directions in the future has been stud-ied.Daliuzhuang and Longwangmiao iron ore deposits occurred in the Shancaoyu formation of Archaean Taishan group.Ore bodies are layered and stratoid type , while are lenticular type in regional areas .Its occurrence is con-sistent with its surrounding rock .Through analysis on iron deposits in Shanxian county , it is regarded that iron ore bodies are controlled by Shancaoyu formation , and structures and intrusive rocks can damage iron deposits . Through analysis on gravity and magnetic survey , it is considered that the distinctive positions of magnetic anomaly and obvious polarization are the most important prospecting indicators , while gravity gradient zones are key positions of iron deposit .With comprehensive analysis of the previous exploration results , it is regarded that Xinyangmiao a-nomaly area is the first choice for iron prospecting in the future .
