山东汶上张家毛坦铁矿地质特征及找矿方向

Geological characteristics and prospecting direction of iron ore of Shandong Wenshang Zhang Maotan

张家毛坦铁矿位于汶上-东平铁矿成矿带南东部。区内圈定铁矿体17个,矿体赋存于泰山岩群山草峪组中。总体走向315°~320°,倾向SW,倾角45°~60°,矿石工业类型为需选磁性铁矿石,成因类型为沉积变质型铁矿床。根据高精度磁测结果结合钻探揭露情况,矿床深部具有良好的找矿潜力。

Zhangjiamaotan Tie Iron Mine is located in the southwest of Wenshang-Dongping iron ore metaUogenic belt. There are 17 iron ore bodies in the area, and the orebody is found in the group of Taishan Gr. The ovreraU trend of 315 o 320 o , tend to SW, angle 45°-60° , the type of deposition of metamorphic iron deposits. According to the high- precision magnetic test results combined with the drilling to reveal the situation, the depth of the deposit has a good potential for prospecting.
