| 摘 要： | 在山东省齐河—禹城一带,选择航磁异常与区域重力异常套合地区,实施了大比例尺重磁测量,经钻探验证在该区首次发现了总厚度72.73m、全铁平均品位56.75%的厚大富磁铁矿,取得了地质找矿的重大新发现。矿体产于燕山晚期中-基性岩浆岩与奥陶纪马家沟群灰岩的接触带上,矿床成因为矽卡岩(接触交代)型磁铁矿床。该铁矿的发现是山东省近年来地质找矿的重大发现之一,预示在齐河—禹城地区进一步开展富铁矿找矿工作具有十分广阔的前景。

| Abstract: | The large-scale gravity and magnetic survey was carried out in the area delineated jointly by magnetic anomaly and gravity anomaly in Qihe-Yucheng area of Shandong Province. The rich iron ore deposit with a total thickness of 72.73m and a total iron grade of 56.75% were found for the first time and verified by drilling, which achieved a significant new discovery in geological pros-pecting. The orebodies which belong to skarn type magnetite were formed in the contact zones between late Yanshanian intermed-ite-basic magmatic rock and Ordovician limestone. The discovery of the iron ore deposit is one of the most important geological dis-coveries in recent years in Shandong Province, which opens up a very broad prospect for further development of rich iron ore explo-ration in Qihe-Yucheng area. |
