摘要
山东省10年找矿突破战略行动开展以来,先后在鲁西莱芜和齐河-禹城深覆盖区取得了高品位矽卡岩型铁矿重大找矿突破。莱芜地区矿山岩体周边覆盖区发育有明显的航磁异常,通过对牛泉覆盖区磁异常和地质特征综合研究,认为该区具备良好的矽卡岩型铁矿成矿地质条件。并通过异常查证和系统的钻探施工,在牛泉覆盖区探明了一处中型矽卡岩型铁矿床。本文在总结勘查成果的基础上,分析了矿床主要成矿条件,探讨了找矿标志,对成矿有利部位进行了简单预测,以期为莱芜地区矽卡岩型铁矿下一步勘查工作提供帮助。
Since the implementation of the 10 year prospecting breakthrough strategic action in Shandong province,major prospecting breakthroughs of high grade skarn type iron deposit have been made in Laiwu and Qihe Yucheng deep coverage areas in western Shandong.There are obvious aeromagnetic anomalies in the coverage area around the mine rock mass in Laiwu area.Through comprehensive study on magnetic anomalies and geological characteristics in Niuquan coverage area,it is considered that this area has good geological conditions for skarn type iron mineralization.Through anomaly verification and systematic drilling,a mediumsized skarn iron deposit has been proved in Niuquan covered area.On the basis of summarizing the exploration results,main metallogenic conditions of the deposit has been studied,prospecting criteria has been discussed,and a simple prediction of the favorable parts of mineralization has been predicated.It will provide some references for the exploration of skarn type iron deposit in Laiwu area.
