利用航磁异常圈定鲁西南地区岩浆岩

Delineation of Igneous Rocks in Southwestern Shandong by Using Aeromagnetic Anomalies

基于鲁西南地区航磁资料,分析了磁异常的成因,圈定了岩浆岩,并探讨了其分布规律及对该区煤层的影响.结果表明,研究区磁异常发育,断裂控制了岩浆岩的分布规律,岩浆使煤层的结构等更加复杂,对煤层煤质影响极大.研究结果对煤田的勘探和开发有着重要的指导意义.

On the basis of aeromagnetic data of southwestern Shandong. The causes of magnetic anomaly have been analyzed, igneous rocks have been delineated, and the regularities of distribution of igneous rocks and the impact on coal seam of the area have been discussed. The results showed that the magnetic anomaly developed in the study area, the faults controlled the distribution of magnetic rocks. Igneous rocks made the structure of coal seam more complex and had great influence on quality of coal seams. Therefore, the research results have great guiding significances to exploration and production of coal mine.
