红土山盆地为大面积玄武岩覆盖区，其地球物理特征表现为中、强磁性、高密度。常规重、磁、电等地球物理方法很难取得较好的效果，故开展新方法、新技术以填补长白山玄武岩覆盖区及周边找矿空白，通过电磁勘探可获得研究区内地层电性结构，推断出新生代军舰山组玄武岩，中生代上统石人组和下统义和组沉积岩厚度变化规律、产状特征，及基岩起伏和构造分布情况，为该区成煤靶区的寻找提供了新的物探资料。

Hongtushan Basin is almost covered by basalt, with geophysical features of moderate and strong magnetism, high density. Normal gravity, magnetic, electric and other geophysical methods are dififcult to gain good results, therefore using new method and technique can remedy the exploration deifciency of basaltic coverage in Changbai Mountain and its surround area. Trough the electromagnetic exploration, we can get stratum electrical structure within this basin , can estimate the thickness variation trend, occurrence features of Junjianshan Formation basalt in Cainozoic, sedimentary strata of the Upper Shiren Formation and the Lower Yihe Formation in Mesozoic, and basement rolling and structural distribution. In addition, new geophysical prospecting data is provided for coal exploration in target areas.
