Abstract: In the Jingbohu volcano area of Heilongjiang province, MT measurement of 30 sites has been done. The results are as follows. The explored zone is non 1D structure. The central part is 2D structure. Its strike direction is north-east. In the vertical orientation there are three resistivity layers. Upside resistivity is middling value. Middle is high value. Bottom is low value. The surrounding resistivity of the explored area is larger. In the middle part of the explored area there is low resistivity (relative to periphery) vertical columniation of which the section is not regular, and its strike direction is north-east, and its resistivity has a “middle-high-low” style from the top to the bottom.

摘要： 在黑龙江镜泊湖火山地区做了30个点的大地电磁测深工作。结果表明:测区为非一维结构,中部为二维结构,走向为北东向。上下大致可分为3个电性层,电阻率上部为中阻,中部为高阻,下部为低阻。测区四周电阻率高,中部有一个截面不规则的北东向拉长的低阻立式柱状体,该柱体的电阻率从上到下也呈“中-高-低”形式。
