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.
