DEEP ELECTRICAL STRUCTURE OF THE WUDALIANCHI VOLCANIC CLUSTER IN HEILONGJIANG PROVINCE, CHINA

摘要

To study the magma chamber and deep structure in Wudalianchi, Heilongjiang Province, the magnetotelluric measurements were carried out at 71 sites along three EW profiles and four NS profiles in the Wudalianchi volcanic cluster and the vicinity. It is shown by preliminary results that there is a high resistive body with rivet shape beneath the cluster at the depth from a few hundreds meters to about 15-20 km. It is postulated that the high resistivity body is a cooled magma chamber and it passes through
