It is the aim of these surveys to supplement an aeromagnetic survey conducted by Y. Kato and others as one of the targets of the project named \"\"Combined Aeromagnetic-Gravity Studies of Calderas in Japan\"\", U.S.-Japan Cooperative Science Program. A marked gravity low associated with magnetic highs was discovered in the central portion of the area. A depression of granitic basement of 1800m in depth is presumed there. The magnetic highs seem to be associated with andesite lavas forming the peaks which look like central cones. This data strongly suggests that the Onikobe area is a sort of caldera, this conclusion seeming to harmonize with the present geological view.", "subitem_description_type": "Abstract"},
