(1) On the basis of our new gravity data together with the gravity database of Gravity Research Group of Southwest Japan, "Gravity Anomaly Atlas of the Japanese Islands : South-West and Central Japan" (editors : Yamamoto, A. and Shichi, R.) was published in November 2004.(2) A new gravity anomaly map was drawn from a total of 1328 new gravity measurements in Nagoya City and its environs. The gravity anomaly data combined with bore-hole and surface geology data show that the vertical displacement of pre-Tertiary basements of the Biwajima-Atsuta Fault and the Atsuta-Nisshin Fault is approximately 550m and 350m, respectively.(3) Judging from a dense gravity survey, geological investigation and lineament analysis of the Miya basin area in northern Gifu Prefecture, the Miya basin was formed as a pull-apart basin by right-lateral movements of the Miya-toge and Enako Faults running parallel in NE-SW trend.(4) A detailed fracture mapping and geochemical analysis of granitic rocks in the Atera fault zone reveal that the influence of fracturing of the Atera Fault on the granitic rocks is prominent within 250m from the main fault plane.

(1)在我们新的重力数据的基础上，结合日本西南重力研究组的重力数据库，《日本岛屿：日本西南部和中部的重力异常图集》(编辑：Yamamoto，A.和Shichi，R.)(2)在名古屋市及周边地区共进行了1328次重力测量，绘制了新的重力异常图。重力异常资料结合钻孔和地面地质资料表明，碧瓦岛-阿苏塔断裂和阿苏塔-日申断裂前第三系基底的垂直位移分别约为550m和350m。(3)从岐阜州北部米雅盆地地区密集的重力调查、地质调查和线形分析来看，米亚盆地是由北东-南西走向平行的米亚托格断裂和埃纳科断裂的右旋运动形成的拉分盆地。(4)对阿特拉断裂带花岗岩进行了详细的断裂填图和地球化学分析，结果表明，阿特拉断裂的破裂作用对主断层面250m以内的花岗岩类岩石的影响最为显著。
