| Abstract | In this work, the results of a numerical study of the d~st~ibution of deep temperatures and of the heat flow at depth over an area of some 100,000 km In Central Honshu, Japan, are presented. Due to compl icated geological-structural characteristics of the crust and specific plate tectonic features of the I ithosphere, this area has extensively been investigated by different geophysical methods for decades. Of the quite abundant number of seismic-refraction profi les avai lable in the region, we have carried out temperature calculations along six transects with a total length of some 2000 km. The profi les were selected so as to consider possibly different geological environments and structural units and also to achieve a relatively uniform coverage of the area of interest. To complete information on crustal structure, the results of certain three-dimensional crustal models in the Kanto-Tokai District (lshida,1984; Ashiya et al.,1987) have also been used in a I imited amount. |
