英文摘要
Thermal effects of subducted ridges and their roles in continental growth have been investigated, based on seismology, sedimentology, petrology-structural geology, and numerical simulation for the triple junction and the surrounding area in Chile and SW Japan. Natural earthquakes, subsidence and sedimentary environment in the forearc region, igneous activity and deformation history, and thermal-melting structure beneath the region have been constrained, indicating that a large amount of granitic melt can be produced associated with ridge subduction.
