| Outline of Final Research Achievements |
Surface heat flow provides important constraint to improve our understanding of the thermal evolution and structure of the Earth. However, the number of heat flow data is limited and spatially very inhomogeneous. To provide an attempt at a higher resolution map of heat flow, heat flow and thermal conductivities are measured and compiled. The planned database will serve as a home to data relevant to thermal studies.
Meanwhile, there exist many indicators that are proxies for quantifying the thermal structure. One of the promising indicators is the centroid of magnetic layer, Zo, based on spectrum analysis of magnetic anomaly data. Global distribution of Zo is closely related to reasonable average thermal regime and its correspondence with tectonic regime indicates that Zo is useful to delineate regional crustal thermal structure. It is expected that Zo combined with multidisciplinary data should help to infer geophysical and geological information in less explored regions.
