Research Abstract

In order to understand a petrological background for the natural diamond from Japan I carried out a petrological study of the mantle and cructal xenoliths in the Shingu alkaline basaltic dike The results suggest the following magmatic events :(1) high degree of partial meling of mantle and production of a large amount of magma, and subsequent melt transport though veins ;(2) mantle metasomatism probably by iron-rich melt ;(3) formation of gabbro-norite through interaction between mantle and undersaturated alkaline magmas that have caused at depths. These magmatic activities have significant contributions to the thermal and lithological structures just before the subduction of Philippine Sea plate. Although there is no petrological signature found in the xenoliths for diamond-stable high-pressure conditions, the host alkali basaltic magma with significant amount of CO2 might be such a high pressure origin.
