Description

Two new heat flow values were determined at Houfu in Yamaguchi Prefecture, and at Kunisaki in Oita Prefecture, Southwest Japan. These two heat flow stations are located in Palaeogene and Cretaceous granitic rock regions. We determined a relatively low heat flow value of 39.4±8.1 mW/m2 at Houfu and a relatively high value of 79.1±3.5 mW/m2 at Kunisaki. The latter value is anomalously high in comparison with the geologic are-heat flow dependency (Polyak and Smirnov, 1968), suggesting a possible deep magmatic activity in recent ages, although other explanations are possible. Quantitative analyses are necessary to clarify the origins of such high heat flow observed in the old granitic region.
