Abstract
Detailed heat flow measurements were carried out around the ODP contingency drilling site KS-1(2448'N,12230'E) located on the southern slope of the southwestern end of the Okinawa Trough. A total of 26 heat flow values were obtained. Within about 10 km of the site, the heat flow is lower than 50 mW!m2 Heat flow increases southward to about 65 mW/m2 on the south edge of the trough. Due to the extraordinarily high sedimenta tion rates, the sedimentation-corrected heat flow values have increased by as much as 76 % , so only the most recent surface sedimentation effects are considered. Distribution of heat flow patterns shows that high heat flow values are associated with igneous activities and are observed in both the northern and southern flank and the western end of the Okinawa Trough.
