Geothermal play fairway analysis at a populated rifting basin area of Taiwan

摘要

Taiwan is located in the active mountain belts on the west side of the Pacific Rim with promising potentials for geothermal resources. The triangular shaped Yilan Plain, our study area chosen for a geothermal development pilot project, resides at the southwestern end of the Okinawa Trough behind the Ryukyu Arc-Trench where the Philippine Sea Plate is subducting beneath the Eurasian Plate with low-grade metamorphic rocks exposed in the surrounding mountain ranges.
