英文摘要The bidirectional subduction system, island arc magmatic activities, and thermal structure of the forearc basin in the Molucca Sea are taken into consideration in this study. The active volcanic arcs on both sides of the bidirectional subduction zone in the Molucca Sea are undergoing arc-arc collisions. We applied a finite element thermal simulation method to reconstruct the thermal evolution history of the Molucca Sea Plate based on geophysical data. Then, we analyzed the thermodynamic characteristics of island arc volcanism on both sides of the bidirectional subduction zone. The results showed that at 10 Myr, the oceanic ridge of the Molucca Sea Plate was asymmetrically biased to the west, causing this bidirectional subduction to be deeper in the west than in the east. Furthermore, the oceanic ridge subducted under the Sangihe arc at 5.5 Myr, causing intermittent cessation of volcanic activities. Due to the convergence of bidirectional subduction, the geothermal gradient in the top 3 km depth of the forearc area between the Sangihe and Halmahera arcs decreased from about 60degree celsius km(-1) at 4 Myr to about 38 degree celsius km(-1) today. Finally, within the 45-100 km depth range of the sliding surface of the subduction, anomalously high-temperature zones formed due to shear friction during the bidirectional subduction.
