| 英文摘要 | The Sea of Japan back-arc system almost retains the complete continent-ocean back-arc system, which provides an exceptional opportunity to study a virtually intact continent-ocean back-arc system. In this paper, tectono-thermal modeling is performed along five OBS (ocean bottom seismographs) profiles of the sea of Japan to reveal the spatial and temporal differences of the extension intensity and thermal evolution in different areas of the basin. The modeling results show that the total stretching factors during the back-arc spreading of the sea of Japan range from 1. 71 similar to 3. 59, with the larger value in the Japan basin in the north of the sea of Japan and the smaller value in the Yamato Basin in the southeast of the sea of Japan. The basin basement heat flow has only one peak and the peak period is different. The southeast of the basin reaches the peak value of heat flow (101 similar to 118 mW . m(-2)) during similar to 18. 2 similar to 17. 6 Ma, while the north of the basin reaches the peak value of heat flow (123 similar to 137 mW . m(-2)) during similar to 13. 8 similar to 12. 5 Ma. We infer that the back-arc spreading of the sea of Japan may be due to the dehydration of subducted slab, resulting in a wet and hot state of the overlying lithosphere, which makes its strength significantly weaker than the surrounding lithosphere, and then promotes the beginning of back-arc spreading. The interaction between the Pacific plate and the Philippine Sea plate may be the dynamic mechanism that caused the difference in the evolution of the Sea of Japan since the late Oligocene. |
