外文摘要：The Cathaysian Block has undergone complex tectonic transformation since the Mesozoic, with significant topographic and geomorphological changes due to large-scale magmatism, as well as tectonism in the central area. Apatite fission track (AFT) and zircon (U-Th)/He (ZHe) data were used to reveal the tectonic-thermal evolution history of the southeastern margin of the Cathaysian Block in the coastal region during the Late Cretaceous in this paper. Results suggest AFT ages range between 36.3 +/- 2.7 Ma and 63.5 +/- 6.7 Ma with mean confined track lengths from 12.99 +/- 1.54 mu m to 13.7 +/- 1.54 mu m. ZHe ages are ranged from 72.6 +/- 4.5 to 113.3 +/- 7.0 Ma and concentrated in 90-100 Ma. Thermal history modeling indicated a multi-stage cooling history: (1) Widespread Late Cretaceous to Paleocene cooling across the entire coastal mountain. The Late Cretaceous cooling was coincident with rollback of the subducted paleo-Pacific Plate, which resulted in a negative inversion from compression to extension. (2A) rapid cooling beginning at similar to 60 Ma and at similar to 45 Ma, which was interpreted as temporally coinciding with continental rifting along the Cathaysian coastal margin, considered to have signaled the opening of the South China Sea (SCS); and (2B) a subsequent slow cooling stage with a small temperature change at similar to 50 degrees C-65 degrees C during the Oligocene to middle Miocene, accompanied by migration of the central rift to the marine basin. (3) A final stage of rapid cooling to surface temperature commencing about 18 and 10 Ma since the Miocene in response to multiple-plates interaction caused by the Tibetan Plateau uplift and the collision of the Philippine Block with the Eurasian continent.
