| 英文摘要 | There have been a number of studies on lithospheric thermal structure in continent, but few in oceanic or continent-ocean transition zones. Based on submarine heat flow data and related petrological thermal properties available in Qiongdongnan Basin, we calculate the constitution of heat flow and deep temperature of different layers along four distinct seismic profiles. The crustal structure in this area is divided into four layers based on latest analysis of P-wave velocity variation, that is sediments, upper crust, normal lower crust and anomalous lower crust with high velocity, respectively. The results demonstrate that mantle heat flow increases from shallow water to deep water, which is the predominant factor in the current distribution of submarine heat flow in Qiongdongnan Basin. Besides, its contribution to submarine heat flow is 76.3 +/- 7.0% on average, suggesting a typical feature of "Cold Crust and Hot mantle" lithospheric thermal structure. In addition, Moho temperature beneath the Qiongdongnan Basin is mostly in the 500 similar to 700 degrees C range with a lower temperature region and two higher temperature regions, which is primarily ascribed to the extent of the lithospheric thinning of the northern margin and well-developed faults of the South China Sea. |
