Abstract
Typical seismic sections of Lishui Sag were selected and analyzed using the balanced cross-section technique to calculate the rates of extension and compression that were applied to the sag in different tectonic evolutionary stages during the Cenozoic. The results show that Lishui Sag was in an overal extensional state during the Cenozoic. In terms of temporal evolution, the Paleocene Yueguifeng and Lingfeng formations were formed during a period of rapid extension, and the rates of extension and compression that were applied to the Lingfeng Formation were higher than those that were applied to the Yueguifeng Formation. Low rates of extension and compression were applied to the Paleocene Mingyuefeng Formation and to the Eocene Oujiang and Wenzhou formations. Besides these temporal variations, the rates of extension and compression varied spatially during each evolutionary stage. As well as quantifying the characteristics of the regional stress ifeld, the paper also analyzes the tectonic evolution of Lishui Sag. The temporal and spatial variations in the rates of extension and compression and the tectonic evolution of Lishui Sag represent the local response to the formation and development of the East China Sea shelf basin.关键词
