自晚侏罗世火山喷发渐趋宁静之后,在浙闽隆起带上形成了数以百计的小型盆地。它们是多期构造运动遗留的痕迹。

The numerous basins of small and medium size in Zhejiang Province can be grouped according to their tectonic origin into four types,i.e.,Shou-chang,Yongkang,Jinqu and Tiantai.Basins of the same type were formed in the same period with similar structural features and evolutional history.Classification of the basin types provides informations of the structures which may serve as the basis for analogizing basins and estimating oil and gas resources.Classification of basins can be carried out according to their basinal outlines and structural trends.Therefore,overlapped basins or the deeper strata of basins can be predicted.Through studies on the structures of basins,paleo-stress field in the Zhemin uplift zone and the structural history cf the uplift can be reconstructed.This would be helpful in the search of the basement structures of the Yellow Sea and East China Sea and making assessment of oil and gas resources in this attractive area.
