摘要
多道反射地震、地磁、钻井资料表明,东海存在中生代地层。区域地层、古生物、古地理环境分析表明,东海陆架盆地南部赋存发育海相中生界的可能性。中生代期间,包括台西南、粤东、闽西在内的中国东南沿海一带存在一海相沉积环境,它可能是西太平洋、也可能是从南海东部或中部经过的中特提斯洋伸向陆地的一个支角。该支角北部可能抵达东海陆架盆地南部。
Multichannel seismic reflection, magnetism and drilling data show that there are Mesozoic strata in the East China Sea (ECS) shelf basin. Comprehensive analyses of regional strata, palaeontology and palaeoenvironment indicate that Mesozoic marine facies strata may have developed in the southern part of the ECS shelf basin. A marine depositional environment might exist in the southeastern coastal area of China during Mesozoic, including the sea area to the southwest of Taiwan, eastern Guangdong Province, and western Fujian Province. This coastal area might be a gulf extending into land from the western Pacific Ocean or from Tethys passing across eastern or central parts of the South China Sea. It could extend northward as far as the southern part of the ECS shelf basin.
