| 摘 要： | 本文在综合分析海峡两岸有关资料的基础上,提出我国东南沿海在白垩纪早期曾受到海水的影响。根据PK—2井中的菊石属于地中海沿岸地理亚种这一事实,提出我国东部在白垩纪早期可能与特提斯海有某种联系。最后,通过有机地球化学指标,镜煤反射率的测定和该区下白垩统海相地层中含有丰富的生物,指出该地层有良好的生油、储油气的可能性。

| Abstract: | Based on the comprehensive analysis of the geological data about the east and west coasts of Taiwan Strait, this paper proposes that the southeast coastal areas ot our country were affected by sea water during the period of early Cretaceous. According to the fact that Holcophylloceras caucasicum found in PK-2 well belongs to the geographic subspecies of Mediterranean coastal areas, it is suggested that there could be certain connection between east China and Tethys Sea during early Cretaceous period. Finally, in accordance with organo-geochemical index, vitrain reflectivity, and abundant organism in the marine stratum of lower Cretaceous, it is indicated that there could be good prospects of oil and gas in the stratum. |
