中国白垩纪和早第三纪孢粉植物群和有机岩的分布

本文简要地记述了我国白垩纪至早第三纪的孢粉植物群特征和它们所反映的气候条件,以及沟鞭藻类和疑源类在我国的已知地理分布。根据有机岩的形成受控于气候条件、沟鞭藻类和疑源类可能是油源生物的观点,认为贺兰山以东,秦岭、伏牛山一线以北地区;冈底斯山至南岭一线以南地区;东部沿海及新疆西部地区是我国白垩纪至早第三纪有机岩形成的最有利地域。     

CRETACEOUS AND PALAEOGENE PALYNOFLORAS AND DISTRIBUTION OF ORGANIC ROCKS IN CHINA

This paper illustrates the Cretaceous and Palaeogene palynofloras and climatic belts and deals with distribution of dinoflagellates and acritarchs. In view of the relationship between organic rocks and climatic environments and that between petroleum and phytoplanktons, the probably advantageous areas to the formation of organic rocks are drawn.
