摘要: 对我国东部下第三系源岩发育的壳幔背景及空间展布、源岩发育的构造背景、沉积和盆地环境、有机质赋存状态、有机质丰度、类型及地温场特征等方面的研究表明,秦岭-大别和郯庐断裂的生成演化是区内下第三系盆地发育的主要构造控制因素,渤海湾北东向裂谷型盆地规模大、切割深,有效烃源岩最为发育;南华北近东西向-北西西向断陷型盆地规模小、切割浅,有效烃源岩相对最不发育;而立交桥型的南襄盆地有效烃源岩发育程度介于两者之间。

关键词: 中国东部, 下第三系, 有效烃源岩, 构造演化, 有机质丰度, 沉积环境, 地温场

Abstract: The crust-mantle background and space distribution of palaeogene source rock in the east of China,the tectonic background,sediment and basin environment,state of organic matter,abundance of organic matter and type of organic matter in source rocks and geothermal field characters are analyzed.The generation and evolvement of the Qinling-Dabie Orogen and Tanlu Faults are the primary factors for controlling the tectonic development of the Palaeogene basins.The effective source rock is enriched in the north-east rift basin of Bohai Bay because of its large scale and deep cut.The effective source rock in the southern North China near EW-NWW trend faulted basin is the poorest because of its small scale and shallow cut.The developing degree of the effective source rock in Nanxiang Basin with cloverleaf junction lies in medium of the above basins.

Key words: east of China, Palaeogene, effective source rock, tectonic evolvement, organic matter abundance, sedimentary environment, geothermal field
