摘要: 中国东北地区内陆盆地下白垩统充填火山岩、火山碎屑岩和含煤碎屑岩沉积组合,上白垩统充填以砂、泥碎屑岩为主的河流相、湖泊相沉积组合。盆地沉积演化史和生物发育史研究表明,地质群发事件阶段性特征明显,早白垩世的火山事件,中白垩世的超静磁带和极端温室气候及古湖泊缺氧事件与全球同期重大地质事件的发生具有较好的协同性。同时,盆地内湖生生物群演化表征为热河生物群、松花江生物群和明水生物群的顺序出现、突发演化和显著的种群绝灭现象,显示出生物与环境变化的一致性。

Abstract: Sedimentary combinations of volcanic rocks, volcaniclastic rocks and coaly clastic rocks distributed in Lower Cretaceous in the continental basin in northeast China, and Upper Cretaceous is featured with the depositional combinations of fluvial facies and lacustrine facies mainly as sandstone and mudstone clastic rocks. Research on basin sedimentary evolution history and biological development history indicates that geologic group events have obvious stages. Volcanic events in Early Cretaceous, Cretaceous normal superchron, extreme greenhouse climate and paleo-lake anoxia events in Middle Cretaceous are well identical with important global geologic events at the same period. At the same time, lacustrine biotic evolution inside the basin is featured by ordered appearance, breaking evolutions and significant population extinction phenomena of Jehol biota, Songhuajiang River biota and Mingshui biota, showing consistency between biota and environment changes.

Key words: biota, geologic events, biotic response, Late Mesozoic, northeastern China
