摘要: 20世纪80年代以来,一些学者提出了松辽盆地白垩纪有过海侵作用的新观点。海源生物、钙质超微化石、海绿石等指相化石及矿物的发现被认为是松辽盆地白垩纪海侵的主要证据。结合松辽盆地岩相古地理研究的最新成果,对松辽盆地海侵事件提出了质疑。全球海平面变化与湖侵高水位的不一致,盆地东部榆树水系的发现及地球化学等资料表明白垩纪时松辽古湖盆是封闭湖盆。海源生物、海绿石等的发现只能说明古湖盆水体的咸化作用,海侵论依然缺乏海侵的有效证据。

Abstract: Since the 1980s, some scholars put forward a new point of view that transgression had taken place in the Cretaceous in Songliao basin. Discovery of such facies fossils and minerals as sea creatures, calcareous nannofossils, glauconite, etc. is considered to be the main evidences of that transgression event. Combined with the latest research results of lithofacies palaeogeography in Songliao basin, the transgression event in Songliao basin is worth to question. All the evidences of inconsistence of global sea?level change with the high water level of lake transgression, the discovery of Yushu river system in eastern Songliao basin and geochemical data show Songliao basin was an enclosed lake basin in the Cretaceous. The discovery of sea creatures and glauconite, etc. just indicates the saline effect of water in this ancient lake basin, being still a lack of valid evidences of such a transgression event
