摘要
本文通过野外地质调查和综合分析对比前人资料的基础上,对和龙盆地的岩石地层序列进行了详细总结,在系统查证和综合分析的基础上将和龙盆地演化分为三个演化旋回,确定和龙盆地为晚侏罗世断陷盆地、早白垩世断坳转化盆地和晚白垩世坳陷盆地叠加的复合盆地。
This paper summarized lithostratigraphy sequence of Helong basin by means of comprehensive and comparative analysis of the field geological investigation and previous data. Basin evolution of Helong basin can be divided into three cycles of evolution on the base of systematic verification and comprehensive analysis. Helong basin is considered as a composite basin superimposed by Later Jurassic fault basin, Early Cretaceous fault-depressed basin and Late Cretaceous down-warped basin.
