鸡西盆地鸡西群沉积层序及环境演化

将鸡西盆地发育期的整个地层垂向沉积序列,由老至新划分为10套沉积组合。通过对盆地10个沉积层序研究,阐述了鸡西群沉积初期、中期、末期的沉积环境,即由陆相—海陆交互相—陆相的沉积环境演化过程。

Jixi Group Sedimentary Sequences and Environment Evolution in Jixi Basin

The vertical sedimentary successions of Jixi basin are defined as ten sedimentary associations from the old to the new.Through researching 10 sedimentary sequences,Jixi basin's sedimentary environment of initial,middle and end period are expounded,that is the sedimentary environment evolution process from terrestrial facies land and sea facies-terrestrial facies.
