| 摘 要： | 六盘山白垩纪盆地是六盘山内陆叠合盆地的一个单型盆地。形成了冲积扇—扇三角洲—滨浅湖泊、三角洲前缘—滨浅湖—中深湖、中深湖—浅湖沉积体系组合型式。充填序列划分为一个Ⅱ级及五个Ⅲ级构造层序,分别对应于初始裂陷、扩张裂陷—稳定坳陷、湖盆萎缩整体抬升3个演化阶段。

| Abstract: | Liupanshan Cretaceous basin is a mono - basin of Liupanshan inland overlapping basin. It formed such association types as alluvial fan - fan delta - shallow coastal lake, delta front - shallow coastal lake- semi - deep lake, semi- deep lake shallow lake sedimentary system. Filling sequences are divided one II class structural sequence, and five III class structural sequences, which belong to 3 evolution stages of initial depression, spreading depression stable depression, lake basin reducing accordingly. |
