| 摘 要： | 对松辽盆地东南隆起区嫩江组剖面进行厘米级刻画,分析其为一套深湖相与滨浅湖交互相沉积。在滨浅湖交互相沉积段,水体频繁波动,且波动幅度大。根据颜色、岩性将嫩江组一段地层划分为34个米级旋回,Fischer图解分析将米级旋回归并为11个五级旋回和2个四级旋回。剖面中发育的介形虫灰岩、白云岩结核和火山灰层在松科1井嫩江组一段连续取心中都有响应;剖面和井的Fischer图解对比发现,第15个旋回开始到第25个旋回结束,松辽盆地沉积中心向西北方向迁移,且可能伴随着盆地东缘的抬升运动。

| Abstract: | Described (centimeter scale) the field section of Cretaceous Nenjiang Formation (K2n) in southeast uplift zone of Songliao Basin. There are three sedimentary subfacies including deep lake, shallow lake and coastal lake subfacies. The water level fluctuated frequently with large fluctuation amplitude. The first member of Nenjiang Formation was composed of 34 meter-scale cycles, 11 fifth-order cycles and 2 fourth-order cycles in the field section. Ostracoda limestone layer, dolomite concretion and volcanic ash layer which developed in the field section were also found in the core section of CCSD-SK-I. Comparing the Fischer plots between the field section and the core section, from the fifteenth cycle to twenty-fifth cycle, the depocenter of Songliao Basin moved from southeast to northwest corresponding to the uplift of eastern basin. |
