| 摘 要： | 本文详细研究了伊通盆地莫里青断陷双阳组沉积类型，并将该区湖泊水下扇的岩相组成划分为5种类型：经典浊积岩相、块状砂岩相、砾质砂岩相、颗粒支撑砾岩相、基质支撑砾岩相；将湖泊水下扇划分为内扇、中扇、外扇三个亚相，对各亚相进一步划分了若干微相。湖泊水下扇沉积为该区地层的主要沉积特征，在垂向上具有进积型和退积型两种类型。 |
| 关 键 词： | 伊通盆地 莫里青断陷 双阳组 水下扇 沉积物重力流 |

| Abstract: | This paper reports the detailed study of the sedimentary facies types of Shuangyang Formation in Moliqing faulted depression of the Yitong Basin. There are five lithofacies contributing to the formation of submarine fan:matrix cement conglomerate,grain supported conglomerate,conglomerate-sandstone,massive sandstone,and classic turbidite. The submarine fan is divided into inner,middle and outer fans,each of which can be subdivided into many microfacies. Submarine fan is the main sedimentary features of Shuangyang Formation. The transgressive and regressive cycles are co-existed on the vertical section. |
| Keywords: | Yitong Basin Moliqing faulted depression Shuangyang Formation submarine fan sediment gravity flow |
