It is thought that the channel bay line evolution processes can be divided into four stages. The first stage is soon of the sea level stable when the bayhead mountines are eroded and developed abrasion geomorphy and the productive materials were transport into the bay deposition by the tidal current and wave current and were reworked into gravel dams. The second stage is characterized by the fluvial output sediments and eroded sediments mixed deposition in channel bay and developed marine accumulation plain and sand riges in the plain under the wave reworked. The third stage developed clay silt marine accumulation plain under the action of the channel current and the wave action is very limited. The fourth stage is marked by human being reclaim which result in the channel bay filled and evoluted into a strait arce coast.

文章认为，峡道海湾的充填经历了四个阶段，第一阶段以峡道海湾湾顶山体在波浪作用下产生的侵蚀物质充填为主，发育了海蚀崖、海蚀洞、海蚀穴等侵蚀地形和湾顶砂砾石堤等堆积地形交替的峡道湾顶地貌，第二阶段以河流输出物质和峡道湾岛屿、礁石侵蚀物质在潮流作用下向峡道湾输运，由潮流和波流共同沉积为特征，发育海积平原，部分粗颗粒泥沙在波浪的改造峡，发育平原沙堤，第三阶段以河流输出物质为主，在涨落潮流搬运下进入峡道和峡道湾沉积，在峡道湾中发育以淤泥质粉砂为主要物质的海积平原，第四阶段以人类围涂造田为标志，加速峡道湾的充填过程，使峡道海湾最终趋于夷平，形成顺直均衡的弧形海岸。

Results demonstrate that climate fluctuations recorded by the two boreholes correspond to the marine oxygen isotope stages. Thick layer of coarser grained fluvial deposits and the third layer of "hard mud" were deposited in the study area during MIS 6, reflecting a cold climate. The sediments became fine-grained and indicate a coastal marsh depositional environment during MIS 5. The second layer of "hard mud" was deposited during MIS 4. Fine-grained coastal marsh deposits dominated in the study area during early MIS 3, while lagoon-beach ridges prevailed during middle and late MIS 3, forming a layer of silt and fine sand in the coastal plain. The MIS 2 strata are composed of a typical sedimentary sequence with coarse grain in the lower section and fine grain in the upper section, i. e. yellowish grey or brownish yellow silt and brownish yellow or dark green "hard mud", respectively.

研究结果显示，两孔记录的古气候波动可与深海氧同位素曲线进行对比：对应于深海氧同位素曲线第6阶段(MIS6)，堆积厚层的河道相粗颗粒沉积及第3硬土层，反映当时气候寒冷；第5阶段(MIS5)，为滨海湖沼沉积，沉积物的颗粒显著变细；第4阶段(MIS4)，本区形成第2硬土层；第3阶段(MIS3)的早期，本区也发育滨海湖沼沉积，中晚期则形成潟湖—砂坝体系，在滨海平原区普遍发育粉、细砂层；第2阶段(MIS2)，地层由下粗上细的沉积序列构成，下部为黄灰、棕黄色粉砂，上部则为棕黄色或暗绿色硬粘土。

榆树林油田处于松辽盆地北部中央坳陷区三肇凹陷东部斜坡，主要产油层系是中生界白垩系泉三、四段的扶余、杨大城子油层，储层为河流相沉积，主要砂体为有底钙存在的正旋回河道砂体，微电极曲线形态为箱型；其次为姚一段的葡萄花油层，储层为三角洲内前缘沉积，主要砂体为水下分流河道砂体，微电极曲线形态为箱型。

The basin is one of the Cenozoic rift basins, which has experienced a series of paleo-climate change since Early Pleistocene, including wet cold, wet-warm, and arid. A former lake was believed to develop at the early stage of late Pleistocene (around 120 ka BP), and vanish during the Holocene. With the vanishment of the lake, the early Yellow River occurred. It results in a complex sedimentary environment with fluvial and lacustrine sediments interlacing each other.
