slope fan

SA is mainly consisted of slope and basin fan sedimentary system.

SA主要由三角洲-滑塌浊积岩所构成，而SB主要为斜坡扇-盆底扇沉积体系。

The inner basin type slope break belt controlled the off shore sub-lacustrine fan system in the basin-level falling stage.

在基准面下降阶段，盆内坡折控制着远岸湖底扇的形成和分布。

The sedimentary facies types of the abrupt slope model include alluvial fan, fan delta, and so on. Moreover, the facies changed rapidly and the sorting of the rock is bad.

沉积相类型主要发育冲积扇、扇三角洲等沉积体系，并且相带变化快、岩石粒度分选差。

Sedimentary feature and significance of oil gas exploration of the slope fan system of the low system tract

低水位斜坡扇的特征及在油气勘探中的意义

Since Xia and Shang dynasties, the human agricultural cultivation activities affected the surface of pluvial-alluvial fan and promoted the slope runoff erosion and deposit process.

自夏商时代以来，农业耕垦活动影响古洪积扇地表，促进了坡面流水侵蚀堆积过程，发生了面状流水侵蚀；

In front of the middle segment of the mountain, there is Dashuigou alluvial fan with coarse sediment, moderate slope and less fan area.

中段的大水沟等四个扇体组成物质较粗，坡度较大，而面积较小。

Each sequence can be subdivided into lowstand, transgression and high-stand depositional system tracts which consist of basin-floor fan, slope fan, slump fan, condensed section and various progradational wedges.

每一层序还可细分出低水期、水进期、高水期沉积体系域以及组成它们的盆底扇、斜坡扇、滑塌扇，缓慢堆积段和各种类型楔状体沉积。

The simulation and sedimentary dynamic analysis of fan delta in the steep slope of fault basin

断陷盆地陡坡带扇三角洲模拟及沉积动力学分析

The sedimentary systems of lowstand system tracts include basin floor fan, slope fan, progradational wedge, delta, fan delta, alluvial fan, submarine valley and incised valley.

构成低位体系域的沉积体系主要有盆底扇、斜坡扇、前积楔、三角洲、扇三角洲、冲积扇、海底峡谷和下切谷等。

3-D modeling of sedimentary facies of steep-slope fan reservoir

地面坡度陡；陡坡扇储集层三维沉积相建模研究

During the sedimentation period of Shawan Formation, there developed four types of sedimentary facies as gentle slope fan delta, shallow braided river delta, alluvial fan, coastal shallow-lake.

沙湾组沉积时期主要发育了缓坡型扇三角洲、浅水辫状河三角洲、冲积扇、滨浅湖滩坝等4种沉积相类型。

The model shows that current of alluvial fan progressed in the direction of SEE along the short axle with steep slope, and its current energy can keep only in short distance.

该模式表明，对于水流能量保持能力差的冲积扇，其古流向应该沿短轴陡坡降方向，即大致为SEE方向；

Western gentle slope is mainly developing fan delta and eastern steep slope developing underwater fan. 3 、 The reservoir is mainly the front of fan delta, submarine fan sand.

西部缓坡带以扇三角洲为主，东部陡坡带发育有水下扇。

Depositional mode and seismic recognition of sandstone and conglomerate fan bodies in the abrupt slope zone of terrestrial facies lake basin

陆相湖盆陡坡带砂砾岩扇体的沉积模式及地震识别

This paper suggests that the lowstand wedge and the slope fan near the continental-shelf slope break should serve as the petroleum exploration target of the hidden traps worthy of attention.

指出了陆架坡折附近的低水位楔和斜坡扇是值得注意的隐蔽圈闭勘探目标。
