Besides, the sedimentary facies of upper ganchaigou and lower ganchaigou formation were also mapped in supersequences which are the main target strata for exploration. the high resolution sequence stratigraphic framework showed the genetic relationship between the distributions of sedimentary facies and their tectonic settings. the near - source sedimentary systems such as subaqueous alluvial fan and lake - floor fan are often deposed in rise - hemicycles in the steep slope background in the north, the coarse lithology of fan - delta prograded from north to south in fall - hemicycles, and the braided stream facies are formed in the rise - hemicycles in gentle slope background in the south, braided stream facies prograded from sorth to north in the fall - hemicycles, but the lacustrine facies and salt lake facies developed in the middle part of the area
詳細的沉積相研究發現,紅獅地區第三系發育有沖積扇、水下沖積扇、河流、三角洲、扇三角洲、湖泊和湖底扇7種主要沉積相類型,並對作為區內主要勘探目的層系的下乾柴溝組和上乾柴溝組進行了以超層序為單位的沉積相平面編圖,以較高的時間解析度揭示了區內沉積相帶的平面展布及其在不同構造背景中的分佈規律,比如在北部的凹陷陡坡背景下,上升半旋迴低水位期通常發育有水下扇、湖底扇等陡岸近源特徵的沉積體系,下降半旋迴高水位期,扇三角洲相粗碎屑巖由北向南進積;在南部的凹陷緩坡背景下,上升半旋迴主要發育辮狀河流相,下降半旋迴辮狀河三角洲相由南向北進積;而中部紅柳泉一獅子溝一帶則為湖泊相沉積和鹽類沉積。There are 5 depositional systems in the region. they are panne and jishan delta systems coming from chengning heave near the northwest border of the region, shuangfeng delta located in southwest part of the region coming from luxi dome, qudi fan - delta located in the southeast of the studying area and the sub - fan near fault or fan - delta of the southern part of the region. based on the study of sedimentary facies and depositional systems, 11 lithological traps are predicted
在等時地層格架內對沙三段各中期基準面旋迴內的沉積相和沉積體系進行了詳細研究,確定了沙三段沉積時期發育的五種沉積體系類型,即來自凹陷西北邊界埕寧凸起的盤河三角洲體系和基山三角洲體系、來自魯西隆起、分佈在凹陷西南部的雙豐三角洲體系、東南部的曲堤(扇)三角洲體系,南部的近岸水下扇/扇三角洲體系。They clung to the purple moors behind and around their dwelling - to the hollow vale into which the pebbly bridle - path leading from their gate descended, and which wound between fern - banks first, and then amongst a few of the wildest little pasture - fields that ever bordered a wilderness of heath, or gave sustenance to a flock of grey moorland sheep, with their little mossy - faced lambs : - they clung to this scene, i say, with a perfect enthusiasm of attachment
她們眷戀住宅後面和周圍紫色的荒原一眷戀凹陷的溪谷。一條鵝卵石築成的馬道,從大門口由高而低通向那裡,先在蔽樹叢生的兩岸之間蜿蜒著,隨后又經過與歐石南荒原交界的幾個最荒蕪的小牧場。一群灰色的荒原羊和苔蘚般面孔的羊羔,都靠這些牧場來維持生命嗨,她們熱情滿懷地眷戀著這番景色。Under the all different structures " combination, the water surface had large bias and turn - around in the torturous path, and in the middle of the path along the longitude, there had the regularity that sink bank surface was higher than the convex bank one
在所有結構組合條件下,彎道水面都有較大偏斜和扭曲,並且在彎道中部主法線方向上,基本為凹岸水面高凸岸水面低的規律。But there had phenomena that the middle surface was higher than the both sides " and even the sink bank one was lower than the convex bank one
但彎道中也出現了中心線水面高兩岸低的情況,甚至還有凹岸水太原理工大學工程碩士學位論文2面低而凸岸水面高的情況。Founding that the fr of the tortuous path flow had all changed in longitudinal ( along the circuit ), transverse ( between the sink and convex bank ) and vertical orientation ( from the water surface to the bottom )
結果發現,彎道水流f _ r數在縱向(沿流程) ,橫向(凹凸岸間)和垂向(水面到底板)都是變化的。分享友人
