中文拼音 [chāoshānqū]
超扇區
英文
supersector-
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。This result lays a solid foundation for the research. 2. based on the study of petrology facies, facies association and sedimentary sequences, the sedimentary processes and systems are established. they consist of debris and hyper concentration flow deposits, channel deposit of braided and meandering streams, and alluvial fans, floodplains, fan - deltas and lacustrine turbidities
根據巖相、相組合以及沉積層序的研究，確立了研究區的沉積作用類型和沉積體系，它們包括碎屑流和超濃縮洪流沉積、辮狀河河道沉積，以及沖積扇沉積、洪泛平原沉積、扇三角洲沉積和湖相濁流沉積。
