Through the analysis of the stratigraphy and sedimentary facies of the research areas , the description model between the stratigraphic framework and deposite environment can be set up firstly by the transition from the " three horizons sandstone with two intercalated limestone horizons ' mn yanshiping area to shale and marl in amdo - zigetang co , and to oil shale in bilong co , then by the transition of the shallow water platform facies to the deep water continental shelf , slope , and to the deep water basin 通過對研究區(qū)地層和沉積相分析,建立起一個(gè)從北向南由雁石坪地層類型“三砂夾兩灰”過渡為安多?茲格塘錯(cuò)地層類型泥頁巖、泥灰?guī)r,最后到比洛錯(cuò)地層類型黑色油頁巖,由淺水臺(tái)地相過渡到深水陸棚、斜坡,最后到深水盆地相的地層格架與沉積環(huán)境解釋模式。
The transitional facies can also be divided as estuarine , tidal flat and lagoon ; the depositional envirnononents of clastic rock marine facies include offshore , shallow water continental shelf , deep water continental shelf , slop as well as the deep water basin ; the carbonate facies can also be divided into a carbonate platform and ramp 海陸過渡相又分為河口灣、潮坪、瀉湖;海相碎屑巖沉積環(huán)境包括濱海、淺水陸棚、深水陸棚、斜坡以及深水盆地;碳酸鹽巖海相又可分為碳酸鹽臺(tái)地、碳酸鹽緩坡。
