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 海陆过渡相又分为河口湾、潮坪、泻湖；海相碎屑岩沉积环境包括滨海、浅水陆棚、深水陆棚、斜坡以及深水盆地；碳酸盐岩海相又可分为碳酸盐台地、碳酸盐缓坡。
By comparing with the strata of " holocene series of the coastal plain of laizhou bay " and combining 14c age measurement , the strata position and features of the lagoon ? hallow sea ? each sedimentary facies are confirmed . the stratigraphic division of upper marine facies of holocene is done and the sedimentary environment of every stratum is affirmed 通过与“莱州湾滨海平原全新统”进行地层对比并结合~ ( 14 ) c测年数据，确定了该沉积区全新世泻湖?浅海?海滩相沉积层的层位和特征，并对该层及其以上地层进行地层划分，判断出各层的沉积环境。
( 2 ) based on the two important sections of yanshiping and yicangma , a study is conducted on the sedimentary features and facies of middle - upper jurassic series , it is suggested that quemo formation is river - delta facies deposit , buqu formation is chiefly carbonate ramp facies deposit , xiali formation is delta - tidal flat facies deposit , ? suowa formation is mixed shelf - lagoonal facies deposits and xueshan formation is river - delta facies deposit ( 2 )以雁石坪和依仓玛两条重点剖面为基础，开展了中?上侏罗统沉积特征、沉积相等方面研究，认为研究区雀莫错组为河流?三角洲相沉积，布曲组以碳酸盐缓坡相沉积为主，夏里组为三角洲?潮坪相沉积，索瓦组为混积陆棚?泻湖相沉积，雪山组为河流?三角洲相沉积。
It is suggested that the distribution of the depositional systems and the depositional facies have the clear characteristic that in the north of the research area , the alluvial fan sediment , the fluvial system and the delta system are the main styles of the depositional system , towards to the direction of basin the lacustrine , the barrier , the carbonate ramp system become the main depositional systems 受海平面升降变化控制，区内沉积体系和沉积相的分布具有明显的分带性，北部靠近源区以冲积扇或河流及三角洲沉积为主，向盆地方向以湖泊或海岸障壁-泻湖、碳酸盐缓坡沉积为主。中二叠世北部源区发生构造抬升，当时古气候逐渐干燥，成煤环境结束，沉积物以陆相河流、湖泊三角洲占优势。
Furthermore , sixteen sedimentary subfacies are identified . respectively , the sedimentary subfacies are delta plain , delta front , prodelta , braided delta plain , braided delta front , braided prodelta , coastal lake , saucer lake , tidal flat , barrier island , lagoon , carbonate continental shelf , muddy continental shelf , open platform , local platform and evaporate platform 并进一步识别出16种沉积亚相，分别为：三角洲平原、三角洲前缘、前三角洲、辫状河三角洲平原、辫状河三角洲前缘、前辫状河三角洲、滨湖、浅湖、潮坪、障壁岛、泻湖、碳酸盐陆棚、泥质陆棚、开阔台地、局限台地和蒸发台地。
