Under the guidance of theories of sedimentology , petroleum geology and sequence stratigraphy , and through the comprehensive analysis of outcropsrock , cores , well logs and testing outcomes of rock gas , this paper studies the depositional systems of neopaleozoic and the character of aeration zone in tabamiao area of ordos basin . the result indicates that the object layers are divided into two depositional systems , the barrier seacoast depositional systems are recognized on upper carboniferous taiyuan phase with tidal flat , lagoon and barrier bar sedimentary deposit 本文根据沉积学、石油地质学和层序地层学理论，综合利用地表露头、钻井岩芯、测井曲线资料和试气成果资料，对鄂尔多斯盆地塔巴庙区块晚古生代沉积体系及含气层特征进行了研究。结果表明，研究区内目的层段可以划分为2个沉积体系： ( 1 )上石炭统太原期为有障壁海岸沉积体系，发育潮坪?泻湖?障壁砂坝沉积。
On the basis of depositional studying of single well , concluding lithofaces - paleography of every formation : yeli - liangjiashan formations deposit in restrained sea ; lower majiagou formation early in tidal flat and late in restrained platform ; upper majiagou formation early in tidal flat and late in open sea ; fengfeng formation early in tidal flat and late in open sea 指出冶里组?亮甲山组以局限海沉积为主，早马家沟早期潮坪发育，晚期为局部台地，晚马家沟早期仍有广泛的潮坪发育，晚期则以开阔海为主，峰峰期早期潮坪广布，晚期则以广泛发育开阔海为主。
Abstract : according to sedimentary characteristics of the carboniferous taiyuan formation in feicheng coal field , including lithology , size distribution , sedimenta ry structure , geochemistry and paleontology etc . , the carboniferous paleoenvironme nt of this area is divided into carbonate open platform and tidal flat environme nt . it is recognized that the taiyuan formation is formed in the epicontinental c oast which is dominated by the tidal . the peat flat is the important paleoenviron ment for coal accumulation . the tidal channel destroys the coal bed . the pulsative vibration of the crust is the major factor which controls the evolution of the sedimentary environment and the coal accumulation 文摘:根据肥城煤田石炭系太原组的岩性、粒度分布、沉积构造、地球化学及古生物等沉积特征，将该区晚石炭世古地理划分为碳酸盐开阔台地和潮坪环境，认为太原组形成于潮汐作用为主的陆表海海岸，泥炭坪是成煤的重要古地理环境，潮渠对煤层有一定的破坏作用，地壳的脉动性振荡作用是控制沉积环境演化和聚煤作用的主要因素。
2 . the new idea about classification of oil and gas accumulation unit for exploration have been put forward , which holds the sound basis for the perpendicular and plane position and prediction of carbonate reservoir in feixianguan guan group . 3 . the depositional systems of feixianguanguan group in taphrogenic consist of carbonate platform facies ( include oolitic bar , oolitic beach , lagoon , flats ) , margin shelf and trough . there are five development staged in taphrogenic trough 3 、指出裂陷槽中飞仙关组沉积体系在平面上由碳酸盐岩台地相(包括滩坝相、鲕滩相、泻湖相、潮坪相) 、陆棚相、裂陷槽相组成，裂陷槽经历了发生期、发展期、稳定期、过渡期及衰亡期五大发展演化阶段，每一阶段各发育不同的沉积相，且以一种沉积相为主。
Based on the direction of sources and the ratios of sandstone to formation of sedimentary rocks , together with the sedimentary structures and textures , paleocurrent direction and the characteristics of paleontology , etc . , the planimetric maps of sedimentary facies of each stages in the studied area are compiled in order to recognized the extension of dominant facies and the evlotionary history of sedimentary environment , hi the stage of benxi and taiyuan , lagoon - tidal flat sediments are widespread in the area , and the deposits of estuary , lagoon and small delta in the northwest margin of ordos 以物源方向和沉积岩砂地比值为基础，结合沉积结构构造、古水流方向及古生物特征等，编制了研究区各期次的沉积相平面图，以识别优势相展布和沉积环境演化。本溪期和太原期研究区泻湖?潮坪沉积分布广泛，西北缘发育河口湾、泻湖及小型三角洲沉积。
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。
Phosphate deposits are distributed along the margin , platform and basin in the west yangtze area . the analysis methods include the paleogeography , petrology , organic geochemistry , geochemistry . the conclusions are drawn that the source of phosphate deposits distributed along the margin originate from the weathering production of continent , while phosphate deposits along the platform and basin gain phosphorus through hot spring on the buttom of the sea floor , which is brought to the sedimentary environment by rising sea - fluid , then accumulated by the organism and microorganism , meanwhile , basin phosphorite keep relatively higher organic carbon content 认为早寒武世早期古陆遭受风化，被剥蚀下来的产物成为潮坪型磷块岩的主要磷质来源，在碳酸盐岩台地发生的热点活动和上升洋流从盆底深部带来的磷质，共同作为台地型磷块岩的磷源，盆地型磷块岩的磷质同样是由热点活动和上升流携带至缺氧的沉积环境中，通过藻类或微生物的富集作用成岩，并保留了较高的有机碳含量。
( 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。
