Benthic foraminifer fauna, ams14c dating and acoustic sub - bottom profile was analyzed in the core ey02 - 2 and ey02 - 1 drilled from the muddy deposit in the middle southern yellow sea and the mid - shelf of north east china sea. considering the results of core qc2 ? dz4 and the standard oxygen isotope curves, we discussed the late - quaterenary paleo - environment evolution, benthic foraminifer fauna, paleo - climate, the climate events and water mass in postglacial period, average sedimentation rates, paleo - water depth, origin of sediments, average sea level rise rate in the shelf of south yellow sea and east china sea. at last we discussed the condition of sea level rise in the east china, green house effect and the protection of coastal zone
本文根據南黃海中部泥質區和東海中陸架的兩個鉆孔巖芯的古生物、 ams ~ （ 14 ） c測年、淺地層剖面等，參考qc _ 2 、 dz _ 4成果及標準氧同位素曲線探討了黃東海陸架晚第四紀古環境演化、底棲動物群特徵、古氣候、冰後期以來氣候事件、古水團、沉積速率、古水深、沉積物源、海平面平均上升率，討論目前中國東部海平面上升的狀況、溫室效應及海岸帶保護。 -
In a way, the evolution to upward of distributary channel microlithofacies in shelf delta plain of later carboniferous epoch in this area is repeatedly and rapidly, and every time is a normal grading change from coarse to thin, at last it evolve into marshy deposit
應用馬爾柯夫鏈分析方法得到的結果是，本區石炭統上段礫石質三角洲平原分支流河道的微巖相旋迴的向上演化，是重復而迅速的，每次都是由粗到細的正旋迴，最後演化為沼澤沉積。 -
The lower paleozoic continent marginal sedimentary strata in the north kunlun massif are sinian - cambrian alajiaoyi group and ordovician pishigaisayi formation. the former is composed of high maturity flysch deposit, the later consist of continental shelf deposit such as carbonate and slate and sandstone. these rocks implies that they might form at passive continental margin
與其曼于特蛇綠巖相關的早古生代邊緣沉積巖在昆北地塊上為震旦?寒武系阿拉叫依巖群、奧陶系皮什蓋薩依巖組，前者為一套成熟度較高的陸源碎屑復理石沉積，後者為碳酸鹽巖和含碳板巖砂巖等陸棚沉積，顯示其具被動陸緣性質。 -
( 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
