粘土礦物、碳酸鹽、粗碎屑、海域懸浮體、表層沉積物粒度趨勢分析、 poc c ~ ( 13 )及底質沉積物的c ~ ( 13 )等多方面研究表明:以黃海暖流為主導,南黃海堆積陸架平原西側現代沉積物陸源物質主要源於黃海沿岸流攜帶的現代黃河懸移物質,黃海槽東西兩側的沉積差異主要表現在冰消期以來沉積厚度、沉積層序、氧同位素記錄上。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。The sedimentary formation can be summarized as rift bay filling sequence, epicontinental sea filling sequence, offshore debris lake basin sequence and inner continental lake basin sequence. a framework of sequence stratigraphy for the upper palaeozic strata is established in the area. the helan aulacogen of upper carboniferous in the west margin of ordos can be divided into 12 sequences, and most of the upper palaeozoic strata in the area can be divided into 15 sequences
本文對研究區內上古生界進行了層序地層學探討,將本區沉積建造概括為裂陷海灣充填層序、陸表海充填層序、近岸碎屑湖盆層序和內陸湖盆層序,建立了研究區上古生界層序地層學格架,西緣賀蘭拗拉槽上石炭統劃分為12個層序,本區大部分地區上古生界可劃分出15個層序,並全面地概括了層序演化各階段的具體特徵。Based on the new structural framework and the overlap relationships in every continuous outcrop, the new stratigraphic sequence of the yanbian group is put forward, which deeply changes the rock composition of every formation
根據新的區域構造格架和野外連續露頭的疊覆關系,重新釐定了鹽邊群碎屑巖的地層序列以及各碎屑組的內含。The formation and evolution of the sequence stratigraphy of the yanchang formation are governed by slow tectonic subsidence, warm humid climates, sediment supply and lake - level fluctuations
延長組層序地層的形成與演化主要受控于當時緩慢的構造沉降、溫濕氣候、陸源碎屑物源供給及湖平面升降等地質因素。It is considered that the sequence evolution in the palaeozoic went through the following three stages, the filling of evaporate platform, the filling of carbonate and detrital rock mixed deposits in epiric sea, and the filling of detrital deposits of lake - deltas in paralic inland sag
認為研宄區古生界層序演化經歷了以下三個階段:蒸發臺地充填階段、陸表海碳酸鹽巖與碎屑巖混合沉積階段,以及近岸內陸坳陷的湖泊三角洲碎屑巖沉積階段。It is suggested in this paper that the sediment of the high stand system tract is mainly composed of fine - grained sediment, hardly of the large scale of fluvial - delta because of the low dip of the ramp, low subsiding rate and low sedimentary rate in basin
研究表明,盆地基底沉降幅度小、坡度極為平緩、沉積速率很低,因此導致層序內的高位體系域多以細碎屑沉積為主,大型河流三角洲沉積基本不發育。From csql to csq5, the barrier system was the main system. from psql to psq5, the carbonate ramp was the main system and from psq6 to psq8 the main system was fluvial and fluvial - delta system in brackish basin. from psq9 - psql2, the main system turned to the fluvial - delta system
