ABP. Sedimentation rate is very low on the whole core and shows three apparent variations at three phases:① A comparatively high SR during marine isotope stage 3 (MIS3) and LGM, about 7.3 and 14cm/ka respectively;② A very low SR of 1.5cm/ka during the last deglaciation, which is different from the deeper Okinawa Trough with higher SR during the last deglaciation than the last glaciation;③ A negligible sediment accumulation since 6.4 cal.

A important conclusion is that fluvial-lacustrine, karst, diluvial, colluvial, glacial and outwash deposits, which formed between early Pleistocene and early middle-Pleistocene, have high cement degree, low permeability, high intensity, low deformation, and good engineering properties, but modern riverbed phase deposits, which formed in between late middle-Pleistocene and Holocene, are loose, highly permeable, weak, highly deformable and have bad engineer characteristics, so they are susceptive to differential settlement, piping, drafting, liquefaction problems.

Based on a review of the history of seismic stratigraphy, sequence stratigrapy, and seismic sedimentology, this paper discussed the status and future trend of the seismic sedimentology, and pointed out that 90° phase transformation and frequency division interpretation are just the two technical means rather than key techniques for seismic sedimentological studies.
结合地震地层学、层序地层学和地震沉积学的发展历程对地震沉积学的现状和趋势进行了探讨,认为90°相位转换和分频解释仅仅是地震沉积学研究的技术手段,而不是其关键技术;对于地震同相轴的穿时性问题,也仅存在于3级或4级层中,并且这种穿时性与"沉积物体分配空间"和"相异作用"有关。

TheJiyang depression located in paleomonsoon climate zone in the period of the sahejieformation sedimentation, the wet and hot climate made ancient lake become deeperwater, enhanced stratification, reduced primary productivity of plankton, decreasingsedimentary velocity of carbonate, increasing sedimentary velocity of clay, fortifiedreductibility on certain degree, and then would be available for development of blackshale, dark shale and oil shale; In the contrast, the cold and dry climate lead ancientlake to shallower water, subdued stratification, increaser primary productivity ofplankton, enhancive sedimentary velocity of aphanitic carbonate, decreasedsedimentary velocity of clay, and then would be available for development calciteshale, calcite laminar shale, calcite mudstone, shaly carbonate rock, even laminarcarbonate or dolomite rock.
济阳坳陷在古近系沙河街组沉积期属于古季风气候带,在湿热的气候条件下古湖水加深,分层性增强,浮游生物的古生产力降低,隐晶碳酸盐的沉淀速率变小,粘土沉积速率加快,还原性一定程度上有所加强,有利于黑页岩、油页岩和暗色泥岩的形成:而相对干冷气候下,古湖水变浅,分层性减弱,浮游生物的古生产力增高,隐晶碳酸盐的沉积速率变大,粘土的沉积速率减慢,有利于钙质页岩、钙质纹层页岩、钙质泥岩、泥灰岩甚至纹层状碳酸盐岩、灰岩的发育。

A schematic model was proposed to illustrate the occurrences of various lithologies and lithofacies associations. The erosional surfaces on siliciclastic mudstones, funnel-shaped structure, and the exhuming of massive cold-seep carbonates exposed might have been occurred concurrently during a tectonic unstable time in SW Taiwan. The deposition of fossiliferous mudstone interfingered with the conglomerate lithofacies, and represented the rapid facies transition from siliciclastic (non-carbonate) into carbonate environment.
综合岩相观察结果,建构一个符合台湾西南部更新世珊瑚礁与基底泥岩接触关系的沉积相模式;其中,基底泥岩顶部的不规则冲蚀面、充填碳酸盐胶结泥岩砾与碳酸岩烟柱的漏斗状沉积,以及块状冷泉碳酸盐岩的出露,可能均为区域地质构造活动时期所造成;至於与含化石泥岩同时沉积的砾岩相,可能均为基底泥岩在快速浅化的过程中所沉积,标志古环境由矽质碎屑快速转变为碳酸盐环境的过程。

The forward analysis of source rocks is defined as a method to estimate the amount of depositional organic matter or burial organic matter, and ulteriorly to estimate their original potential of hydrocarbon generation of source rocks by using the information of sedimentary environments, features of living biomass and physical chemistry in water medium through the geobiological analysis of geoecology, geomicrobiology, molecular geobiology and biogeochemistry. Quality and quantity of depositjonal organic matter can be calculated according to the productivity and preservation environrnents.

Beijing Institute of Cultural Relics and Archaeology,Beijing,China,100009Abstract The sedimentary characteristics and facies ofthe cultural layers in the late Paleolithic period of the late Late-Pleistocene in theWangfujing Oriental Plaza site were studied based on the comparison and analysis of thetypical sedimentation profile of the site and more than 150 stratigraphic data.The paleo-geomorphicsurfaces during the periods of 2.2×104a B.P.were rediscovered.The studysuggests that the ancients must have acted in the sandy islands of alluvial fans,whichwere evolved in relatively steady water flows during the interglacial stage with slightlywarming in the last glacial epoch.
