It is revealed from the analysis that the distribution, composition, lithofacies changes, and the formation mechanism and age of the relict sand are not consistent with the present depositional environment of this area.

它是在晚大理冰期最低海面后海平面不断上升过程中不同阶段的滨海相沉积，从冰后期海平面大规模上升以来，沉积作用在这些地区是微不足道的或者竟完全缺失，从而使砂质沉积直接裸露在海底表面，未被现代沉积所覆

This paper discusses the research carried out on the Lake Sugan, in the northern margin of Chaidam Basin. The climate and environmental changes in Lake Sugan drainage area over the past 2670 years were studied using the varve dating of the well preserved lamination sediments in core SG03I taken from the center of Lake Sugan, the study of varve formation in modern lake system and modern process study of carbonate and oxygen isotopes of the water within the drainage area, and according to the main index of the stable isotopes of carbonate sediments synthesized other index analysis.

本文以柴达木盆地北缘苏干湖为研究对象，通过对湖泊中心位置SG03I孔保存完好的纹泥沉积物岩芯进行年代学研究，对湖泊现代沉积过程及碳酸盐、流域水体同位素进行现代过程研究，以沉积碳酸盐稳定同位素指标为主，结合其它代用指标的综合分析，探讨苏干湖流域近2670年来的气候与环境变化，综合区域其它记录对苏干湖流域晚全新世气候变化的驱动机制进行探讨，获得如下认识：1、柴达木盆地北缘苏干湖若干钻孔岩芯发现，水深大于3.0m的沉积物均具有裸眼可分辩的由深色层和浅色层组成的纹层层理。

In order to select a perfective procedure and protocol for the fine grain OSL dating, measurements of natural IRSL and GLSL signals from a range of modern sediment samples collected from different sedimentary environment, tests of IRSL and GLSL bleaching behaviors for loess fine grains under sunlamp, and comparisons of the equivalent dose determined by different methods have been undertaken, as well as IRSL and/or GLSL dating of more than forty sediments samples taken from late Quaternary deposit strata at different site in North China.

为了选择更合适于中国北方沉积物样品细颗粒OSL测年的实验程序和技术，进行了华北地区不同沉积环境的现代沉积物样品的细颗粒天然IRSL和GLSL信号测量，黄土细颗粒IRSL和GLSL的光晒退测试，不同方法获得的等效剂量值的比较分析，以及取自华北不同地区的40余个晚第四纪沉积物样品的IRSL和GLSL测年。

Through fully digested available information and predecessor's cognition, using whisht and dynamic data acquisitied from each stage, making a refined known and interpretation for single reservoir sand, construct, collector, sediment etc in the oilfield. By dint of numerical reservoir simulation and producting history fitting for verification and adjustion.

通过现代沉积类比，在对取心井、大量电测资料和沉积微相研究的基础上，认为五2西克下组属于扇三角洲沉积体系，纵、横向上相变快，造成储层非均质性强。S_7~(42)为扇三角洲上分流平原亚相沉积；S_7~(41)为扇三角洲下分流平原亚相沉积；S_7~3扇三角洲内前缘亚相沉积；S_7~2、S_7~1均为扇三角洲外前缘亚相沉积。

By substantive field and indoor practice development work, this paper systemic researched the source, the sedimentary system, sedimentary facies, paleogeographic environment, under the guidance of sedimendary geology and petrolume geology theory.

论文通过大量的野外和室内的研究工作，结合现代沉积地质学和石油地质学理论，对鄂尔多斯盆地堡子湾地区延长组长6的物源方向及母岩性质、沉积相的确定标志及类型特征、古地理环境特征进行了系统全面的研究。

It has been established that modern evaporite mineral assemblages in this area. 8 saline minerals and 4 separate sinter minerals have been discovered.

现代含盐湖盆固相沉积的研究结果，发现了8种盐类矿物、4种泉华析出物，初步摸清了该区现代沉积与蒸发岩的矿物组合、湖盆演化现状，填补了本区含盐湖盆研究的空白。

Because of the low resolution of 〓C dating and the shortage of clear varves, it is very important for the high resolution dating of recent sediments to apply 〓Pb and 〓Cs accurately.

鉴于沉积物〓C测年的低分辨率和沉积物年纹理的缺失，准确地应用〓Pb和〓Cs计年法便成为我国湖泊现代沉积物高分辨率计年的关键。

The very low natural IRSL and GLSL signal levels of about 80-100 photo counts per second, corresponding equivalent dose of less than 1Gy, were presented for most modern samples, and imply that the IRSL and GLSL signal zeroing could be reached during deposition for most of loess and water-laid sediments in North China.

华北地区大多数现代沉积物细颗粒组分的天然IRSL和GLSL信号水平很低，约80-100光子计数/秒，相对应的等效剂量值小于1Gy。这可能表明，华北地区大多数黄土及水沉积物的IRSL和GLSL计时器在沉积过程中可能已基本&回零&。细颗粒IRSL和GLSL的光晒退实验结果也说明这一点。
