沉积

Using the data and samples of the holes DSDP218,ODP717,ODP758 and some others from the northern Indian Ocean,in the paper we make a comprehensive study of them in sedimentology,micropaleontology and paleoceanography and establish a correlation of geological events since 9 million years recorded in proximal fan,distal fan and ridge,respectively.

本文应用DSDP218、ODP717、ODP758及其它来自东北印度洋的资料和样品，通过沉积学、微古生物学与古海洋学的综合研究，实现了9 Ma以来扇区近源相、远源相和岭区沉积记录中的事件对比。

The CLIMAP 18k bp sediment data files were compiled by Oregon State University. The files contain micropaleontology in the form of faunal counts of diatoms, planktonic foraminifera, coccoliths, and radiolaria, as well as stratigraphy (percent fine, coarse, total carbonate, oxygen 18 and carbon 13), and geochemistry (percent opal, quartz, and organic carbon), and inferred sea surface temperatures for 635 ocean sediment cores.

此数据库的沉积物数据由Oregon州大学收集编制，包括硅藻动物群、浮游有孔虫目、颗石藻、放射虫目中的古微生物，以及地层中碳酸盐、氧18和碳13的百分含量和由635个海底沉积物钻芯样本推测得到的海面温度。

Firstly, the effects of electrodeposition parameters such as the electric current density, the initial molality of ZnSO4/Na2SeO3, the pH value, the quality of sodium citrate, the time of electrodeposition, the temperature and the ultrasonic power are discussed.

讨论了电流密度、初始浓度比c(ZnSO4：c(Na2SeO3)、pH值、柠檬酸钠加入量、电沉积时间、电沉积温度以及超声功率对镀层的影响。

The result indicates that Chang 6^2 is a delta-lacustrine depositional system, and the principal producing pay is in subaqueous distributary channel where deposit fine sandstones and have good physical properties. The areas in the center of subaqueous distributary channel get high oil-produce while the flanks gel lower oil-produce relatively. The distribution of oil layer is mainly controlled by lithology, and Chang 6^2 is lithologic reservoir developed in the monocline setting which clime to the northwest.

研究表明：长6^2储层为三角洲－湖泊沉积体系，主要产油层位于长6(上标 2-2)的水下分流河道中，沉积细砂岩且物性较好，河道中心地区的产油量相对较高，而河道侧翼地区的产油量相时较低：长6^2中的油层分布主要受岩性控制，是在北西倾料的单料背景上发育的岩性油藏。

The results showed that there were remarkable seasonal variations of chlorophyll a concentrations and grain size at the surface of the mudflat, i.

结果表明，研究区域表层沉积物中叶绿素a的浓度4，5月份较高，分别为(5.997±0.803)gg^(-1)和(2.356±0.295)gg^(-1)，12月份最低，为(0.571±0.091)gg^(-1)；表层沉积物中细颗粒物质(0m)含量从4月到12月也有减少的趋势，春季4月份最高，为(91.0±5.44)%，冬季12月份最低，为(59.8±11.95)%。

Main recognition bases of the Gangdisê multiple island arc-basin system are:① tectonic pattern of collisional zones and island arc or landmass as strips alternating with blocks;②development of multiple arc volcanic-intrusive zones due to consumption of back-arc basin and arc-arc collision;③complicated paleogeographic and paleotectonic patterns shown by numerous sedimentary basin types and sedimentary facies association.

冈底斯构造带多岛弧—盆系统识别的主要依据有：①构造带中发育碰撞结合带与岛弧或陆块呈条块相间的大地构造基本格局；②发育多条由弧后盆地衰亡和弧—弧碰撞作用而形成的弧火山—侵入岩带；③众多的沉积盆地类型和沉积相组合，反映出冈底斯构造带具有复杂的古地理和古构造格局。

Little difference of surface sediment grain size was showed between spring tide and neap tide, and the difference of mean diameter was about 9.7%.

表层沉积物大小潮变化较小，两次采样平均差别为9.7％；沉积物年际变化随大通流量和输沙量的变化而变化。

The results suggest that there had been sediments of Late Oligocene and Neogene,but all were denuded.

三水盆地华涌组应用此方法分析的结果为渐新世晚期及新第三纪有过沉积，只是沉积后又被剥蚀殆尽，致使现今无地层记录。

For the past few years, oil and gas exploration of Neogene in depression have obtained remarkable achievements and has been paid more and more attention. Therefore, the research on sequence stratigraphic framework, and tectonic control action on depositional system in syndepositional-faulted basin has great significance.

论文从层序地层格架入手，深入分析层序地层以及同沉积断裂活动对沉积体系充填的控制作用，预测储集砂体的空间分布，对陆相断陷湖盆的层序地层学研究和黄河口凹陷新近系的油气勘探具有重要的理论和生产意义。

The four hiatuses recognized together at least 3 Ma of the late Oligocene sediment record.

主间断面位于 2 5Ma ，亦即滑塌沉积层的底界。4次沉积间断总共造成至少 3Ma沉积记录的缺失。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
