沉积

A glacial or alluvial deposit of sand or gravel containing eroded particles of valuable minerals.

Diamonds began growth when "Jiangnan continent" combined to Yangtze craton, the growth and residence average temperature T〓 was about 1200℃; Diamonds were mutil-stages growth and interruption caused by temperature and pressure varied during Yangtze craton activities; Diamonds were etched when the magma did not erupt on the surface and form failed magma in mantle; during the later growth term T〓＜1050℃, the type ⅠaA diamonds formed unclear and growth; Before the host magma erupted T〓＜0.5Ma, T〓A＜850℃, the type Ⅰb diamond formed unclear and growth; Few diamonds were brittle deformation during growth term, some were plastic deformation after growth; when the host magma erupted on the surface and weathered to alluvial deposit, diamonds surfaces formed green spots caused by irradiation, then most of green spots became to brown spots during a mid-temperature metamorphism; modern river reform it to alluvial deposit in the minute valley again.

在扬子地台&江南古陆&克拉通化时，金刚石开始生长，其生长与保存的平均温度T〓在1200℃左右；期间由于地台的活动，生长的温度压力条件发生了多次变化，使金刚石出现多次生长、停顿；夭折的母岩上侵活动使金刚石受到熔蚀作用；在金刚石形成的晚期，T〓值下降到1050℃以下，出现了另一次金刚石的生长期，在临近金刚石母岩上侵时T〓＜0.5Ma，温度进一步降到850℃以下，使Ⅰb型金刚石得以保存；在金刚石形成期间还有过碎性变形发生；金刚石形成后部分样品经过了塑性变形；金刚石在上侵过程中，遭受了强烈的熔蚀；在母岩露出地表，形成沉积砂矿时，受到了放射性物质的辐照，先形成表层的绿色斑点、壳层，后经过中低温的热变质作用，大部分绿色转化为褐色；现代河流作用对沉积砂矿进一步改造，形成现在的细谷型砂矿。

Sedimentary rocks form when sediments become pressed or cemented together or when sediments precipitate out of a solution.

沉积岩形成时，沉积物中，成为压或胶结在一起或当沉积物中沉淀出的一个解决办法。

It introduces the location, profile structure and environmental characteristic of lacustrine sediment and eolian sediment in detail. Stratum chronology is established during the last 5000 years based on radiocarbon, 210Pb and 137Cs dating method.

详细介绍了本研究野外考察获取的湖泊沉积剖面和风沙沉积剖面的地理位置、剖面结构及区域气候环境特征；在14C、210Pb和137Cs测年的基础上建立了近5000年沙地演化的地层年代序列。

The results illustrate that there has consistent alteration trends between the color of Tertiary sediments from Kuqa depression and Tertiary global temperature change.

结果表明，库车坳陷第三纪沉积物颜色变化与全球第三纪温度的变化有一致的趋势，随着全球气温的降低，沉积物的颜色的红色指数降低。

Combining sedimentary and structural geology methods together, this thesis studies the Triassic and Jurassic strata scattering in both basin and mountain area.

本次研究遵循沉积反演构造，构造控制沉积的思路，选取了西侧盆地区和东侧太行山区的三叠系和侏罗系进行了研究。

By comparison of long-term exposure with long-term immersion, the release amount of ammonium, nitrite, nitrate and dissolved phosphorus into the overlying waters from the sediments were increased during the reflooding after long-term dessication, reflecting that long-term exposure stimulated sediments as a releasing source of nutrient and accelerated the biogeochemical cycle of nutrient in the tidal flat ecosystem.

通过对比分析发现，长期暴露之后能够增加沉积物向上覆水体释放NH〓-N、NO〓-N、NO〓-N和TDP，显示了长期暴露加剧了沉积物作为营养盐的源效应，并且加速了潮滩生态系统内营养盐的生物地球化学循环过程。

It is a new cross-subject that combined modern seismic technology and sedimentology.

地震沉积学是继地震地层学和层序地层学之后出现的一门现代地震技术与沉积学相结合的新兴交叉学科。

Research on anastomosing river is in great demand of the geomorphology, hydraulic engineering and sedimentology.

网状河流作为一种新的冲积河流类型已经引起地貌学家、水利学家和沉积学家的关注，成为河流地貌领域、河流沉积领域以及河流水动力领域的研究热点之一。

Storm deposit constitute an important conception which was not put forward until the late 1970s, and it was considered as an great discovery in sedimentology.

风暴沉积是20世纪70年代后期才指提出的一个重要概念，被认为是沉积学理论的一次重大突破。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
