Influenced by tectonic movement, there were no sediments in the area from Oligocene to Miocene. Appearance of marlite in the Pliocene, especially in Yaqueling region, proved localized depositing environment forming, for which there had only few amount of terrigenous matters to supply. Sedimentary facies association of alluvial fan, fan delta and inland lake appeared at the early and middle stage of lower Pleistocene, and association of fan delta and inland lake appeared at the later stage of lower Pleistocene and the early stage of middle Pleistocene. Net-veined laterite appeared at the top of lacustrine deposit, which reflected pedogenesis taking place after the end of deposition. Such evolution history proves that there had no lager river system traversing this area before the early stage of middle Pleistocene.

对于江汉盆地西缘宜昌地区来说，其沉积及古地理演化表现为：早白垩世为受天阳坪断裂控制的内陆湖泊沉积环境，沉积中心在天阳坪断裂的北侧，此时几乎不存在来自黄陵地区的水系；晚白垩世同样为受断裂控制的内陆湖盆环境，但湖盆面积扩大、断裂活动减弱，且后期出现成化湖相沉积；第三纪早期盆地由断陷盆地转变为坳陷盆地，同时石膏的出现代表了局限咸化湖盆的存在；渐新世—中新世，受构造影响，缺失该时期的沉积；上新世时在鸦鹊岭一带出现的泥灰岩沉积反映了陆源物质供应不足的局限沉积环境的存在；早更新世早中期为冲积扇—扇三角洲—内陆湖泊沉积，早更新世晚期—中更新世早期为扇三角洲—湖相沉积，后期出现沉积结束以后的网纹红土化作用。

This study, based on the Biolog method and with analysis of principal components and diversity index, provides a comparison and analysis of the microbial metabolism in sediments from this area.

This study shows that micropaleontology is significant in the research of deltaic or tidal sediments .

在三角洲与潮坪研究中，微体古生物学发挥了重要作用，而不仅是记述内容之一。

The magnetite compositions of the Changjiang River sediments were analyzed by electron microprobe.

运用电子探针分析了长江干流和主要支流河漫滩沉积物中磁铁矿的元素组成。

Antonie van Leeuwenhoek, pioneering microscopist, observed in 1702 that dry sediments of "animalcules", expected to be dead, were brought back to life when exposed to rain water.

安东尼·范·列文虎克——使用显微镜的先驱，在1702年观测发现，把被认为死亡了的干枯的"微生物"沉积物放在雨水中时它们又复活了。

L Slate - Soil type that is the most common found in the Mosel region that is a dark gray, plate like rock that formed when clay, shale, siltstone and other sediments are subjected to pressure.

l 板岩-一种深灰色、扁平状的岩石，由粘土、泥板岩、泥沙岩和其他沉淀物受压力形成。在默塞尔地区非常常见。

The temporal change in floes size of fine suspended sediments was measured in Xuliujin of the Changjiang Estuary in June of 2003, by using an in situ laser diffraction particle sizer, the laser in situ scattering and transmissomerty-100(LISST-100). The spectrum analysis was applied to analyze the fluctuation of floes diameter during the spring tide and the neap tide.
