大沙漠

Although his tight schedule means he rather pelts through the continent, his eye for detail and his elegant pen give a flavour of each country he crosses: great veldts and high plateaux, Congo's "green vastness", the "sandy seas" of the Sahel and, finally, the fertile plain of the north African coast.

尽管行程非常紧张，只能对非洲大陆略知一二，但他观察仔细、形象地描述了经过的每一个国家，例如大草原、高原、刚果广袤的绿地、西非一望无际的沙漠，最后还有北非沿海肥沃的平原。

Bagnold was given a free hand to call for volunteers and decided early on to look for more robust colonial forcesthat were coming into theater, assuming they would be more self reliant than British Units.

By 1824, Jim Bridger and other mountain men explored the Great Salt Lake desert region.

His sketches of the wily desert chieftain Abram, the tongue-tied, reluctant Moses and cockily self-assured David are wonderful antidotes to the tired pieties of Sunday school.

在老谋深算的沙漠酋长亚伯兰舌头挂钩，不愿摩西和cockily自信他的素描是大卫周日学校的疲倦pieties美妙的解毒剂。

Recent field work has found that there are several terraces formed by water erosion of the dune sand in the transitional area bet-ween southeastem Ejina basin and Badain Jaran desert. The upper parts of these terraces were covered by the carbonate-solidified sandy crusts. They possess nearly the same elevation and are extensively correlatable.

新近的考察工作发现，在盆地东南部古日乃与巴丹吉林沙漠过渡区，存在有多级古沙丘被水夷平的、高度不等的平台，在这些平台之上，保存有水体快速蒸发环境条件下沙粒物质被钙质胶结的坚硬、类似砂岩的顶盖，其高度在大范围内可以对比，同时伴有湖相碳酸盐沉积、根管等。

The sand dunes analyses data have shown they mainly consist of well sorted, symmetry skewness and find sands, and the kurtosis peak is narrow or very narrow. There are abundant impacts of mechanic process on the surface of quartz grains. The traces of eolian process often superpose on the traces stamped by river and beach processes. The dish--shaped concavities and mechanic pits are the most common surface textures, but the barchan concavities and curved grain edges are indicated the marks by eolian environment. The heavy minerals assemblages of coastal dunes are dominated by relatively high specific gravity which have stable chemical properity suggesting the mordern high dynamic environments of coast area. The depositional structures of coastal dunes are typified by corss--bed sets composed of steep foreset laminates and gentle windward dipping sets. It also contains some shell fragments and strong worn foraminiferal tests that are impossibly found in inland desert. On the other hand, the sandy deposits of the continental shelf of East China Sea are with wide range of grains, and the depositional pattens are quite complicated.

海岸沙丘是晚全新世以来相对稳定的海平面背景下的海岸带风成堆积，其沉积特征是以细沙为主，分选好，搬运方式以跃移占绝对优势，偏度上近对称，峰态窄到很窄；石英颗粒表面机械作用形态丰富，风成作用形态叠加于河流和海滩过程形态之上，碟形坑和撞击麻点是最为常见的表面形态，而新月形坑和曲脊是其指示性的特征标志；沙丘沙重矿物以化学性质稳定、比重较大的种类为主，反映了海岸带目前的高能动力环境；海岸沙丘沙的沉积构造以高角度前积层和低角度顶积层组成的交错层理为典型特征，同时还含有少量内陆沙漠所没有的少量贝壳碎屑和强烈磨损的有孔虫壳体。
