海平面

The northern of basin is located on foreland uplift belt. The basin sequences represented overlapping of sea level and deep-upward series, with the foredeep transfer to north continually, whether is transgression or highstand stage.

而盆地的北侧的望谟-罗甸-紫云-贵阳一线处于前陆隆起带的位置，随着前渊凹陷的不断向北迁移，无论是在海侵还是高位期，均表现为海平面的上超和向上变深的序列。

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。

Scientists do not know why dinosaurs became extinct, but some theories postulate that *****gers in geography, climate, and sea levels were respONSible.

科学家不知道恐龙为何绝种了，但是一些理论推断是地理，气候和海平面的变化造成的。

Climate change expert Konrad Steffen, of the University of Colorado in the United States, explained the impact of climate-induced sea level rises to coastal areas.

气候变化专家康拉德的斯特芬在美国科罗拉多大学，阐述了气候变化引起的海平面上升对沿海地区的影响。

Our results indicate that the Malay Peninsula has had separate populations on opposite sides of the Kra Isthmus since its formation, but that interglacial migration at the Strait of Malacca may have provided a corridor for gene flow.

本研究结论指出在马来半岛形成后，有效阻隔克拉地峡两侧的族群，但在间冰期导致海平面上升，马来半岛南端麻六甲海峡的通道提供两海域生物长距离迁徙的路径。

During the interglacial period, approximately 5 Mya, sea levels rose and organisms migrated across the narrowest part of this peninsula, the Kra Isthmus.

然而，在古地质事件约五百万年前的间冰期，因海平面上升，使得马来半岛最狭窄的克拉地峡被海水淹没，原本分布在两个隔离海域的生物得以互相交流。

M. The lentiform deposits in the lower areas of the surface are bedded grainstone composed of microgastropods cemented by fibrous calcite.

这个侵蚀面代表一次显著海平面下降事件之后的一次较长时间的出露和风化剥蚀。

Now, Sr isotopes can be used not only to constrain the origin and evolution of magma and hydrothermal ore-forming solutions, calculate the scale and degree of lithogenesis and ascertain the relations between fluids and rocks, but also to study sea-level fluctuation, plate movement, ocean-floor spreading and lithogenic evolution.

现在，锶同位素不仅在示踪岩浆及成矿热液的来源和演化、计算晚期成岩改造作用的规模和程度及流体/岩石比等方面已趋于成熟，并且越来越广泛运用于海平面变化、板块活动、海底扩张、成岩演化等方面的研究。

For lithologic and stratigraphic traps, their origination might relate to sea level changes and folding.

岩性圈闭和地层圈闭的形成与海平面变化和褶皱运动有关。
