碳酸盐

This research has detail summed up the characteristics between aluminosilicate weathering and the weathering of carbonate rocks, and is pointed out the similar weathering processes for aluminosilicate and carbonate rocks at the second stage.

本研究工作系统地总结了碳酸盐岩和硅酸岩风化的特征异同，并且指出碳酸盐岩第二阶段的风化类似于硅酸岩的风化。

So the main aim of this thesis is to identify how much the paleo-oceanographic value of carbonate index is in the West Arctic Ocean.

所以，本文通过测定研究区样品的碳酸盐含量，来探讨研究区碳酸盐指标的古海洋学意义。

Thus, microbial carbonates should be classified within the limestones. Similar to reef rocks, microbial carbonates are frequently developed in strata from the Precambrian through to the Phanerozoic, in three forms: reef, biostrome and bioherm.

微生物碳酸盐岩，总体上构成生物作用类碳酸盐岩中的粘结岩类，以其明显的微生物作用特点而具有自己的分类体系；它不但作为生物礁岩石的主要类型，而且也常常以生物礁、生物层和生物丘三种形式发育在地层之中。

I say "could be converted" because regardless of the pH, there will always be some bicarbonate and carbonate present, but at some pH there are enough protons in solution that if they were combined with the bicarbonate and carbonate present, it would all be converted to carbonic acid.

我认为："可转换"，因为不论其ph值，也往往会有一些碳酸氢盐和碳酸盐，但在一些ph值有足够的质子的溶液中，如果他们有机地结合起来，与碳酸氢盐和碳酸盐结合，它都将转为酸性。

On the basis of it, fully utilizing reservoir prediction new means such as coherent data cube analysis and seismic attribute analysis etc. as to geophysical characteristic of fissure and carven development of carbonate reservoir and seismic reversion variation after hydrocarbon-bearing, combined with stress analysis, gradually summarized a set of auxiliary method of predicting the fissure and carven of carbonate reservoir to service exploration and development of the field.

在此基础上，根据碳酸盐岩储层缝洞发育及含油气后地震反射发生变化的地球物理特征，充分利用地震相干数据体、地震属性分析、特征参数反演等储层预测手段，结合应力分析，探索和总结预测碳酸盐岩储层的岩性和缝、洞发育情况的地球物理方法，用于油田勘探开发。

Fault zone is very clear in not only geophysical field but also seismic section, and it controls the development and distribution of sedimentary facies. On its downthrow, extension-depression basin develops, and on the upthrow, neritic carbonate platform or isolated carbonate platform develops, it is the structure--paleo-geography boundary of the two kinds.

断裂带在地球物理场和地震剖面上均有明显显示；并且控制了沉积岩相的发育、分布，表现为在该断裂北侧下降盘形成伸展裂陷盆地，上升盘一侧发育浅海碳酸盐台地或孤立碳酸盐台地，断裂带构成二者的构造-古地理边界。

Carbonate content is a mature and effective index for paleo-oceanography, but carbonate contents are commonly low in Arctic and so the study value is rebated largely.

在古海洋学研究中常用碳酸盐含量作为古海洋学研究的指标，但是北冰洋西部地区由于特殊的自然环境条件，使得沉积物中的碳酸盐含量特别低，以至于碳酸盐指标的应用价值受到了一定的影响。

According to the sequence model, the topography is expanse and flatness, there are relative shallow water, stable structure, flattened basement in intercontinental rifting basin, and the provenances changed gradually from terrigenous clasts to intra-basin carbonate. So, there are some corresponding characteristics in sequence genetic framework:① Sequence material components are carbonate rocks, and mixed sedimentary series of carbonate rocks and clastic rocks.

就层序模型来讲，陆内裂陷盆地地势宽缓，具有水体相对浅、构造稳定、基底平缓、物质来源由陆源碎屑逐渐向盆地内的碳酸盐转化，因此，其相应的层序成因格架具有如下主要特征：①在层序物质构成方面，主要由碳酸盐岩构成，其次是碳酸盐岩—碎屑岩的混合沉积岩系。

Based on the analyses of the three-dimensional distribution of organic matter abundance, organic matter type and organic matter maturation, the paper points out that the carbonate rocks of evaporite platform facies of O1m5 and O1m3 Member in the middle part of the basin are better source rocks.

通过对马家沟组碳酸盐岩中的有机质丰度、类型及成熟度在三维空间分布特征的研究，指出盆地中部马五段、马三段蒸发台地相碳酸盐岩为较好的烃源岩，盆地内其余地区和层位的碳酸盐岩为较差的烃源岩。

When the sandstones are surrounded by carbonates or thick mudstones, then high carbonate contents will be found in the sandstones.

当砂岩层围岩为碳酸盐岩或厚的泥岩时，在砂岩层内部易形成高碳酸盐含量、胶结作用强烈的含碳酸盐胶结物。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
