碳酸盐

Trees play an important role in the sequestration of atmospheric CO2 in magnesium and calcium carbonate rocks.

在二氧化碳结合成镁、钙碳酸盐的过程中，树木扮演着一个重要的角色：当山体增长，岩石会分裂开来，然后被运送到丘陵上，接着树木会使埋藏在泥土中的岩石分解成其他矿物，然后这些矿物就会跟空气中的二氧化碳结合。

The causes and mechanisms of fouling are studied based upon the field investigation and laboratory analysis,which show that the major components of the fouling are calcium and magnesium carbonates with calcium carbonate in large percentage.

结果表明污垢的主要成分为钙和镁的碳酸盐，其中主要是碳酸钙。

We reconstructed the change characteristics of the paleoclimate by the carbonate contents and the values of magnetic susceptibility.

It can be seen that the presence of the carbonate significantly increases the length of time required for sufficient magnetite oxidation to occur.

可以看出，该碳酸盐的存在大大增加了足够的时间长度为磁铁矿氧化所需的发生。

A rock containing clay materials and calcium and magnesium carbonates, with approximately the same composition as marl .

Mottles in leopard limestone have undergone rotational deformation and have certain preferred orientation,while the marly component shows distinct fea- tures of ductile deformation;it is r...

在露头尺度上，豹皮灰岩中的豹斑发生了明显的旋转变形并具有一定的定向性，而泥灰质成分则具有清晰的韧性变形特征，为较典型的碳酸盐糜棱岩；在微观尺度上，构成豹斑的白云石矿物未发生韧性变形，而泥灰质成分中的方解石具有明显的细粒化、拉长和定向。

According to the space distribution characters of tectonic-sequence-based lithofacies and paleogeography, it is showed that three types of hydrocarbon source-rock including carbonate rock, clay and coal in Permian mainly are developed in transgression and maximal sea flooding of two order sequences, and they deposite respectively on platforms with gentle slope in craton, in rift basins and around old lands.

构造-层序岩相古地理的空间展布特征表明，二级层序的海侵期和最大海泛期是二叠纪烃源岩发育的主要时期，分别在克拉通的缓坡台地上、裂陷槽盆和古陆周缘形成了碳酸盐岩、泥质岩和煤系三类烃源岩。

Based on field work in fourteen typical ore districts of China, the author made experiments on contact metasomatism of ultrabasic-acid intrusive rocks with carbonate rocks, interaction between volcanic pneumatolyto-hydrothermal solution and volcanic rocks, and metasomatism in the process of sedimentary metamorphism and migmatizatiun.

本文作者在全国14个典型矿区的野外工作基础上，进行了超基性-酸性侵入岩与碳酸盐岩的接触交代实验；火山气热液与火山岩的相互交代实验；区域沉积变质和混合岩化过程中的交代作用实验。

The CLIMAP 18k bp sediment data files were compiled by Oregon State University. The files contain micropaleontology in the form of faunal counts of diatoms, planktonic foraminifera, coccoliths, and radiolaria, as well as stratigraphy (percent fine, coarse, total carbonate, oxygen 18 and carbon 13), and geochemistry (percent opal, quartz, and organic carbon), and inferred sea surface temperatures for 635 ocean sediment cores.

此数据库的沉积物数据由Oregon州大学收集编制，包括硅藻动物群、浮游有孔虫目、颗石藻、放射虫目中的古微生物，以及地层中碳酸盐、氧18和碳13的百分含量和由635个海底沉积物钻芯样本推测得到的海面温度。

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。
