粘土矿物和碳酸盐矿物的转化对烃源岩力学性质产生了影响，导致随埋藏深度的增加岩石由相对塑性向相对脆性转变。

Phanerozoic examples of carbonate in dominantly clastic sequences also display wide variations in δ18O and δ13C Fig.

显生宙主成分为碎屑岩的碳酸盐样品也显示了较大范围的碳氧同位素变化。

On basis of measurement of homogeneous temperature of inclusions, analysis and calculation of δ〓C and δ〓O, and SEPM analysis, the author has studied the forming temperature of authigenic quartz and carbonate minerals for the first time. Furthermore, the author points out that it is unreasonable to recover paleo-geothermal gradient directly using homogeneous and modern burial depth.

作者在包裹体均一温度测量、碳氧同位素测量和计算及电子探针分析的基础上，首次对吐哈盆地侏罗系自生石英和碳酸盐矿物的形成温度进行了研究，确定了这两种成岩矿物的形成温度，并指出直接用包体均一温度和地层现埋深恢复古地温梯度存在不合理性。

This is attributed to the infuence of the difference in carbonate mineralogy in different sedimentary environments on the Sr distribution and also to the diagenetic environment which depends upon the sedimentary environment.

究其原因，一方面因不同沉积环境中碳酸盐矿物组分不同，影响了锶的分布；另一方面与沉积环境所决定的成岩环境有关。

在西太平洋的—系列边缘海盆中，南海发育有四个规模巨大的现代碳酸盐台地，即东沙、西沙、中沙和南沙碳酸岩台地，这是南海新生代地层的重要特征之一。

The hydrothermal circulation depth is between 898 m and 2192 m.(2) The hydrochemistry of geothermal water in Taiyuan is controlled mainly by carbonatedissolution and mixing between cold water and hot water.

各岩溶水系统补给区的Ca~(2+)、Mg~(2+)、HCO_3主要是由碳酸盐和白云岩溶解生成，排泄区的Ca~(2+)则有其他来源，即径流过程中石膏的不断溶解而成。

The cycles form part of a karstied carbonate-ramp sequence that is overlain by, and grades basinward into, siliciclastic turbidites.

该旋回在碳酸盐层序形成部分喀斯特，上覆向盆地方向进积的硅质碎屑浊积岩。

Comparing and analyzing of the paleoceanography characters from the SST, SSS, paleoproductivity, carbonate dissolution, paleo-monsoon and throughflow actions, we find it is obvious that the ocean currents system difference between the glacial and deglacial.

通过不同洋流区的岩芯末次冰期以来的古水温、古盐度、古生产力、碳酸盐溶解作用、古季风、穿越流活动等古海洋学特点的对比分析，可看出研究区冰期与冰后期海洋环流特点存在着明显的差异。

There are two different opinions on origin of gases in Ordovician reservoir of the central gas field of Ordos basin:(1) Gases are mainly sourced from Ordovician carbonate source-rock, it is a mixed gas in which sapropelic gas dominates;(2) Gases are mainly sourced from Carboniferous coal-bearing source-rock, it is a mixed gas in which humid gas dominates.

对鄂尔多斯盆地中部气田气源问题主要有两种不同看法：一种看法认为它是以奥陶系碳酸盐烃源岩来源为主、腐泥气为主的混合气；另一种看法认为它是上古生界煤系气或煤系气为主的混合气。

The secondary pores of the sandstones were formed by the dissolution of the aluminosilicate, tuffaceous interstitial material and carbonate minerals effect by the carbonic acid and organic acid produced in late diagenesis stage. Hydrocarbon emplacement and tectonic thermal event act a positive role in the preservation of the primary pore and the formation of the secondary pores.

砂岩次生孔隙主要是成岩晚期阶段的碳酸以及有机酸对长石等硅酸盐矿物、凝灰质填隙物以及碳酸盐矿物的溶蚀造成的，油气侵位及构造热事件对原生孔隙的保存及次生孔隙的形成起到了积极作用。
