自生矿物

At the same time, the SEM study shows that gibbsite occurs on the sample surface. At 200 ℃, as dawsonite sandstone is being dissolved authigenic siderite forms. At 300℃, chlorite deposit on parts of the sample surface. The weak solution of dawsonite sandstone at 100℃ and the formation of siderite at 200℃ illuminate that CO2 being in carbonates in the strata can not be released when CO2 phase is adding to the system.

同时，各温度下样品表面均有一水软铝石放射状集合体沉淀。200℃时，随着片钠铝石的溶解有自生菱铁矿生成，300℃时样品局部有绿泥石沉淀。100℃下片钠铝石的微弱溶解及200℃下菱铁矿的形成表明，在地层条件下以碳酸盐矿物形式捕获的CO2，不会由于CO2的二次注入而重新释放。

The relationship between the formation of some typical mineral (the authigenic pyrite and the ferruginous carbonate ) and hydrocarbon is discussed in this paper, based on the correlation of stratigraphic features and diagenetic mineral in different structural belt in the Member 3 of Shahejie Formation from Dongying Depression.

针对自生黄铁矿-碳酸盐矿物-自生石英矿物组合，提出了示烃球的新认识并将其分为两大类，I型示烃球主要分布于含油性较好层段，II型示烃球主要分布于烃类活动相对较弱的非含油层段。

根据自生粘土矿物的组合特征，可以有效地确定碎屑岩的成岩阶段及其孔隙发育特征。

The diagenetic stage and pore-evolution properties of clastic rock can be effectively determined according to the assemblage of authigenic clay mineral.

根据自生粘土矿物的组合特征，可以有效地确定碎屑岩的成岩阶段及其孔隙发育特征。

The formation and conversion of authigenic clay mincral were dominated by initial mineral components and diagenetic environment of clastic rock.

自生粘土矿物的形成和转化取决于碎屑岩原始矿物组分及其成岩环境。

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。

Based on the study of rock textures and structures, and stable isotopes of dolomite and S isotope of barite interlayers within the cap dolomite outcropped in the Miaohe area in the Three Gorge, it is testified that the stable isotopes show a strong negative excursion, and the isotopes of sulfur show a significant positive excursion, which is similar to the reported data of authigenic barites formed in a modern seafloor gas hydrate environment. Therefore, it can be concluded that the cap dolomite was most likely formed in a special environment under which a huge gas hydrate dissociated with the breakup of "Snow Earth" in later Neoproterozoic.

通过对湖北三峡庙河地区出露的&盖帽&白云岩的野外地质构造、碳－氧稳定同位素和重晶石夹层的硫稳定同位素特征的研究，发现除了明显的碳稳定同位素的负偏移之外，重晶石的硫同位素值表现出明显的正偏移，其数值可与现代海底甲烷喷气孔附近的自生重晶石矿物的同位素组成相对比，进而认为&盖帽&白云岩的成因是末元古代&雪球&事件之后天然气水合物的释放与全球环境突变背景下的沉积产物。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
