作为青藏高原以北最宏伟的活动陆内造山带，天山成为揭示中亚地区岩石圈结构的关键，同时也是研究中亚地区晚新生代陆内变形、造山成盆地球动力学过程的窗口。

The characters of geochemistry are rich alkali. And at the same time the content of calcium is high. They are rich in alkali, high in Potassium, enriched in LILE, LREE and Pb, depleted in HFSE and have a small Sr, Nd, Pb isotope range. Their source is probably a kind of even metasomatic mantle. This is consistent with the fact that there is kimberlite containing flogopite in the deep-source enclosure of Cenozoic super-K alkali lava in the southern part of this rock zone.

组成这些钾质碱性岩带的岩石：在岩相上，包括深成相、浅成相和喷溢相等不同岩相；在岩性上，从超基性、基性、中性到酸性岩石；造岩矿物，从超基性到酸性岩石中均有透辉石，在基性、超基性岩中有霞石；在岩石化学成分上，所有岩石均表现出富碱高钾富钙，微量元素富集Rb、Sr、Ba等大离子亲石元素和Th、U等放射性元素，贫Nb、Ta、Zr、Hf等高场强元素；稀土元素富集轻稀土，铕负异常不明显；Sr、Nd、Pb同位素组成，显示了物质来源于富集地幔源区。

There developed many red detrital laterite strata named as red-bed in the Cenozoic stratum of the eastern China oilfields.

在我国东部油田的新生代地层中，多发育大套的红色碎屑岩地层，其中发育有很好的油气藏。

The Cenozoic kamafugites in Lixian County of West Qinling are poor in SiO2 and A12O3 but rich in MgO, CaO, TiO2 and K2O+Na2O. The modal mineral assemblage is composed mainly of olivine, clinopyroxene, nepheline/kalsilite, melilite/leucite and Ti-phlogopite.

西秦岭礼县地区新生代钾霞橄黄长岩係具有贫SiO2、Al2O3，富MgO、CaO、TiO2及K2O+Na2O的特徵，矿物组合中除橄欖石、透辉石外，普遍含有霞石／钾霞石、黄长石／白榴石和鈦金云母等矿物。

Cenozoic basalts in Yangyuan, Hebei, located in the west of the Daxing′anling-Taihangshan gravity lineament, contain abundant peridotite and pyroxenite xenoliths.

位于大兴安岭-太行山重力梯度带西侧的阳原新生代玄武岩中含有大量橄榄岩和辉石岩包体。

In Cenozoic rocks, its position in the crossplot would indicate that meteoric waters rich in coastal photosynthetic C were a component of the pore fluids during lithification.

这些新生代的岩石在图1中的位置显示大气水在海岸富集了大量的光合作用碳同位素，这些同位素代表了成岩过程中的孔隙流体的组成。

2B–f. Instead, they are bounded by the Cenozoic lithification domain to the right, and stream off to lower δ18O values that are readily attributable to later metamorphic alteration.

相反的，这些数据被局限在新生代成岩作用区域左边，氧同位素相对较低的比值可以认为是后期变质交待作用的结果。

On the basis of studies of Cenozoic deposits, lithification is most rapid in sediments in coastal areas where meteoric ground waters mix with marine pore fluids. The process yields a roughly co-variant relationship between δ13C and δ18O in which δ13C decreases as δ18O decreases Fig.

在新生代的沉积中，岩化作用在海岸地区的沉积物中发生的最快，这一地区海洋孔隙流体更多地与大气水发生了混合，这一过程造成了碳氧同位素同步的发生减少。

These data are incompatible with the excursion scenario unless (1) carbonates deposited during a negative δ13C excursion are more susceptible to later δ18O metamorphic alteration in proportion to their negative δ13C value, or (2)δ18O of sea water decreases as δ13C of sea water decreases to produce an array that fortuitously resembles the Cenozoic lithification domain Fig.

这些数据与想象的同位素漂移情况不一致，有两个因素应当考虑在内。1。碳酸盐在δ13C存在负值漂移时沉积更加容易受到后期δ18O变质交代作用的影响，这种影响与δ13C成比例。2。海水δ18O与δ13C的同步减少使得数据出现在图表上的近似新生代成岩作用区域，这种情况属于偶然情况。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
