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，這些數(shù)據(jù)被局限在新生代成巖作用區(qū)域左邊自拍偷拍25页，氧同位素相對較低的比值可以認(rèn)為是后期變質(zhì)交待作用的結(jié)果狠狠cao2020高清视频。

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.

在新生代的沉積中，巖化作用在海岸地區(qū)的沉積物中發(fā)生的最快密黄片啪啪啪，這一地區(qū)海洋孔隙流體更多地與大氣水發(fā)生了混合欧美丝袜精品久久中文字幕，這一過程造成了碳氧同位素同步的發(fā)生減少。

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.

這些數(shù)據(jù)與想象的同位素漂移情況不一致人人操人人爱一区二区，有兩個因素應(yīng)當(dāng)考慮在內(nèi)黄色免费免费在线好看。1。碳酸鹽在δ13C存在負(fù)值漂移時沉積更加容易受到后期δ18O變質(zhì)交代作用的影響91精品熟女另类，這種影響與δ13C成比例久久久久久久久久久久久久久久久。2。海水δ18O與δ13C的同步減少使得數(shù)據(jù)出現(xiàn)在圖表上的近似新生代成巖作用區(qū)域欧美黄色网站视频免费1000，這種情況屬于偶然情況。
