oxygen isotope method

Through testing 45 carbonate samples collected from PermoCarboniferous caol measures of the Hedong coalfield,the distributions characteristics of carbon and oxygen isotopes in sequences are analyzed,whose feasibilities for sequence subdivision and correlation,as well as for study of relative sea level variations and late Paleozoic facies are also discussed.

系统分析了河东煤田上石炭统（Ｃ２）—下二叠统下部（Ｐ１１）４５个碳酸盐岩样品的碳氧同位素在层序中的分布特征，探讨了碳氧同位素应用于层序划分及对比、相对海平面变化研究及晚古生代地层沉积相研究的可能性。

They are among the few minerals that show mass independent fractionation of oxygen isotopes.

硫酸盐不仅是常见矿物,还是自然界少数几个具有氧同位素非质量分馏效应的矿物之一。

In order to analyse the regulation of past global changes in the low latitude and high elevation region,based on the fundamental of the high precision and high resolution thermal ionization mass spectrometry uranium(TIMS-U) series dating and the oxygen isotopes,taking a stalagmite from Qixing Cave in Guizhou Province for example,a time sequence of the paleoclimatic changes was established from 43.

为了研究过去全球变化在我国高海拔低纬度地区的变化规律,在高精度、高分辨率热电离质谱铀(TIMS-U)系定年和氧同位素基本原理的基础上,以贵州都匀七星洞一石笋为例,建立了43。
