The key point of this thesis is the strontium isotope composition and control factors of cambrian marine carbonate, upper yangtze platform, which the samples were collected from xiushan section in chongqing
論文研究重慶市秀山溶溪寒武系海相碳酸鹽的鍶同位素組成及主要控制因素。 -
This paper also discusses the strontium isotope evolution curve published over the world, present strontium isotope results of the section of cambrian in xiushan of chongqing
本文評述了國際上已有的寒武系海相碳酸鹽的鍶同位素演化曲線，公布了重慶秀山寒武系海相碳酸鹽的鍶同位素分析結果。 -
3 ) on the basis of the geochemistry methods of cathodoluminescencean, strontium isotope, carbon and oxygen isotope, trace element, inclusion, etc, pleokarst mechanism have been deeply studied. pleokarst had been brought about in the meteoric water of earths surface, and mainly in the early hercynian movement
3 ）通過陰極發光、鍶同位素、碳氧同位素、微量元素和包裹體等地球化學手段，深入地探討了巖溶作用機制，認為發生於地表或近地表大氣淡水環境，海西早期是區內巖溶作用發生的主要時期。 -
Samples for strontium isotopic screened were selected by way of the test of cathodoluminescence, observation of thin sections, and analysis of sr and mn. the mn / sr value of all samples presented in this paper are less than 2, and the cathodoluminescence is dull, however, the samples from the cambrian underwent diagenetic alteration to a certain degree, and the plotted points of the thickness and 87sr / 86sr value are somewhat discrete. the strontium isotope evolution curve drawn from the data with relatively low 87sr / 86sr value are consistent with other curves based on samples from different areas of the world, supporting the notion of global consistency of strontium isotope composition of marine carbonates
根據鋸同位素地層學的基本原理，利用已有的鋸同位素演化曲線，筆者確定重慶秀山寒武系剖面寒武系底界、下一中寒武統界線和中一上寒武統界線都應適當下移；另外嘗試確定了重慶秀山寒武紀剖面一些關鍵點的年齡，累積厚度1380m處的年齡為503 ? 509ma ，累積厚度1900m處的年齡約為500ma ，這對秀山寒武系剖面下、中寒武統和中、上寒武統界線的確定具有參考價值。 -
Over the past three years, they ' ve acquired more than 100 pounds of raw strontium isotope,
在過去的三年裡他們獲得了超過100磅的鍶原料
