isotope value
解釋
同位素值-
In terms of sulphur isotope result from sphalerite, galenite > pyrite and chalcopyrite, the 8 34s % o value obtained in fozichong orefield ranges mainly between 0 ~ + 5, which is coincident with the average 5 34s % o value of submarine stratabound sulphide deposits in silurian strate distributed over other areas of the world
地球化學研究顯示，佛子沖礦田硫同位素5倫值主要集中分佈在0 5之間，與世界其它地區志留系海相硫化物礦床的6噸陸值大體一致。 -
In this dissertation we research the inversion pattern of three water through environment isotope information analysis, evaporation pattern analysis and inversion analysis of groundwater ; quantitatively analyse inversion amount through rule computational method and numeric value imitation, supplying scientific foundation for evaluation of water resources and rightful development and use
論文通過環境同位素信息分析、潛水蒸發試驗分析、近河岸地帶地下水動態分析研究三水轉化規律特徵；採用常規計算方法和數值模擬方法，定量分析地下水各轉化資源量。為研究區水資源評價及合理開發利用提供了科學依據。 -
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。 -
The application value of traditional method to explore the oil and gas source using carbon isotope was bounded by the type and maturity of source rock
摘要利用氣體碳同位素探索油氣來源的傳統方法由於受源巖類型、源巖成熟度等因素的影響，其實際應用受到很大的限制。
