同位素范圍
  • isotopic : adj. 同位素的。 isotopic abundance ratio 同位素豐度比。 isotopic spin 同位旋。adv. -ally
  • range : vt 1 排列；整理（頭發等）。2 使歸類[班、行、隊]；把…分類。3 〈用被動形或反身形〉加入，站住…的一邊...
  1. According to the sr - nd isotopic characteristics of peridotite xenoliths and their host basalts, it indicates that xenoliths in hannuoba, puning area may represent source area of the host basalt because of the xenoliths and host rocks being in the same plot ; however, the xenoliths is not directly related to their host rocks of the others area for the xenoliths plot out of the range of their host basaltic rocks. thermal dynamics calculation shows that the peridotite xenoliths are formed in the condition of pressure of 9. 45 - 25kb and temperature of 945 - 1281

    橄欖巖包體及其寄主玄武巖的sr - nd同位素研究表明，漢諾壩與普寧地區部分包體樣品投點落在其寄主玄武巖nd和sr同位素的分佈范圍內，表明橄欖巖包體代表了寄主玄武巖的源區，而其它大部分地區的包體其寄主玄武巖范圍之外，表明寄主玄武巖和橄欖巖包體無成因聯系，橄欖巖包體只是偶然包體。
  2. All of the mafic samples have age - corrected moderate enriched sr and enriched nd isotopic ratios and the felsic rocks span larger range in the initial sr and nd isotopic ratios than mafic volcanics, similar to isotopic compositions of lower crust of north china block

    在sr - nd同位素組成上，中基性火山巖為中等富集的sr和低的nd同位素比值；中酸性火山巖的sr同位素比值總體較中基性巖高且變化大，類似華北陸塊下地殼巖石的同位素組成特徵。
