6.Isotopic analyses for volcanic rocks from the two groups show wide ranges of initial strotium (0.703438~0.708329), and initial neodymium (0.512003~0.512327). Positive εNd values (+5.42 ~ +12.81) indicate that these volcanic rocks were derived from enriched mantle (EMI and/or EMII), with crustal contamination.
同位素地球化学分析揭示,斜峪关群和草滩沟群火山岩的初始Sr比值为0.703438~0.708329,初始Nd比值为0.511948~0.512327,多集中于0.512003~0.512327间,εNd均为正值(+5.42~+12.81),表明二群火山岩主要来自富集地幔源区。
