TīmeklisIf it is simply a ratio then dividing the concentration of the one by the other would suffice. the ratios would be in percentage, ppm or moles of each. the latter is normally applicable when... TīmeklisThe long-term measurement reproducibility of δ 94 Zr is generally better than ±0.06‰ (uncertainty represented by two standard deviations, hereinafter referred to as 2 SD), … Tīmeklis2024. gada 5. jūl. · Zirconium and Hf are nearly identical geochemically, and therefore most of the crust maintains near-chondritic Zr/Hf ratios of ∼35–40. By contrast, many high-silica rhyolites and granites have anomalously low Zr/Hf (15–30). As zircon is the primary reservoir for both Zr and Hf and preferentially incorporates Zr, crystallization … rdr2 save sean
