概要

• 論文の詳細を見る

• Precise isotope dilution technique of Li, along with other alkalis, alkaline earths and iron, for tiny silicate materials (having as low as 10 pg Li) is described. Samples were decomposed by acids, equilibrated with mixed spikes including 6Li and directly loaded on a mass spectrometer filament without chemical separation. Li and other lithophiles were measured by successive heating procedures. Results of precise Li analyses are presented for 7 Allende chondrules, 5 bulk chondrites and three standard rocks, JB-1, JB-2, and BCR-1.
