摘要: Abstract Quantitative spectrochemical determinations of Li, Sc, Sr, Ba and Zr in 21 specimens chondrite, 7 other silicate meteorites 13 ultramafic rocks are presented discussed. Abundances chondrites have been determined as: Li (2.7 ppm), Sc (6 Sr (11 (8 ppm) (33 ppm). Each element shows a high degree uniformity abundance; distribution is possibly lognormal. β-activity Rb87 calculated to generate ~13% total Sr87 chondrites.
