Determination of the age of the earth from the isotopic composition of meteoritic lead

  • Published:
Il Nuovo Cimento (1943-1954)

Summary

Under the assumption thata) the isotopic constitution of lead at the time of the formation of the lithosphére is represented by the figures found for lead from the troilite phase of the Cafion-Diablo meteorite [Pat 53] andb) the majority of tertiary lead ores analysed for isotopic constitution has been formed according to the simple model of primary origin (equ. 3), the age of the lithospherew follows asw= 4,5 ±±0.3.109 a.

Riassunto

Nell’ipotesi chea) la costituzione isotopica del piombo all’epoca della formazione della litosfera sia rappresentata dalle cifre trovate per il piombo della troilite del meteorite del Cafion-Diablo [Pat 53] e cheb) la maggioranza dei minerali di piombo terziari di oui è stata analizzata la costituzione isotopica si sia formata secondo il semplice modello della creazione primaria (eq. 3), si deduce che l’etàw della litosfera si ottiene dalla formula (4)w = 4,5 ±0,3.109 a.
