Recent studies on iron meteorites. III Determination of the uranium and thorium contents
TL;DR: In this paper, a method for the isolation of radon and thorium from 10 to 100 g samples of iron meteorites was described, and the concentrations of these elements were of the order of 10 −8 g per g of meteorite.
Journal ArticleDOI
The ages of three stony meteorites and a granite
S.J. Thomson,K. I. Mayne +1 more
TL;DR: In this paper, the ages since solidification of the stone phases of three meteorites have been determined by the 40 K, 40 A method, and the ages were between 1.9 and 3.8 × 10 9 years.
Journal ArticleDOI
Coloured natural rocksalts: a study of their helium contents, colours and impurities
S.J. Thomson,G. Wardle +1 more
TL;DR: In this article, a study has been made of the quantities of helium occluded in natural, coloured rocksalts and a correlat ion found between the colour of the salts and the helium content.
Journal ArticleDOI
Recent studies on iron meteorites. V Improved methods for the isolation of uranium and thorium from meteorites
J.C. Dalton,S.J. Thomson +1 more
TL;DR: In this paper, a method for the separation of 10 −s g quantities of thorium from solutions of iron meteorites, using 1-(o-arsono-phenyl-azo)-2-naphthol-3 : 6-disulphonic acid as a precipitant and zirconium as a carrier, was described.
