Abundances of K, Rb, Sr and Sr isotopes in ultramafic rocks and minerals from western North Carolina
TLDR
In this paper, a detailed study of the strontium isotopic composition of closely associated alpine-type ultramafic intrusions in western North Carolina has revealed variable but high 87 Sr 86 Sr ratios, similar to those found in previous reconnaissance studies.About:

Petrogenetic implications of some new geochemical data on eclogitic and ultrabasic inclusions
TL;DR: Some eclogitic and ultrabasic inclusions, their separated minerals, host rocks, and related samples have been analyzed by mass-spectrometric isotope dilution for K, Rb, Sr, Ba and rare-earth elements (RE), and by other techniques for selected major elements as discussed by the authors.
