Thallium isotope data and major elements for Kamchatka arc lavas. Thallium isotope compositions of degassing experiments ...
Thallium (Tl) isotope ratios are an emerging tool that can be used to trace crustal recycling processes in arc lavas and ocean island basalts. Thallium is a highly volatile metal that is enriched in volcanic fumaroles, but it is unknown whether degassing of Tl from subaerial lavas has a significant...
