In this work, a recent technique for the determination of the Th/U ratio in minerals and glasses was applied to relevant samples used as reference in fission-track (FT) dating. This technique, developed for estimating the ...

This study reports the nature and extent of open-system interaction between groundwater and a weathered profile developed in the high grade thorium and REE ore body in Morro do Ferro, Pocos de Caldas plateau. The radioelement ...

The U and Th distribution in K-rich acid metavolcanics affected by postmagmatic processes has been studied. Th (20 ppm) and U (2.41 ppm) average abundances are well within the normal ranges for granitic rocks, but the Th/U ...

U-series data are combined with major and trace element constraints to construct a detailed view of the magmatic system feeding the San Pedro-Linzor volcanic chain, aiding the understanding of how stratovolcanoes in extremely ...
