Stable isotope compositions of pedogenic clay minerals can be used as a paleoclimatic proxy. The underlying fundamental assumption is that pedogenic clays are formed in isotope equilibrium with the environment, which is well-documented for hot and hu

Abstract The amalgamation of Laurentia was initiated along the western margin of the Rae craton. However, the tectonic setting that generated magmatic rocks along this margin has long been debated, with the Thelon tectonic zone in the north having fo

Abstract Tectonic mélanges, characterized by conditions reflective of modern subduction fault zones, preserve mineral veins formed through mass transfer, a mechanism influencing the slip behavior of subduction megathrusts. In this study, we apply se
