Results suggest that partial melting and fluid interaction are two efficient mechanisms that encourage Cu migration in the lower crust. Keywords: Cu isotope of lower continental crust, Cu mobilization, Metasomatism, Fluid interaction, Partial melting 1. Introduction Cu is a chalcophile element that...
A process for changing the ratio of isotopes of an element contained in the cation of a salt which comprises contacting a solution containing such a salt with extensive surfaces of a zeolitic material having a selective affinity for an isotope of the element separating the solution from the ...
