Clay fraction carries valuable geochemical information from mobile elements, where it can help find geochemical anomalies, such as for U

In order to extract the -2 micron fraction from the rest of the soil/rock samples, Actlabs has developed a procedure to isolate the clay fraction fit for exploration project purposes. The method includes suspension of the clays, followed by extraction of the clays in a clean lab environment; subsequently the extracted clays are analyzed for the trace elements and/or indicative features such as stable isotopes
