Short summary
Goethite is one of the most common Fe-(oxy)hydroxide minerals that is formed during hydrolyzation of rocks, implying it is a desired mineral for dating various surface and subsurface geological processes. Nowadays (U–Th) / He dating of goethite is widely used in geochronological studies. Here, in the example of goethite from the Chukchi Borderland, we introduce a new, simple methodological approach for accurate (U–Th) / He dating of goethite.
