Palaeomagnetism and K-Ar dating of the Carboniferous Andacollo Series (Argentina) and the age of its hydrothermal overprinting
Palaeomagnetic data from 15 hand samples collected in a sequence of tuffs of Carboniferous age (Andacollo Series) exposed in western Argentina (37°10′S, 70°38′W) are given. These samples show hydrothermal alteration. After AF and thermal cleaning the majority of samples show reversed polarity and yi...
