Palaeomagnetism and K—Ar ages of Lower Ordovician and Upper Silurian—Lower Devonian rocks from north‐west Argentina
Summary. In this paper we present palaeomagnetic data from 87 hand samples collected in a sequence of tuffs and shales (Surf Formation) of Llanvirnian age, exposed in north‐western Argentina (27° 47’ S, 68° 06’ W). After cleaning, the majority of samples showed reversed polarity and yielded a palaeo...
