Palaeomagnetism of Lower Ordovician and Upper Precambrian Rocks from Argentina
Palaeomagnetic data from samples collected in a rock sequence of tuffs and shales (Suri Formation), exposed in northwestern Argentina, indicate that the geomagnetic field had reversed polarity in Llanvirnian time. The samples from the top of the sequence also record, at least, an excursion of the ge...
