Abstract
Samples collected from folded carbonate rocks of the Early Permian Copacabana Group exposed in the Peruvian Subandean
Zone have been subjected to detailed palaeomagnetic analysis.
Thermal demagnetisation of most samples yield stable high
unblocking temperature directions dominantly carried by titanomagnetite minerals.
This remanence, identified in 32 samples (43
specimens), is exclusively of reverse polarity consistent with the Permian–Carbonif
Less
