Abstract:
Two components of magnetization were isolated in the Silurian-Devonian Andreas redbeds of the central Appalachians of Pennsylvania (lat 40.75 degrees N, long 75.78 degrees W): a thermally distributed, synfolding B component, and a thermally discrete, pre-Alleghenian-age folding C component. The C component mean direction and associated pole position correspond to a Silurian-Devonian paleolatitude for the Andreas location of about 35 degrees S, which, in conjunction with Early Devonian results from Gondwana, is consistent with an Early Devonian supercontinent configuration.
