Abstract
Magnetic susceptibility data from marine rocks can be used for global corre lation because of synchronous variations in global erosion. We show here co rrelations between magnetic susceptibility data from two Lower Devonian, bi ostratigraphically well defined sections, one in northwestern Spain, and on e from the Anti-Atlas region of Morocco, Using the Moroccan outcrop section , we correlate to cuttings from a Bolivian well with minimal biostratigraph ic control. Using the magnetic susceptibility data, we identify the Lower D evonian, Pragian-Emsian, and lower-upper Emsian stage boundaries in the Bol ivian well samples.
