.... Sites in the northern Cobalt Embayment carry an N1 (reverse) paleomagnetic signature. They possess maximum AMS axes that trend north-northwest–south-southeast, interpreted as the direction of magma emplacement. In one area, the data rule out a cone sheet emplacement mechanism. The N3 paleomagnetic...
