Figure F115. Representative vector end-point diagrams for gabbroic minicore samples from Leg 176. Alternating-field and thermal demagnetization results from adjacent minicores illustrating (A, B) minor and (C, D) more substantial southward-directed secondary magnetization component. This southward-directed secondary component occasionally is stable to AF fields as high as 50 mT (E) or may not be evident at all if the secondary magnetization is (sub)parallel to the characteristic magnetization direction (F). Solid circles are the projections of the remanent magnetization onto the horizontal plane, and open circles are the projection onto the vertical plane.
