Figure F16. Composite magnetic stratigraphy at Site 1219 (blue line = Hole 1219A and black line = Hole 1219B). Virtual geomagnetic pole (VGP) latitudes were obtained after partial AF demagnetization of continuous measurements at a peak field of 20 mT. Polarity column shows interpreted zones of normal (black) and reversed (white) magnetization. Gray intervals indicate zones with an uncertain polarity interpretation. A. Miocene to early Oligocene, top 140 mcd. B. Early Oligocene-middle Eocene (bottom 120 mcd).
