Figure 4. Summary of interpreted lava stratigraphy, radiometric ages, and paleomagnetic data along the 63× N drilling transect compiled from this and previous studies (Duncan, Larsen, Allan, et al., 1996; Larsen and Saunders, 1998; Sinton and Duncan, 1998; Vandamme and Ali, 1998; Werner et al., 1998). Black and white coding denotes respective normal and reverse magnetized lavas. LS = Lower Series, MS = Middle Series, US = Upper Series. Expanded from Larsen and Saunders (1998).
