Figure F1. Location map for Leg 198 sites on the Shatsky Rise. The rise is ~1500 km long and 500 km wide. The rise comprises three prominent highs (Southern, Central, and Northern), all of which were tested during Leg 198. Sites 1207, 1213, and 1214 are the focus of this study in that they contained early Aptian organic-rich shales and tuffaceous sedimentary rocks. Perspective is viewed from the south looking north.
