a 1 – ODP Leg 147 (Hess Deep, East Pacific Rise), 2 – ODP Leg 153 (Kane Fracture Zone, Mid-Atlantic Ridge), 3 – ODP Leg 209 (15°20' Fracture Zone, Mid-Atlantic Ridge), 4 – ODP Leg 173 (Western Iberian margin COT, Atlantic Ocean), 5 – IODP Expedition 399 (Atlantis Massif, Mid-Atlantic Ridge). 6 – IODP Expedition 402 (Tyrrhenian Sea), this study. The location of IODP Expeditions 367-368 in the South China Sea COT is also shown (7). b Bathymetrical map and location of the Expedition 402 sites (U1614 and U1616) in the Vavilov basin (Tyrrhenian Sea). Previous drill sites and results of dredging are also shown (Sites 651, 652, 655, and 656). Colors refer to the nature of the recovered basement lithologies. White lines mark the location of interpreted normal faults.
