| Notes |
Additional information (en): This rectangle-shaped feature, located in the extinct Parece Vela Basin in thePhilippine Sea, is by far the largest known OCC on Earth. It is an elongated massif with a distinct corrugated surface consisting of several individual domal highs. Most of the topographic elements of this feature are ridges and rises. Minimum depth (m): 2376. Maximum depth (m): 6755. Total relief (m): 4379. Dimension/size: 130 km × 182 km. |

GEBCO: discoverer and year of discovery (en): Discoverer: Japanese survey vessel "Takuyo". Year of discovery: 1985. History: Named from the world-famous Japanese film character, Godzilla, and the Oceanic Core Complexes (OCCs), or megamullions, which cover this area. OCCs are domal bathymetric highs characterized by axis-normal surface corrugations and exposures of serpentinized peridotite and gabbroic rocks which are interpreted as exhumed footwalls of low-angle detachment faults. They provide a valuable opportunity to directly study the architecture of oceanic lithosphere, together with the tectono-magmatic processes associated with its formation and evolution, at oceanic spreading centers. |
