It is composed of several layers not including the overlying sediment.

Age of oceanic floor.

Sio reference series 93 30 scripps institution of oceanography. For that geologists date and study continental crust. This dataset shows the age of the ocean floor along with the labeled tectonic plates and boundaries. The hadal zone which includes the oceanic trenches lies between 6 000 11 000 metres 20 000 36 000 ft and is the deepest oceanic zone.

The following features are shown at example depths to scale though each feature has a considerable range at which it may occur. This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level. Depth below seafloor is a vertical coordinate used in geology paleontology oceanography and petrology see ocean drilling. D dutkiewicz a seton m.

Youngest red is along spreading centers. It is thinner denser younger and of different. Depth below seafloor. This dataset contains jpeg images of the oceanic age grid from muller et al.

Therefore seafloor dating isn t that useful for studying plate motions beyond the cretaceous. Age of the ocean floor a critical analysis february 4 2019 eugene ellis the ionic growing earth ige posits the same 8 elements that started the earth heated the planet for the first 3 3 5 billion years of its existence see ige fig. The data are described in a data and analysis note in the journal of geophysical research 1997 entitled digital isochrons of the world s ocean floor. Because of this correlation between age and subduction potential very little ocean floor is older than 125 million years and almost none of it is older than 200 million years.

The data is from four companion digital models of the age age uncertainty spreading rates and spreading asymmetries of the world s ocean basins. Age of oceanic lithosphere. A digital age map of the ocean floor. 2013 that can be loaded into gplates as a time dependent raster series.

The topmost layer about 500 metres 1 650 feet thick includes lavas made of basalt that is rock material consisting largely of plagioclase and pyroxene oceanic crust differs from continental crust in several ways. These age data also allow the rate of seafloor spreading to be determined and they show that rates vary from about 0 1 cm read more. Seafloor spreading is a process that occurs at mid ocean ridges where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge. Oceanic crust is about 6 km 4 miles thick.
