The mean thickness of oceanic crust is 5 km whereas that of the continental is around 30 km. The continental crust is thicker in the areas of major mountain systems. It is as much as 70 km thick in the Himalayan region.

The surface of the earth can be divided into the continental crust and the oceanic crust. The continental crust is made mostly of granite while the oceanic crust is made of basalt. The average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is ...
However, this relationship remains elusive due to the lack of high-resolution velocity model of the oceanic crust and MTZ. Here, we present result from the application of full waveform inversion to wide-angle seismic data acquired over a young oceanic crust near the 9°N East Pacific Rise, ...
The results show a clear age-latitude dependence where sediment thickness increases with age of the oceanic crust, toward high southern and northern latitudes and toward the equator. In addition, we calculate the total volume of sediments in the oceans, which shows an increase of 29.7%, compared...

The evolution of global oceanic crust from Jurrassic to Present and its contribution to the global carbon budget The present day global sediment thickness (NGDC) grid will be superimposed on the revised present day oceanic age grid and used to derive a sediment thickness-age relationship. Based on...
Adakites have been initially defined as partial melts of young subducted oceanic crust under P-T conditions where garnet is stable and plagioclase is not17,18, a view subsequently widely supported1,19–22. However, alternative explanations2–4 have proposed that adakite-like rocks can be produced...
