A geologic process in which the oceanic crust of the edge of a tectonic plate is thrust over the continental crust of the edge of another, adjacent plate.

[Latin obductiō, obductiōn-, act of covering or enveloping, from obductus, past participle of obdūcere, to draw forward, cover over : ob-, toward, before; see ob- + dūcere, to lead, draw; see deuk- in Indo-European roots.]

The flexure is due to a northwest obduction on the craton of the younger Pan African crust.[2] The Basin covers about forty percent of Ghana's continental landmass and stretches across six countries, viz Benin, Burkina Faso, Cote d'Ivoire, Mali, Togo and Ghana, even though the Volta River flows primarily through Burkina Faso and Ghana.
An autopsy is also referred to as post-mortem, obduction or necroscopy.

Viewed from the highway, light brown Simsima Formation overlies palaeo-hills mainly composed of black Semail ophiolite (former oceanic crust / upper mantle) and Hawasina Group sediments which were tectonically emplaced by obduction during the Campanian (Late Cretaceous).
Then it was astonishing to find out the special geology of Oman -- it is the result of something called obduction which means Oman is literally the ocean floor pushed up through plate tectonics.
During this time interval the sea-floor spreading in one and ophiolite obduction in the other area occurred (Andersen et al.
This obduction process, possibly caused by the arrival at the subduction zone of some oceanic relief (guyots chain, oceanic ridge, oceanic plateau, etc.), that was unable to enter in the subduction zone (X terrane of Mpodozis and Kay, 1990), implied exhumation and retrograde metamorphism of the rocks of the ChMC (Fig.
Following this process, eventually in upper Cretaceous and Paleocene eras simultaneous with closure of the Neotethyan Ocean, some parts of the oceanic crust have had obduction movement.
The metamorphism is related not only to overthrusting and the obduction of oceanic crust (Restrepo & Toussaint, 1976; Arias & Caballero, 1978) but also to a subduction zone setting (Sanchez, 1988).
