WebAn accretionary complex is a current (in modern use) or former accretionary wedge. Accretionary complexes are typically made up of a mix of turbidites of terrestrial material, basalts from the ocean floor, and pelagic and hemipelagic sediments. For example, most of the geological basement of Japan is made up of accretionary complexes. WebGeology is the branch of science that deals with the study of processes taking place on earth surface and in its interior as well, which gives rise to many phenomena.
