Objective: Since their identification in the early 90's, extension along oceanic detachment faults has been recognized as a fundamentally distinct mode of seafloor spreading that does not result in a classical Penrose model of oceanic crustal structure. This type of spreading is characterized by: formation of oceanic core complexes; tectonized and heterogeneous lithosphere; extensive exposure of gabbro and serpentinized mantle at the seafloor; some of the largest hydrogen-rich, deep-sea hydrothermal systems and mineral deposits; and large diversity in the deep-sea and subsurface biosphere.
The plan for this WG is to:
a) Foster and strengthen links to other efforts and programs towards the study of oceanic detachment faults;
b) Animate and facilitate coordination within the scientific community to advance the understanding of these structures.

the 2013 activities of the Oceanic Detachments InterRidge Working Group.
(1) Convening a topical session at the 2013 AGU Fall Meeting;
The InterRidge Oceanic Detachments WG was put in place in January 2012, following the results and recommendations of the 2010 AGU Chapman Conference on “Detachments in the Oceanic Lithosphere”: (ht

After the initial establishment of the Working Group (WG), membership to the WG will remain open to the international scientific community while the WG is active. New members interested in the WG theme will be expected to promote and contribute intellectually to the activities of the WG, and with ideas/suggestions that help carry on the mandate of the WG.
