Extrusion of subducted crust explains the emplacement of far-travelled ophiolites
Nature Communications, 2021 The interplay between continental subduction exhumation dynamics and the obduction of ophiolite sheets remains enigmatic. Here, the authors show that the extrusion of the subducted continental upper crust triggers the necking and breaking of the oceanic ...

Geological and Geochemical Controls on Subsurface Microbial Life in the Samail Ophiolite, Oman
Frontiers in Microbiology, 2017 Microbial abundance and diversity in deep subsurface environments is dependent upon the availability of energy and carbon. However, supplies of oxidants and reductants capable of sustaining life within mafic and ultramafic continental aquifers undergoing

Chrome spinel compositions as evidence for an Archaean ophiolite in the Kuhmo greenstone belt in Finland [PDF]
Bulletin of the Geological Society of Finland, 1994 Investigations into chromite compositions in Archaean ultramafic rocks are rare. Most Archaean ultramafic rocks have undergone a multi-stage history of deformation and metamorphism, and therefore fresh primary chromite is rarely preserved.
