Bending-related faulting and mantle serpentinization at the Middle America trench

Ranero, C. R.; Morgan, J. Phipps; McIntosh, K.; Reichert, C. (Nature, 2003-09-25)

The dehydration of subducting oceanic crust and upper mantle has been inferred both to promote the partial melting leading to arc magmatism and to induce intraslab intermediate-depth earthquakes, at depths of 50–300 km. ...
Element fluxes from the volcanic front of Nicaragua and Costa Rica

Carr, Michael J.; Saginor, Ian; Alvarado, Guillermo E.; Bolge, Louise L.; Lindsay, Fara N.; Milidakis, Kathy; Turrin, Brent D.; Feigenson, Mark D.; Swisher III, Carl C. (Geochemistry, Geophysics, Geosystems, 2007-06-02)

Geochronologic and geological data define a 600 ka age for the current volcanic front in Costa Rica. In Nicaragua, this age is less constrained but is likely within the range 600 ka to 330 ka. In Costa Rica, the new ...
Evidence for middle Cretaceous accretion at Santa Elena Peninsula (Santa Rosa Accretionary Complex), Costa Rica

Baumgartner, P. O.; Denyer, P. (Geologica Acta, 2006)

An oceanic assemblage of alkaline basalts, radiolarites and polymictic breccias forms the tectonic substratum of the Santa Elena Nappe, which is constituted by extensive outcrops of ultramafic and mafic rocks of the Santa ...
