2011: Subduction of young oceanic plates: a numerical study with application to aborted thermal-chemical plumes

Subduction of young oceanic plates: a numerical study with application to aborted thermal-chemical plumes Abstract We investigated numerical models of initiation and subsequent evolution of subduction of young (10–30 Myr) oceanic lithosphere. Systematic numerical experiments were carried out by varying the age of the subducting plate (10, 12.5, 15, 17.5, 20, 25 and 30 Myr),…

2011: Timing of subduction and exhumation in a subduction channel: Evidence from slab melts from La Corea mélange (eastern Cuba)

Timing of subduction and exhumation in a subduction channel: Evidence from slab melts from La Corea mélange (eastern Cuba) Abstract High pressure igneous rocks (tonalites), generated by partial melting of subducted basaltic rocks accreted to the mantle wedge, are present in the La Corea serpentinite-matrix mélange (eastern Cuba) as centimeter- to meter-sized blocks and as…

2011: Serpentinites and serpentinites within a fossil subdution channel: La Corea melange, eastern Cuba.

Serpentinites and serpentinites within a fossil subdution channel: La Corea melange, eastern Cuba. Abstract A variety of metaultramafic (serpentinite) rocks in La Corea mélange, Sierra de Cristal, eastern Cuba, show differences in chemical, textural and mineralogical characteristics demonstrating a variety of protoliths. The mélange originated during the Cretaceous as part of the subduction channel associated…
