2013: First description of a metamorphic sole related to ophiolite obduction in the northern Caribbean: Geochemistry and petrology of the Güira de Jauco amphibolite complex (eastern Cuba) and tectonic implications

First description of a metamorphic sole related to ophiolite obduction in the northern Caribbean: Geochemistry and petrology of the Güira de Jauco amphibolite complex (eastern Cuba) and tectonic implications Abstract The Güira de Jauco Amphibolite Complex underlies the Mayarí–Baracoa Ophiolitic Belt (eastern Cuba) and is composed of highly foliated amphibolite, locally with blocks of sheared…

2013: Late Cretaceous subduction of the continental basement of the Maya block (Rabinal granite, central Guatemala): Tectonic implications for the geodynamic evolution of Central America

Late Cretaceous subduction of the continental basement of the Maya block (Rabinal granite, central Guatemala): Tectonic implications for the geodynamic evolution of Central America Abstract The Rabinal Granite is a peraluminous S–type composite pluton formed upon partial melting of a metasedimentary source region that fringes the southernmost North America plate in central Guatemala. It is…

2013: “Garnierite” ore and Ni-serpentine mineralizations from the Falcondo Ni-laterite deposit (Dominican Republic): an approach from quantitative XR element imaging

"Garnierite" ore and Ni-serpentine mineralizations from the Falcondo Ni-laterite deposit (Dominican Republic): an approach from quantitative XR element imaging Abstract ”Garnierites” and Ni-serpentines are the main Ni ores in hydrous silicate-type Ni-laterites. In the Falcondo Ni-laterite, “garnierites” are found within the saprolite horizon mainly as fracture-fillings and thin coatings on joints. Different greenish colours are…

2012: Hydrothermal origin and age of jadeitites from Sierra del Convento Mélange (Eastern Cuba)

Hydrothermal origin and age of jadeitites from Sierra del Convento Mélange (Eastern Cuba) Abstract Jadeitite (jadeite jade) from Sierra del Convento (eastern Cuba) occurs in a subduction-related serpentinite-matrix mélange associated with a variety of high-pressure tectonic blocks including garnet-amphibolites and related anatectic trondhjemites. The eastern Cuban jadeitite is massive and characterized by rare quartz inclusions…

2011: Petrogenesis of fertile mantle peridotites from the Monte del Estado massif (southwest Puerto Rico): a preserved section of proto-caribbean lithospheric mantle?

Petrogenesis of fertile mantle peridotites from the Monte del Estado massif (southwest Puerto Rico): a preserved section of proto-caribbean lithospheric mantle? Abstract The Monte del Estado massif is the largest and northernmost serpentinized peridotite belt in southwest Puerto Rico. It is mainly composed of spinel lherzolite and minor harzburgite with variable clinopyroxene modal abundances. Mineral…

2011: Timing and Evolution of Cretaceous Island Arc Magmatism in Central Cuba: Implications for the History of Arc Systems in the Northwestern Caribbean

Timing and Evolution of Cretaceous Island Arc Magmatism in Central Cuba: Implications for the History of Arc Systems in the Northwestern Caribbean Abstract SHRIMP and conventional zircon dating place temporal constraints on the evolution of the Cretaceous Volcanic Arc system in central Cuba. The arc has a consistent stratigraphy across strike, with the oldest and…

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…
