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…
