2016: The geology of Cuba: A brief overview and synthesis

The geology of Cuba: A brief overview and synthesis Abstract Cuba is the largest island in the Greater Antilles, and its geology records three important episodes: (1) the Jurassic breakup of North and South America (Pangea) and associated passive margin and oceanic sedimentary and magmatic evolution; (2) the sedimentary, magmatic, and metamorphic evolution of an…

2016: Twenty-five million years of subduction-accretion-exhumation during the Late Cretaceous-Tertiary in the northwestern Caribbean: The Trinidad Dome, Escambray Complex, Central Cuba

Twenty-five million years of subduction-accretion-exhumation during the Late Cretaceous-Tertiary in the northwestern Caribbean: The Trinidad Dome, Escambray Complex, Central Cuba Abstract The Trinidad dome, Escambray complex, Central Cuba, forms part of an accretionary wedge built-up during intra-oceanic subduction in the Caribbean from the Late Cretaceous (∼75 Ma) to Tertiary. Fieldwork, microscopic studies, P-T estimates and…

2016: Petrogenesis and 40Ar/39Ar dating of proto-forearc crust in the Early Cretaceous Caribbean arc: The La Tinta mélange (eastern Cuba) and its easterly correlation in Hispaniola

Petrogenesis and 40Ar/39Ar dating of proto-forearc crust in the Early Cretaceous Caribbean arc: The La Tinta mélange (eastern Cuba) and its easterly correlation in Hispaniola Abstract The La Tinta mélange is a small but singular ultramafic mélange sheet that crops out in eastern Cuba. It is composed of dolerite-derived amphibolite blocks embedded in a serpentinite…

2016: Geochemical record of subduction initiation in the sub-arc mantle: insights from Loma Caribe peridotite (Dominican Republic)

Geochemical record of subduction initiation in the sub-arc mantle: Insights from the Loma Caribe peridotite (Dominican Republic) Abstract The Loma Caribe peridotite body is mainly composed of serpentinized spinel harzburgites and lherzolites and minor orthopyroxene-bearing dunites and dunites. Modal proportions, mineral and whole-rock major and trace element compositions generally coincide with those of abyssal mantle…
