What is Caribbean Lithosphere (CALOR) research group?
CALOR is an international research group whose investigation focuses on a multidisciplinary approach to the understanding of the processes and environments in which (paleo-) subduction zones of the caribbean plate form. More precisely we investigate the magmatic, metamorphic and ore-deposit records of (paleo-) subduction zones of Cuba, Dominican Republic and Central Cordillera of Colombia.
They are key regions for the understanding of Caribbean-North America and -South America plate interactions. The geological development of the Caribbean region is largely controlled by a number of subduction zones that formed along its margins from the break-up of Pangea during the Jurassic until Present.
Research themes associated with the group include:
- Origin and evolution of Caribbean ophiolites
- Petrogenesis of Caribbean ophiolitic chromitites
- Origin and evolution of Caribbean Cretaceous volcanic arc
- Petrogenesis of serpentinite-matrix and -blocks from the Antillean subduction channel
- Mineral deposits of the Greater Antilles and their plate tectonic settings of formation
2017: Discovery of Ni-smectite-rich saprolite at Loma Ortega, Falcondo mining district (Dominican Republic): geochemistry and mineralogy of an unusual case of “hybrid hydrous Mg silicate – clay silicate” type Ni-lateriteDiscovery of Ni-smectite-rich saprolite at Loma Ortega, Falcondo mining district (Dominican Republic): geochemistry and mineralogy of an unusual case of “hybrid hydrous Mg silicate – clay silicate” type Ni-laterite Abstract Hydrous Mg silicate-type Ni-laterite deposits, like those in the Falcondo district, Dominican Republic, are dominated by Ni-enriched serpentine and garnierite. Recently, abundant Ni-smectite in the saprolite zone have been discovered Continue ReadingRead more
