Chemical, Petrographic and Spectral Characterization of the Dominican Republic´s Garnierita

Garnierite is a hydrated silicate of magnesium and nickel, which is associated with deposits in the weathering zone of serpentinized ultramaphic rocks. In this work, analytical data (petrographic studies, X-R Fluorescence (XRF), X-Ray Diffraction (XRD) and spectroradiometry) are presented from a rep...

In this work, analytical data (petrographic studies, X-R Fluorescence (XRF), X-Ray Diffraction (XRD) and spectroradiometry) are presented from a representative sample. The sample belongs to the serpentinized peridotites of Loma Caribe formation, in the central part of the Dominican Republic. Petrographically, sepiolite-falcondoite and chalcedony are identified.

La garnierita es un silicato hidratado de magnesio y níquel, que se encuentra asociado a depósitos en la zona de intemperismo de rocas ultramáficas serpentinizadas. En el presente trabajo se presentan datos analíticos de una muestra a la que se le realizaron estudios petrográficos, Fluorescencia de Rayos X (FRX), Difracción de Rayos X (DRX) y espectrorradiometría. La muestra pertenece a las peridotitas serpentinizadas de la formación Loma Caribe, en la parte central de República Dominicana. Petrográficamente, se identifica sepiolita-falcondita y calcedonia. Los análisis de FRX muestran altos valores de Ni, Cu, Fe. Para la DRX se determina garnierita y cuarzo asociado. Espectrorradiometricamente, se obtienen minerales de stevensita, saponita, muscovita, glaucofana e illita magnésica. Con esta muestra también fue posible demostrar y presentar por primera vez la firma espectral que identifica el mineral garnierita de República Dominicana brindando nueva y más actualizada información sobre este mineral.
