Chrysotile on serpentinitic rocks in La Bélgica mine, Córdoba Province

La Bélgica mine is located on the eastern flank of the sierra de Comechingones, in the department of Calamuchita (Córdoba province). It is emplaced in a serpentinitic body of the western ultamafic belt of the Sierras Pampeanas de Córdoba. In this work, the serpentinitic rocks of La Bélgica mine were...

Argentine Asbesto Serpentine La Bélgica mine is located on the eastern flank of the sierra de Comechingones, in the department of Calamuchita (Córdoba province). It is emplaced in a serpentinitic body of the western ultamafic belt of the Sierras Pampeanas de Córdoba. In this work, the serpentinitic rocks of La Bélgica mine were studied, with special emphasis on chrysotile, the only asbestiform polymorph of the serpentine group. Chrysotile is developed in veinlets within the serpentine rock, in fractures and shear zones. The habit is fibrous and the crystals grow perpendicularly to the walls of the fracture (cross-fiber asbestos). Samples from the veins and the serpentinite were taken and studied by optical microscopy, X-ray diffraction, chemical analysis, SEM-EDS and thermal analysis TG-DTA. On thin sections, cross and slip fibers as well as asbestiform veinlets show a variable crystalline growth. Frequently, cuts and replacements between these veinlets and fiber microstructures indicate that they were formed at several stages of mineralization. © 2015, Asociacion Geologica Argentina.
