Resumen: | In: Hermelín A., Michel, ed. Memorias. Medellín, Antioquia. Universidad EAFIT, jul. 1992. v.1. v.1. Presentado en: Simposio Latinoamericano de Riesgo Geológico Urbano, 2; Conferencia Colombiana de Geología Ambiental, 2; Pereira, 15-18 jul. 1992. Several groups of volcanic ash layers found in the Department od Risaralda can be differenciated on the basisof their heavy mineral content. In post-gracial ashes, pyroxenes show a generally well defined predominance over amphiboles. Furthermore, sectors distributed concentrically around the Ruíz-Tolima show systematic variations in the ashes mineralogical propertied. Changes in granulometry and humidity were also observed in the profiles (AU). / RISARALDA |
