Nuevos datos sobre la petrología y procedencia de la Formación Miers Bluff, Isla Livingston, Islas Shetland del Sur

Abstract

The turbidites of the Miers Bluff Formation have been pelrologically analised and some compositional parameters have been calculated. The use of several ternary diagrams allow for some provenance speculations such as a source area of low metamorphic composition with progessive influence of dykes and volcanic rocks. Albitization of feldspars in part of the section poses a difficulty in a sure source area reconstruction
