This short manuscript presents a detailed investigation into the metamorphic evolution of a unique corundum-bearing chloritite from the layered metagabbro body within the Etirol-Levaz continental slice in Valtournenche, Aosta, Italy. This sample represents the first occurrence of corundum and högbomite-bearing mafic rocks in the Western Italian Alps. The data presented here mostly summarizes the content of the article Regis et al. (submitted to European Journal of Mineralogy).
