A. Essalhi et al., TEXTURAL, MINERALOGICAL AND GEOCHEMICAL E VIDENCE FOR A METASOMATIC ORIGIN OF ALBITIES FROM THE WESTERN HIGH ATLAS (MOROCCO), Comptes rendus de l'Academie des sciences. Serie 2, Mecanique, physique, chimie, sciences de l'univers, sciences de la terre, 316(8), 1993, pp. 1083-1090
Textural, mineralogical and geochemical evidence indicates a metosomat
ic origin for the studied albitites, with gains of Na and Ca and losse
s of Fe, K and Mg. A large variety of volcanic and volcano-sedimentary
protoliths is demonstrated.
