Abstract

Lesser Himalayan granites show various stages of weathering. Primary cracks, grain boundaries and joints have initiated and controlled the weathering processes and resulted in the decomposition of the granites. Feldspars and mica act as key minerals for the initiation of weathering. Later stages of weathering are dominated by the varying nature of weathered clay.

Etude de l’alteration de granites de l’Himalaya dans l’Ouest de I’inde

Résumé

Les granites étudiés présentent différents stades d’altération. Les fissures primaires, les limites de grains et les joints sont les facteurs à l’origine de la déciomposition de ces granites. Les feldspaths et les micas sont les minéraux clefs à l’origine de cette altération. Les stades plus avancés de cette altération sont caractérisés par différentes espèces d’argiles.
