INTERBASALT IC CLAYS FROM THE FAEROE ISLANDS, NORTHEASTERN ATLANTIC
A B STR ACT: Mineralogical nd chemical examination of Tertiary interbasaltic clays from the Faeroe Islands revealed three types of alteration of volcanic tufts and basalts: (1) Argillization of volcanic tufts within a lacustrine nvironment resulted in the formation of aluminous beidellites and metah...
