Abstract

Clay veins are present in deep weathering profiles in basic and ultra-basic rock beneath glacial drift at two localities on the Island of Rhum, Inverness-shire. Veins at one section are of saponite, at the other of the serpentine mineral, lizardite, with subordinate saponite. It is suggested that the veins were substantially formed during the interglacial period of development of the weathering profile, and that the lizardite formed in the lower horizons is replaced by saponite in the more intensely weathered upper horizons.
