ABSTRACT

Five samples of diamictons from the upper slopes of Mount Kenya were studied using scanning electron microscopy. One was found to have properties consistent with origin as a lahar, but the remaining four, considered on other grounds to be glacigenic, lack diagnostic morphoscopic and fabric features of a glacial type. This may be the result of deposition in a low-energy Pleistocene glacial environment, although another factor is the advanced diagenesis which has resulted in clay enrichment and widespread cementation and coating of grains with Si and Fe.
