KEYWORDS: Clay mineral types, kaolinite, illite, Mfamosing.

ABSTRACT:

Bulk clay mineralogical analyses were carried out on samples from the Mfamosing Limestone deposit. Results indicate the presence of Kaolinite (57%), illite (33%), Smectite (4%) and mixed layer clay types (10%). Kaolinite and smectite are restricted to the southern part of the study area, while illite occurs dominantly in the north. Mixed layer clays show no discernable trend. Factors identified to account for the occurrence of these clay types and their distribution include: the adjoining Oban Massif, the physiography of the area and climate. The clay mineral assemblages allowed for the evaluation of depositional paleoenvironrnent of the limestone unit.
