ANALYSIS OF ITARARè SUBGROUP CLAYS EXPOSED IN WITMARSUM, PARANA STATE, BRAZIL
The objective of this project is to determine the depositional environment and origin of the clay units. Additionally, analysis will determine if this is a single unit or multiple facies within the Itararè. In the field, clay units were described and stratigraphic sections were measured. In the laboratory, chemical analysis using XRD and pollen analysis will determine the age and depositional environment (marine or lacustrine conditions). Results will aid in the reconstruction of glacial conditions and determination of the number of glacial advances and retreats in the Witmarsum area.
Research for this study was funded by a grant from the N.S.F.-R.E.U Program (NSF-EAR-1262945).
