Abstract
The Chuniespoort Group was deposited between 2460 and 2224 m.y. ago and consists
of a carbonate unit (the Malmani Subgroup, 1600-3600 m thick) conformably
overlain by a banded iron-formation unit (the Penge Iron-formation,
approximately 260 m thick). Stratigraphic profiles, measured in outcrop, were
used to subdivide the unit into formations and members and to define sedimentary
lithofacies and lithofacies cycles. The process-response model was
then applied to the lithofacies, lithofacies associations and sedimentary
cycles to determine their origin, environment of deposition and diagenetic
history...
