The sedimentology and uranium mineralization of the Beaufort Group in the Beaufort-West - Fraserburg - Merweville Area, Cape Province

The sediments of the lower part of the Beaufort Group
(Permian) consist of mudstones, siltstones, fine- to very
Fine-grained sandstones and small amounts of intraformational
conglomerate. The mudstones are generally a
brownish-purple colour, and are massive. The siltstones
are generally greyish-green coloured, and are sometimes
ripple cross-laminated. The sandstones vary in colour
from green to grey. horizontally-bedded, trough cross bedded
and ripple cross-laminated sandstone subfacies
were recognized. All the sandstones found in the area
studied may be described as fine- to very fine-grained,
moderately sorted, arkosic wackes.
The stratigraphic interval studied was found to have a
Thickness of about 850 m. No readily mappable subdivisions
were found. The sandstone to stltstone and mudstone ratio
for the stratigraphic interval is about 1:4.
