C -calcarenite
-general sequence W to E is siltstone, quartz, calcarenite gradually enriching in alumina through shaley siltstone (muscovite blastic) into a 30 m section rich in calcareous sandstone and calcsilicate, then into muscovite blastic feldspathic sandstone with rare channel deposits of conglomerate (granite pebble dominant) then into festoon bedded sands with interbeds of shaley sandstone
