Notes
Breakaway with outcrops of Tregolana shales/sandstones, highly weathered, kaolinised. Overlain by 1.5-2 m of greenish-grey, medium-grained, well-sorted sandstone (Tertiary?) which is mainly structureless but at one spot with faint lamination. Grades upwards into silcretised sandstone or silcrete with laminar and nodular pedogenetic textures. Here angular unconformity between Neoproterozoic sediments and Tertiary(?) sandstone/silcrete due to flexure/monoclinal structure in shales. Dip on flexure 335/25 & 310/35. P: 6568-79.
