Stratigraphy
Formation: | Lower Bauxite |
Stratigraphic resolution: | bed |
Lithology and environment
Primary lithology: | lenticular,brown,red silty conglomerate |
Secondary lithology: | planar lamination,red,yellow claystone |
Includes fossils? | Y |
Lithology description: "[lens is] 3 m of red-brown boehmitic bauxite, consisting of alternating 300 mm thick beds of structureless mud-grade bauxite and 40-100 mm thick arenitic or arenitic/ruditic units...the bauxite is capped by 0.5 m of laminated kaolinitic clay of mottled yellow and red colour, and this is topped...by limestone. The bones occurred in greatest concentration in a 0.6 m thick band in the middle of the lens...virtually a bone-supported conglomerate...the bones were found in the mud-grade bauxites in the lower 1 m of the section." | |
Environment: | karst indet. |
Glacial or sequence phase: | transgressive |
Geology comments: "an extensive karst surface, formed after uplift of the unlderlying limestones, providing clear evidence of subaerial erosion and tropical conditions of soil development. The bauxite occupied karst depressions to a depth of several metres, often filling caves and fissures." |
