The sedimentary thickness of the Cudappa basin is of the order of 12 km (7.5 mi) with volcanic sequences in the form of sills and dykes. A prominent Eparchaean Unconformity of the formation resting on the Archaean peninsular gneissic complex is noted. Rocks of Cuddapah Supergroup including Kurnool Group are the prominent feature of the basin. [15]
Uluru (Ayers Rock) is a large sandstone formation in Northern Territory, Australia.. Sedimentary rocks can be subdivided into four groups based on the processes responsible for their formation: clastic sedimentary rocks, biochemical (biogenic) sedimentary rocks, chemical sedimentary rocks, and a fourth category for "other" sedimentary rocks formed by impacts, volcanism, and other minor processes.
