Limestone formation.

The Martin Formation in southern Arizona contains limestone, sandstone, shale and chert deposited in the Late Devonian and laden with fish and invertebrate fossils. A lull between orogenies in the Mississippian period of the Carboniferous resulted in a major marine transgression and the formation of thick limestone. Oolite. Oolite is a sedimentary rock made up of ooids (ooliths) that are cemented together. Most oolites are limestones — ooids are made of calcium carbonate (minerals aragonite or calcite ). Ooids are spheroidal grains with a nucleus and mineral cortex accreted around it which increases in sphericity with distance from the nucleus. This weathered hollow limestone formation is one of the most evocative and intimate of the coastal formations of the Great Ocean Road. Part-blowhole, part-archway, part-cave, its serene rock pools and smooth boulders frame the sea views and offer a sometimes peaceful place to soak in the wonders of sea-spray and nature. Enjoy stunning coastal ...Two of the most widely used classifications are those of Folk (1959,1962) and Dunham (1962). Both classifications subdivide limestone s primarily on the basis of matrix content. Most limestone s are classified by Folk allochemical Rock s if they contain over l0% allochems (transported carbonate grains). Based on the percentage of interstitial ...
