About: Tamala Limestone

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Tamala Limestone is the geological name given to the widely occurring eolianite limestone deposits on the western coastline of Western Australia, between Shark Bay in the north and nearly to Albany in the south. The rock consists of calcarenite wind-blown shell fragments and quartz sand which accumulated as coastal sand dunes during the middle and late Pleistocene and early Holocene eras. As a result of a process of sedimentation and water percolating through the shelly sands, the mixture later lithified when the lime content dissolved to cement the grains together.

  • Tamala Limestone is the geological name given to the widely occurring eolianite limestone deposits on the western coastline of Western Australia, between Shark Bay in the north and nearly to Albany in the south. The rock consists of calcarenite wind-blown shell fragments and quartz sand which accumulated as coastal sand dunes during the middle and late Pleistocene and early Holocene eras. As a result of a process of sedimentation and water percolating through the shelly sands, the mixture later lithified when the lime content dissolved to cement the grains together. Exposed limestone formations at The Pinnacles Desert near Cervantes clearly show the limestone formation through the sedimentary process. At its thickest, the Tamala Limestone comprises the massive Zuytdorp Cliffs, up to 250 m high, extending for 150 km between Kalbarri, Western Australia and south of Steep Point. (en)
