It is one of the famous and attractive geological sites in Egypt and deserves to be one of the protectorate areas. The Actaeonella-bearing limestone-marl member of Abu Roash formation in El-Hassana dome exhibits a contrasting dark tone relative to the encompassing white cliff forming limestone-dominated members. It consists of shale, marl and limestone that yield in some places Trochactaeon salomonis, Nerinea requieniana, Durania arnaudi and Millestroma nicholsoni. Facies hierarchy at El-Hassana includes: low-energy skeletal floatstone representing initial and start-up stage, rudist\/ sponge boundstone of the catch-up and colonization stage, and high-energy bioclastic grainstone representing a cease of mound growth and destructive stage via effective wave and current action. The abrupt development of middle to outer platform argillaceous carbonate facies with local rudist\/ sponge mounds of the Actaeonella-bearing limestone member above the inner platform shallower carbonate facies of the underlying ¿limestone¿ member may suggest a retrogradation accompanied with a deepening of the depositional accommodation.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783659814310\"\u003e\u003ch3\u003eGrowth of Cretaceous Tethys Realm Population, Facies Hierarchy, Depositional Model\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783659814310","offer_id":39822384660573,"sku":"9783659814310","price":23.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/884e52f3-12e3-4b62-bab7-2dfd5a8c799f.jpg?v=1773208399","url":"https:\/\/shop.autorenwelt.de\/products\/rudist-coralline-sponge-gastropod-in-el-hassana-protectorate-egypt-von-hanan-s-badawy","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
