The White Desert, also known as the Sahara el Beyda, is a unique and otherworldly landscape located in western Egypt. The desert's landscape is characterized by its striking white rock formations that have been sculpted into various shapes by centuries of wind and sand erosion. These white rock formations, which resemble …
Over time, this erosion creates a unique topography of sinkholes, caves, underground rivers, and exposed limestone formations. In the case of Bohol Island, the karst landscape was formed over millions of years by the action of rainwater on the limestone deposits that once covered the island. As rainwater flowed over the …

Formation of Limestone Rock Formations: Various environmental factors such as water, wind, and even seismic activity further shape the limestone into different formations. In coastal areas, wave action and tidal movements often erode the limestone, creating unique features like sea cliffs, stacks, and caves. Similarly, in karst landscapes, the ...
The middle Eocene Seeb Formation represents deposition on one of the earliest "modern" style carbonate platforms, i.e., influenced by seagrasses and mangroves, and presents an opportunity to explore controls on the preservation of …
Karst is an area of land made up of limestone. Limestone, also known as chalk or calcium carbonate, is a soft rock that dissolves in water. As rainwater seeps into the rock, it slowly erodes. Karst landscapes can be worn away from the top or . dissolved from a weak point inside the rock.. Karst landscapes feature caves, underground …
The Al Aridh Formation is a tectonic unit above the Hamrat Duru Group and below the "Oman Exotics" and the Haliw Formation, respectively.

Erosion at the base of the megabreccias locally ...
We present the results of the geomorphological mapping of a region of the Dhofar (Sultanate of Oman) including two contrasting physiographic units sharing a …
Over time, all surface rocks are subject to weathering and erosion, mostly of a mechanical nature. In the case of limestone, it is the chemistry of the calcium carbonate component that plays an additional role in giving rise to the often spectacular features that are found with limestone formations. Limestone – the fizzy rock. The percentage ...
This is the first report of Cenozoic shallow marine limestone clinoforms from Oman in an outcrop of exceptional exposure. The depositional system displays a few …
The limestone formations of Tanuf valley (Natih formations of Hajar unit) are thick-bedded, massive, shallow marine limestone and clayey limestone, which have caves and springs.
Sedimentary rock - Limestone Formation, Calcium Carbonate, Fossils: Limestones originate mainly through the lithification of loose carbonate sediments. Modern carbonate sediments are generated in a variety of environments: continental, marine, and transitional, but most are marine. The present-day Bahama banks is the best known …
To the east, the Haushi limestone is absent in the Oman 3 mountains due either to erosion or non-deposition related to the rise of the Hawasina 4 Basin rift shoulder in the position of the present Oman mountains in the Early 5 Permian (Blendinger et al., 1990; Osterloff et al., 2004b).
Geological formations: Limestone rocks often contain fossilized remains of ancient marine creatures, providing valuable insights into past ecosystems. Natural wonders: The formation of stunning limestone caves and caverns, such as the Carlsbad Caverns in the United States, showcases the beauty and complexity of nature's processes.
This paper focuses on facies, sequence- and bio-stratigraphy of the Mafraq Formation type section in Wadi Sahtan, the documentation of 11 Mafraq outcrops distributed over the …
The Oman Exotic limestones blocks in the Khatm El-Shiklah (KES) area, UAE-Oman border, were deposited sometime during Middle to early Late Permian. • The KES exotic carbonates are closest in fossil assemblage and microlithofacies to the …
The Mafraq Formation, Late Triassic to Middle Jurassic Bajocian in age, was defined in well Mafraq-1 in eastern Interior Oman. The formation is 63 m thick and is composed of a siliciclastic continental unit (i.e. Lower Mafraq), overlain by a mixed siliciclastic-carbonate lithology reflecting the onset of the Jurassic marine transgression …
is referred to as a part of the Seeb Limestone Formation and Pabdeh Marl Formation (Jones and Racey 1994; p. 292-293). It is widely exposed throughout large areas of southern Iraq, Kuwait, Saudi Arabia, Qatar, UAE and Oman (Jones and Racey 1994). The Dammam Formation consists of a sequence of shal-low water shelf carbonates …
It also is a weathering and erosion agent, producing the grains that become detrital sedimentary rock. Several special properties make water an especially unique substance, and integral to the production of sediments and sedimentary rock. 5.2: Weathering and Erosion Bedrock refers to the solid crystalline rock that makes up the Earth's outer ...
The upper part of the Qahlah Formation is predominantly mudstone with a thickness of about 15 to 20 m before being overlain by the 'Simsima' Formation (Fig. 1C). In the eastern Oman Mountains, the Qahlah Formation is distinguished through its clast nature composition sourced by the erosion of the substrata (Fig. 1B and C). …
Dhera and Dibba Limestone Formations. The Dhera Limestone Formation (Figs. 4.2 and 4.10; Table 4.3) crops in both the Dibba and Hatta zones of the UAE, and Jebal Sumeini and Dehra areas of northern Oman, where it comprises a heterogeneously deformed (folded, thrusted), well-bedded, variably silicified turbiditic calcarenites and …
At the UAE and the Sultanate of Oman border, the Late Cretaceous Simsima Formation is subdivided into two prominent members: the lower member is orbitoidal limestone with a rich rudist fauna, while the upper member is well-bedded, highly fossiliferous limestone (Alsharhan et al. 2000).In Oman, rudist-bearing bioclastic …

Clints and grykes – rainwater flowing over an impermeable surface will, on reaching (permeable) limestone, be able to dissolve the joints into grooves called grykes, leaving blocks or clumps of limestone in between called clints. You can see a video featuring these formations on the Malham page. Limestone pavements – exposed clints and ...
Limestone Formation By Water Evaporating Environment. Some limestones are formed through evaporation in caves where water seeps/pours through the cave floor. Upon evaporation, calcium carbonate dissolved in water gets deposited throughout the cave ceiling and wall. ... Erosion is the process of constant disintegration of rocks and …

Erosion is a mechanical process, usually driven by water, gravity, (see Chapter 10), wind, or ice (see Chapter 14) that removes sediment from the place of weathering. Liquid water is the main agent of erosion. Figure (PageIndex{1}): Grand Canyon from Mather Point. Erosion resistance is important in the creation of distinctive geological ...
