Intraclast - A fragment of penecontemporaneous, commonly weakly consolidated, carbonate sediment that has been eroded and redeposited, generally nearby, within the same depositional sequence in which it formed (Folk, 1959 and 1962).. Lumps - In modern sediments, irregular composite aggregates of silt- or sand-sized carbonate …
The intraclastic limestones: (a) Usually is colored from whitish to creamy-white and the appearance is slightly more friable on the mineralogically analyzed samples; (b) the size of the clasts ...
Limestones are of wide variety, namely with differences in the process of formation, mineralogical composition, grain size and texture. Such variability leads to differences in weathering characteristics and behaviour under different environmental conditions and applications. Therefore, detailed studies are mandatory to assess the …
The geological background of the examined Jurassic, Cretaceous and Holocene carbonates is dealt by Morad et al. (2012), Strohmenger et al. (2006), and Lokier and Fiorini (2016), respectively.We present here a brief summary of geological settings of the studied carbonate deposits (Fig. 1).Deposition of the Jurassic (Kimmeridgian) Arab …
1 Introduction. The classification of reservoir types is a key step in carbonate reservoir research. Conventional carbonate reservoir classifications are based on the structural geneses of the carbonate rocks (Aqrawi et al., 2010; Chen et al., 2020; Jiang et al., 2015; Liu et al., 2012; Radwan et al., 2022., Shehata, 2022) and have been widely …
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 …
These intraclastic limestone facies, sometimes referred to as 'anachronistic facies' by certain authors, contain flat-pebble conglomerates, breccia, and vermicular limestone [9,10,11]. The deposition of these anachronistic facies is the manifestation of related environmental events following the LPME [ 8, 11 ].
Dolomitization is the post-depositional process by which limestone is altered into dolomite as magnesium (Mg) ions replace calcium (Ca) ions (Land, 1985). A large volume of the limestone of the Samana Suk Formation is affected by dolomites. During the Himalayan orogeny, the dolomitization took place in the region at deep burial …

In the proximal settings (Val Taleggio and Val Bracca) the Zorzino Limestone mainly consists of bio-intraclastic packstone and wackestone (bed types Cl2, Cl3, Cl4) that prevail on the intraclastic wackestone and mudstone (bed types M1 and M2). ...

Oman records in its Neoproterozoic Nafun Group (Huqf Supergroup) an essentially complete, carbonate-rich Ediacaran succession. The Nafun Group overlies the presumed Marinoan rift-related Fiq Member (ca. 635 Ma) and ends just below the Precambrian–Cambrian boundary (542 Ma).Tectonic subsidence caused by thermal …
The fastest growing export markets for Limestone of Oman between 2021 and 2022 were India ($8.33M), Bangladesh ($681k), and Kuwait ($84.7k). Imports In 2022, Oman imported $316k in Limestone, becoming the 64th largest importer of Limestone in the world. At the same year, Limestone was the 911th most imported product in Oman.
The Mesozoic succession of the Jabal Akhdar dome in the Oman Mountains hosts complex networks of fractures and veins in carbonates, which are a clear example of dynamic fracture opening and ...
The Taishaku Limestone is located around Shobara City, Hiroshima Prefecture, SW Japan (Fig. 1, Fig. 2).The limestone is divided into central and marginal facies (Hase et al., 1974) that represent a shallow-water atoll-top facies and a deeper-water resedimented carbonate slope facies, respectively.The central facies comprises …
Under a microscope, these microfacies are made up of intraclastic (10%), glauconite (5%), gastropod (2%), and other skeletal parts, as well as scattered grains of …
