Lime mudstone
The reservoir characterization of Lower Qamchuqa (Shu'aiba) Formation (Aptian) is studied at the well BH-86 of Bai- Hassan Oilfield in Kirkuk area, Northern Iraq. The lithological study (of 91 thin sections) revealed that the formation consists of shaly limestone, a thin bed of marl within the limestone, and dolomitic limestone.Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate Mudstone is a fine-grained, dark gray sedimentary rock, which is formed from silt and clay and is similar to shale but has less laminations 1.2 History 1.2.1 Origin New Zealand Unknown 1.2.2 Discoverer Belsazar HacquetAug 1, 2022 · Therein, the mudrock successions composed of meter-scale mudstone–limestone couplets are the most important shale oil-producing layers. The controls on the deposition of the meter-scale mudstone–limestone couplets, however, remain enigmatic, constraining the analysis of lithofacies and, therefore, sweet spot distributions.

2.4 Definition of shale/mudstone/mudrock. Shale (or mudstone, mudrock) is the most widely used class name for all fine-grained sedimentary rocks that consist more than 50vol.% of silt- and clay-sized particles (<62.5 and <4 μm in diameter) ( Folk, 1980 ). In the geological literatures and practices, the term mudrock and/or mudstone is more ... Limestone is a sedimentary rock composed primarily of calcite, a calcium carbonate mineral with a chemical composition of CaCO 3. It usually forms in clear, calm, warm, shallow marine waters. Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris.Calcareous ooze lithifies as lime mudstone, sometimes referred to as pelagic limestone. Below the CCD, only dust and silica can deposit, as the calcareous organisms dissolve before reaching the sea floor, and siliceous ooze accumulates more quickly than red clays.Description. Scheme of the transitional lithotypes from mud (or mudstone) to lime (or limestone), illustrating the definition of marl (marlstone) as a mix of calcium carbonate and clay. Marl or marlstone is a carbonate -rich mud or mudstone which contains variable amounts of clays and silt. The term was originally loosely applied to a variety ...The P 1 f 3 Member comprises silty mudstone, dolomitic mudstone, and grayish-black lime mudstone. The lithological features of the other three boreholes are comparable to those of the MY-1 borehole, except for the large sets of alkaline mineral-enriched sections and dolomitic rocks in the P 1 f 1 Member of the XY-1 and X-203 wells ( Figure 2 ).Jan 19, 2021 · Facies-8: thin-bedded lime mudstone. The facies consist of thin-bedded, pale gray to gray limestone; the bed thickness varies from 5 to 10 cm. The limestone is parallel laminated and has sharp contact with upper and lower units (Fig. 6). The thin section study of limestone reveals that it is composed of more than 80% of lime mud as micrite and ... Calcilutite. Calcilutite (also known as cementstone) [1] is a type of limestone that is composed of predominantly, more than 50 percent, of either clay-size or both silt-size and clay-size detrital (transported) carbonate grains. These grains consist either of fossil fragments, ooids, intraclasts, pellets, other grains, or some combination of them.Dunham classification A widely used limestone classification, proposed by Robert Dunham in 1962, which divides limestones on the basis of their texture and mud content. For limestones which retain their original, depositional texture, the main subdivisions are: lime mudstone (limestone with less than 10% grains in a mud-supported sediment); lime wackestone (limestone with more than 10% grains ...

McKnight divided into three unnamed members. Age is Early Cretaceous (Comanche). [Type locality and origin of name not stated.]In order to investigate the mechanical properties of lime mudstone, conventional triaxial compression tests under different confining pressures (0, 5, 15 and 20 MPa) are performed on lime mudstone samples. The test results show that, from the overall perspective of variation law, the axial peak stress, axial peak strain and elastic modulus of ...A. Nodular lime mudstone and yellowish-gray shale.

F4: Calcareous shale and argillaceous lime-mudstone to packstone: shale-dominated inner-lagoonThe Jubaila Formation (Upper Jurassic) in central Saudi Arabia has been divided into lower, middle, and upper parts purely on lithologic grounds. Each part consists of a major lower unit of lime mudstone and a minor upper unit of grainstone. This persistent change in the limestone facies is interpreted as a reflection of repeated shoaling up in the depositional shelf environment.

Apr 5, 2022 · Because it was near the front of the Lime Mud Deposits? Shallow-water lime muds in today's tropical oceans accumulate at a rate of one foot thickness per one thousand years. These muds are formed by mechanical breakdown of carbonate containing sea creatures. Modern muds are believed by evolutionists to provide an excellent example of how ancient lime mudstones ("micritic limestones") were accumulated in Grand Canyon.The basal carbonate member is an overall deepening up succession of facies associations comprising: Facies Association 1 – siliciclastic-rich heterolithic facies, lime mudstone with desiccation cracks, and plant debris rich carbonate silt interpreted as siliciclastic-rich tidal flats; Facies Association 2 – well-sorted gravels, siliciclastic-rich … The Dam Formation is a mixed siliciclastic-carbonate unit (4

The rationale of this classification is that it allows one to map gradients in rate of production of sand-size particles relative to rate of accumulation of lime mud. In calm waters, lime mud, if present, settles on the bottom and remains there.
