Lime mudstone

Jan 1, 2013 · Instead, the fine- size carbonate rock is called mudstone (better, lime mudstone) . 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.

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.... lime mudstone (limestone with less than 10% grains in a mud-supported sediment); lime wackestone (limestone with more than 10% grains in a mud-supported ...The upper cycle is made up of shallow sub-tidal embayment lime-mudstone shallowing-up to breccciated Paleosol, which is the sequence boundary of KC3.

The characteristic feature of this microfacies type is the occurrence of partly rounded limestone nodules embedded in a muddy, fine-bioclastic, marly matrix (Fig. 7g). The ...

Thin beds of lime wacke-mudstone and intermittent skeletal wackestone break up these larger beds. Both the lime mudstone and wacke-mudstone become barren for a span of almost 30 meters up-section. The presence of these thick mudstones suggests that the platform deposition slightly lagged accommodation due to sea level rise coupled with …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.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.It consists of lime mudstone-packstone skeletal grain.

Mudstone is distinguished from shale by its lack of fissility (parallel layering). The term mudstone is also used to describe carbonate rocks (limestone or dolomite) that are composed predominantly of carbonate mud. variable in lithofacies, from lime mudstone to oolitic grainstone. Generally, it is partially to totally dolomitised, and the thickness varies from 20 to 50 m. The Benifallet consists of metre-scale shallowing-upward, coarsening-upward parasequences.

Clastic sedimentary rock. Mudstone. Lime-mudstone. Calcite-mudstone. Biochemical and chemical sedimentary rock.Limestones deposited in downslope or in basinal positions possess several distinctive criteria based on microfacies, bedding, and fauna. The microfacies include (1) homogeneous lime mudstone, (2) millimeter laminated lime mudstone, and (3) common micropelletoid lime grainstone (calcisiltite). The latter may show fine ripple cross-lamination. The Dunham classification system for carbonate sedimentary rocks was originally devised by Robert J. Dunham in 1962, [1] and subsequently modified by Embry and Klovan in 1971 [2] to include coarse-grained limestones and sediments that had been organically bound at the time of deposition. The modified Dunham Classification has subsequently ... The 12 lithologies recognized within the stratigraphic sections reflect the interaction between contemporaneous shallow-water carbonate ramp environments and a siliciclastic-dominated intrashelf basin. Deposition on the carbonate ramp was in the form of lime mudstone and wackestone and oolitic and oncolitic packstone and grainstone.The lime mudstone occurs as lentoids or bands of approximately 0.2–2m in thickness and ranges in length from about 5m to more than 30m in length in the outcrops.Clan designation. As others before him, Folk proposed a classification for sandstones based on the relative abundances of quartz (Q), feldspars (F), and rock fragments (R). These are the main poles of the classification diagram. To define the clan name one must normalize the sum of abundances of quartz, feldspars and rock fragments to 100%.Calcirudite consisting of grains > 2 mm (lime-rubble) and representing the carbonate parallel of a conglomerate. Several authors use calcirudite irrespective of the rounding of grains, but some authors use lime-breccia for limestones with angular clasts. Calcarenite is a limestone with sand-sized (0.0625 – 2 mm) carbonate grains (lime-sand).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 stre …The overlying Lower Triassic strata contain microgastropod lime-packstones followed by a thick succession of thin-bedded lime-mudstones. ...
