Lime mudstone
This facies overlies gradationally the wackestone-mudstone alternation and consists predominantly of wackestone. The average thickness of the facies varies from 1.6 to 2.9 m. The facies exhibits distinct nodularity in wackestone beds, which locally grades into packstone. The nodules are primarily made up of lime mudstone.133 1-8o: 1Q fan slope and rise; rift_passive_margin; dark grey limes mudstone or fine-grained skeletal wackestone, sharp, planar mudstone wackestone bed contact on one surface, large gutter cast, one large graptolite; dark colour, and pelagic fossils suggest toe of slope or basinal facies, but still within the carbonate compensation depth, gutter cast …

Because it was near the front of the beach bar, lithologies were mainly gray (green)-layered or massive argillaceous siltstone, silty mudstone, and lime mudstone. During the sedimentary period of E 1 f 2 4 and E 1 f 2 3, water expanded rapidly, water stratification strengthened, and salinity and reducibility increased. The lithologies were ...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 ... For limestones which retain their original, depositional texture, the main subdivisions are: lime mudstone (limestone with less than 10% grains in a mud …Mudstone, sedimentary rock composed primarily of clay- or silt-sized particles (less than 0.063 mm [0.0025 inch] in diameter); it is not laminated or easily split into thin layers.

Middle Miocene: The sea level continued to rise during this period. Clastic supply also continued into the basin.Its type locality is Solnhofen (BSPGM Munich coll), which is in a Tithonian lagoonal/restricted shallow subtidal lime mudstone in the Solnhofen Formation of Germany.

Mudstone matrix is generally uniform. In some cases,MT 7 (Fig. 9 E and F) represents a lime mudstone with a few thin-shelled bivalves, fine bioclasts, benthonic foraminifers, and numerous bioturbations. MT 8 (Fig. 10 A and B) represents a foraminiferal-bioclastic wackestone with numerous benthonic foraminifers, gastropods, thin-shelled bivalves, echinoids, and other bioclasts.The main microfacies is dolomitized lime mudstone and contains Valvulina sp. and pelecypods. The concretions are affected by selective diagenesis that resulted in the colour changes between the centre and outer rims of the concretions. X-ray diffraction (XRD) analysis of concretions and host rocks revealed the presence of dolomite, calcite ...The Lower Member (105–120 m thick) consists of thin-bedded limestones such as limestone–shale/marlstone alternation, thin-bedded lime mudstone, laminated calcisiltite, and limestone conglomerates, and thick beds of microbialites (ca. 10 m thick) and grainstones (10–20 m thick).
Limestones. Limestones are made up largely of calcite (calcium carbonate) as their main mineral. Limestones fizz when a drop of dilute hydrochloric acid is placed on them. Uses of Limestone.Lime mudstone (LM) Thinly bedded to nodular lime mudstone with continuous to discrete wavy clayey partings Moderately bioturbated in some beds Rare disarticulated to whole fossils (trilobites, pelmatozoans, ostracods, sponge spicules, gastropods, & nautiloids) Local to common intercalation of P/GJul 1, 2016 · Mudstone: indurate, hard, non-laminated mud forms mud stone.(silt + clay+ water together constitute mud) .

The present study describes the sucessions of the Burdigalian stage, which includes: Euphrates, Dhiban Formations and intervening of Serikagne Formation with Euphrates Formation. Numerous microfacies are identified, based on different criteria. The microfacies of Euphrates Formation are: algal lime mudstone - wackestone, algal lime wackestone …Massive lime mudstone without bioturbation, subaerial exposures and sedimentary structures generated by wave or current, as well as the absence of organisms, combined with thin-bedded lime mudstone of intra-mounds indicate that deposition took place in a low-energy environment, likely below the photic zone.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. Khuff-C Sequence 3 (KC3) is made up of 10 cycles with four initial transgressive peri-tidal cycles of lagoonal dolomudstone capped by crinkly laminated to mud-cracked dolomudstone tidal flat facies.…

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.
