Most recently, this definition has been clarified as a matrix-supported carbonate-dominated rock composed of more than 90% carbonate mud (<63 μm) component. [3]Limestone and lime mudstone exposed in the northeast Taylor Mountains and southeast Sleetmute quadrangles. Unit consists of distinctive limestone lithologies, boundstone and packstone to wackestone, interspersed with the mudstone: the stratigraphically lowest part of the unit is thin- to medium-bedded, dark-gray, yellow-gray-weathering, burrow-mottled lime mudstone and lesser peloidal mudstone.

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.A typical chalk is a fine-grained carbonate rock (a lime mudstone or micrite), the lithified equivalent of pelagic carbonate oozes recorded from ODP boreholes in present-day oceans. The sediment is dominated by debris derived from coccolithophorid algae that comprise a spherical calcareous test (coccosphere) up to several tens of microns in ...

Lime mudstone microfacies This microfacies is a less common facies in the carbonates of the Tanjero Formation in the Hujran section (Fig. 10 ), which is characterized by containing grains less than 10% in micrite matrix (Dunham 1962 ).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).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 ).Limestone & Chalk. Limestone is made up of calcium carbonate (fizzes with acid). This may be shell fragments, mud, or small, round ooliths that form in tropical lagoons. Chalk is a soft white limestone made from the microscopic skeletons of marine plankton.The microfacies include (1) homogeneous lime mudstone, (2) milli- meter laminated lime mudstone, and (3) common micropelletoid lime grainstone (calcisiltite).

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.

Flaky mudstone is called shalThe 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).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.
