Lime 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.After comparing them with the well logs, electrofacies are identified as the following main limestone facies (mudstone, mudstone–wackestone, wackestone, …The lime mudstone exhibits sharp contact with fine layers, displaying planar cross-bedding, indicating an important changing level in the environmental energy during sedimentation (Fig. 7, Fig. 8). Generally, the content of siliciclastic sediment in the carbonate rocks increases from the base to the top, not in a common way but not in a ...A mudstone is a siliciclastic sedimentary rock that contains a mixture of silt- and clay-sized particles (at least 1/3 of each). The terminology of "mudstone" is not to be confused with the Dunham classification scheme for limestones. In Dunham's classification, a mudstone is any limestone containing less than ten percent carbonate grains.

The Permian basin of west Texas and Southeastern New Mexico is one of the major petroleum producing regions of the United States. This basin produced 3% of the world's petroleum in 1984 and in that year, 1% of the world's proven reserves were in the Permian basin (Robichaud, 1989). Most of the Upper Permian hydrocarbon reservoirs are in San …Name McKnight is preferable to name Kiamichi for the sequence of black shaly limestone in Maverick basin because of lithologic difference and deposition in a different basin from the Kiamichi. McKnight divided into three unnamed members. Age is Early Cretaceous (Comanche). [Type locality and origin of name not stated.]Sandy lime-mudstone. Sandy lime-mudstone microfacies occur in three or four beds at the Wadi Huraymila, particularly in the basal and upper parts of Jubaila Formation. Each bed ranges from 3 m to 3.5 m in thickness and creates the basal part of cycles. This microfacies are sandy, yellowish-brown, and gray in color.

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 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 ... 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%.The basal contact is gradual in the Middle Grainstone plus Upper Lime Mudstone Members of the Cacarajícara Formation and the Upper Unit of the Peñalver Formation at the type locality, whereas the basal contact is an erosional surface at the other shallower sites, including the Upper Unit of the Peñalver Formation at Cidra and the Santa ...For limestones which retain their original, depositional texture, the main subdivisions are: lime mudstone (limestone with less than 10% grains in a mud …Oct 13, 2023 · Quick Reference.

Chalk is a soft white limestone made from the …Mudstone, a type of mudrock, is a fine-grained sedimentary rock whose original constituents were clays or muds. 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.Mudstone - hardened mud; a mix of silt and clay sized particles.
