Lime mudstone.

Micrite is lime mud, carbonate of mud grade. Micrite as a component of carbonate rocks can occur as a matrix, as micrite envelopes around allochems or as peloids. The origin of micrites is still a problem in carbonate sedimentology due to the non-uniqueness of the processes generating it. [3] Micrite can be generated through multiple processes.Mudstone is made up of fine-grained clay particles (<0.05mm) compressed together. Mudstones form where clay has settled out in calm water - in lakes, lagoons, or deep sea. Flaky mudstone is called shal The results from thermal maturity modeling are in agreement with the geochemical data that indicate that Upper Jurassic Smackover lime mudstone served as an effective regional source rock throughout the basin, and that the Lower Cretaceous marine shales were effective local source rocks given the proper organic facies.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 Shale: Exhibits lamination or fissility. Argillite: It has undergone low-grade metamorphism. Clastic sedimentary rocks are classified by size of the sediment particles making up the rock. Particle size descriptions like sand, silt, and clay have specific meaning in geology and engineering.Mudstone is made up of fine-grained clay particles (<0.05mm) compressed together. Mudstones form where clay has settled out in calm water - in lakes, lagoons, or deep sea. Flaky mudstone is called shal 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.To describe the axial stress–strain behavior in failure process of lime mudstone, a new constitutive model is proposed, with the model characteristics …Marlstone is usually pale grey or white; it has a blocky subconchoidal fracture, and is less fissile than shale.
