Mixed siliciclastic and carbonate sedimentation within ...

Intraclastic limestone, thin fossiliferous limestone, and oolitic limestone interbedded with fissile shale are characteristic of the Nolichucky Shale (Upper Cambrian) in the Whiteoak Mountain thrust sheet, eastern Tennessee. These lithologies are interpreted as slope and basinal units deposited in water depths that may have exceeded 250--300 m.

Sedimentary rock

Sedimentary rock - Sedimentary rock - Limestones and dolomites: Limestones and dolomites are collectively referred to as carbonates because they consist predominantly of the carbonate minerals calcite (CaCO3) and dolomite (CaMg[CO3]2). Almost all dolomites are believed to be produced by recrystallization of preexisting limestones, although the exact details of this dolomitization process ...

Tithonian limestones are rare among the limestone olistoliths. Only one sample of allodapic packstone was identified. The Berriasian-Valanginian olistoliths have more variable facies types: coarse to moderately coarse bioclastic grainstone; peloidal-bioclastic, oolithic-bioclastic, or intraclastic-bioclastic grainstone; charophyte- bearing ...

Limestone

Limestone is formed almost exclusively by organisms in seawater (although there are some freshwater limestones too), either, by direct crystallization of dissolved calcium and carbonate to form shells, or as a by-product of the presence of organisms in seawater (which can alter the overall geochemical setting).

Lithology Tip Sheet

packstone: a limestone composed of grains (ooids, peloids, bioclasts, or intraclasts) and lime mud (micrite). Rock is grain-supported and micrite simply fills in spaces between grains that are in contact with one another. grainstone: a limestone composed of grains, but lacking lime mud (micrite). Spaces between grains are filled with spar (cement).

 · Most limestones are light colored (white, buff, or light gray) and very hard, which makes them easy to recognize in typical coal-bearing rock core. Some varieties of limestone are darker and fine-grained, however, and can easily be confused with shale. The definitive test is to apply dilute hydrochloric acid, which should result in distinctive ...

Limestone

Limestone is a common type of carbonate sedimentary rock is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes have likely been more ...

What Are the Characteristics of Limestone?

 · Limestone is a common type of sedimentary rock with a high calcium carbonate composition. Due to its calcium content, limestone is a soft rock that erodes easily. Like other sedimentary rocks, limestone forms from layers of other material that undergoes compression over time. Because of its calcium carbonate, limestone is an organic sedimentary ...

 · Alternations of thin-bedded limestone and shale, or ribbon rock, commonly occur throughout lower Palaeozoic carbonate successions; however, their formative processes are still unclear. In this study, we discuss the origin of the ribbon rocks of the upper Cambrian Hwajeol Formation, Korea, based on detailed microfacies analysis of a ~ 2-m-thick interval.

Limestone | Types, Properties, Composition, Formation, Uses

Some limestones form from the cementation of sand and / or mud by way of calcite ( clastic limestone), and these often have the appearance of sandstone or mudstone. As calcite is the precept mineral thing of limestone, it will fizz in dilute hydrochloric acid.
