Limestone, as used by the minerals industry, is any rock composed mostly of calcium carbonate (CaCO 3). Although limestone is common in many parts of the United States, it is critically absent from some. Limestone is used to produce Portland cement, as aggregate in concrete and asphalt, and in an ...

The rock forming the earth''s crust falls into three generic group''s: igneous, sedimentary and metamorphic. Heat, pressure, and chemical reactions may change either igneous or sedimentary ...
History Original classification. Robert J. Dunham published his classification system for limestone in 1962. The original Dunham classification system was developed in order to provide convenient depositionaltexture based class names that focus attention on the textural properties that are most significant for interpreting the depositional environment of the rocks.
Indiana Limestone, which is a Mississippianage grainstone of very uniform texture and grade, has gained worldwide acceptance as a premier dimension stone. The Salem Limestone, which is the geologic formational name for this carbonate unit, crops out in a belt that trends southward from Stinesville in Monroe County to Bedford in Lawrence County.

A technical report can provide a description of the geological characteristics of a specific area or region. Geological reports may be very detailed or brief, depending on the project and its level of complexity. Professional geological engineers write reports about observations and investigations. Students can also ...
Introduction. Most of the upper Desmoinesian, Missourian, and lower Virgilian sequence of the midcontinent MiddleUpper Pennsylvanian outcrop belt has been subdivided into an alternation of dominantly marine limestone formations with thin shale members and dominantly terrestrial to nearshoremarine shale formations with coal beds and local sandstone members (fig. 1).
Jul 30, 2018· One limestone name, travertine, is known to those who installed this upscale tile in their homes, but it is only one of type of limestone. As a sedimentary rock, limestone mostly consists of clay, calcite, calcium carbonate and the shells and exoskeletons of marine line and other invertebrates.
Rocks formed dominantly from this material are the biochemical version of limestone. Since the principal compound making up limestone is CaCO3, geologists refer to limestone as a type of carbonate rock. Limestone comes in a variety of textures, because the material .
The objective of this chapter is to evaluate some of the proposed classifications of sedimentary carbonate rocks, and to present suggestions for naming and describing them. It is not an historical review of existing schemes of classification alone, although a critical appraisal has been made of the various systems that have been published in ...

Most limestones are classified by Folk allochemical Rocks if they contain over l0% allochems (transported carbonate grains). Based on the percentage of interstitial material, the Rocks may be further subdivided into two groups: sparry allochemical limestones (containing a sparry calcite cement of clear coarsely crystalline mosaic calcite crystals) and microcrystalline allochemical limestone ...

''Massive limestones'' are those that are made of thick layers (called ''beds'') of rock. In England, these limestones are the older and harder types, such as the Carboniferous limestone. The massive Carboniferous limestones originally accumulated in a warm shallow sea when Britain lay much closer to the equator than it does now.

As currently defined, the Paoli comprises the rocks between the Ste. Genevieve Limestone (below) and the Bethel Formation, but the Paoli of Elrod (1899) included the rocks above the Lost River Chert Bed, in the lower part of the Ste. Genevieve, and below the lowest Chesterian sandstone, which at that time was incorrectly thought to be what is ...

All classifications of limestones tend to be rather arbitrary and they frequently overlap or do not fit one''s particular needs. Since binocular microscopes or hand lenses are the tools that are commonly available to the professional or academic geologist, a practical classification should be based on descriptions that use these tools.
as sediment is buried beneath more sediment or other materials the increasing pressure pushes clasts together, called compaction. compaction forces out excess water and causes sediments to lose as much as 40 percent of their volume. as the sediment is buried, minerals can precipitate from from water moving through pore space, coating the surfaces of the grains and sticking them together.

The chemical formula of calcite is CaCO3. Geologists can use an acid such as HCl for the following reaction. CaCO3 + 2H (+) + 2Cl () ⇒ Ca (2+) + 2Cl () + H2CO3 The H2CO3, however, immediately decomposes into H2O and CO2, so by determining that gas is being emitted, aka it is bubbling, they can determine that it is limestone.
