is limestone detrital or chemical?
6248
Limestone is a sedimentary rock. It forms predominantly on the sea floor where material rich in calcium carbonate ('calcareous' material) accumulates. This calcareous material may be organic, chemical or detrital in origin.

The main component of chalk is calcium carbonate (CaCO 3 ), a form of limestone. Limestone deposits develop as coccoliths (minute calcareous plates created by the decomposition of plankton skeletons) accumulate, forming sedimentary layers.

The commonly assumed density of 3150 kg/m3 (3.15 g/cm3) for portland cement [4] will not be correct when limestone is interground into the cement. Neither ASTM C150 nor ASTM C595 requires the density to be reported or measured.

Erosion is the process where rocks are broken down by natural forces such as wind or water. There are two main types of erosion: chemical and physical. Chemical erosion occurs when a rock's chemical composition changes, such as when iron rusts or when limestone dissolves due to carbonation.

Chemical weathering, such as acid rain, eats away at certain types of rocks such as limestone, creating cracks and holes. ... Mechanical weathering is weathering caused by the breaking down of rocks by physical force without any change in the chemical nature of the rocks.

Marble chips (White Limestone) are mostly made up of calcium carbonate, which is an alkaline compound. Being alkaline, it reacts with hydrochloric acid to produce calcium chloride, water and carbon dioxide.

Dolomite is most often used limestone as it contains equal parts of magnesium and calcium. Lime is used to increase the soil's pH and decrease acidity. By neutralizing acidic soil, plants can easily absorb nutrients from the soil. Lime also improves soil texture and helps convert other soil nutrients into usable forms.

Dolomitic Limestone mostly consists of magnesium calcium carbonate CaMg(CO3)2, whereas regular Limestone mainly consists of calcite and aragonite (CaCO3), which are just two different crystal forms of calcium carbonate.

1) Clastic (detrital) sedimentary rocks are composed of the solid products of weathering (gravel, sand, silt, and clay) cemented together by the dissolved weathering products.

Explanation: In the given options, marble, limestone, and baking soda are all either metal carbonates or bicarbonates. All these when react with a dilute acid then they produce carbon dioxide. Whereas lime which is calcium oxide when react with a dilute acid then they do not produce carbon dioxide.

Gypsum & Limestone: two great soil amendments with key differences. Gypsum is calcium sulfate, and lime is calcium carbonate. Both are soil amendments, and both provide calcium. ... Gypsum is also an industrial byproduct from coal-fired power plants, citric and lactic acid plants and water treatment plants.

The commonest varieties, calcite, dolomite, and aragonite, are prominent constituents of certain rocks: calcite is the principal mineral of limestones and marbles; dolomite occurs as a replacement for calcite in limestones, and when this is extensive the rock is termed dolomite; and aragonite occurs in some recent ...

Detrital Sedimentary Rocks The word 'detrital' actually means 'rubbing away,' and we see that detrital rocks form when pre-existing rocks are rubbed away or weathered by forces such as water, ice and wind, leaving behind smaller rock fragments.

Pure limestones are white or almost white. Because of impurities, such as clay, sand, organic remains, iron oxide and other materials, many limestones exhibit different colours, especially on weathered surfaces. Limestone may be crystalline, clastic, granular, or dense, depending on the method of formation.

Calcite is a form of calcium carbonate with the chemical formula CaCO3. Calcite is a form of calcium carbonate with the chemical formula CaCO3.

As two rocks are not same, it's fun to compare them. ... Limestone is a sedimentary rock composed mostly of calcite and aragonite, which are different crystal forms of calcium carbonate. Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds.

3(c) were generated during dry-slaked lime process with water to transform nearly all of the CaO to Ca(OH)2. On the other hand, calcium hydroxide reacts spontaneously with CO2, forming CaCO3 which is the most stable compound in the lime cycle.
