Limestone that contains some dolomite is known as dolomitic limestone. Dolomite is very similar to the mineral calcite or traditional marble. Calcite is composed of calcium carbonate (CaCO 3), while dolomite is a calcium magnesium carbonate (CaMg(CO 3) 2). The best way to tell these minerals apart is to consider their hardness and acid reaction ...
Dolomite and limestone are difficult to tell apart visually; a common field technique for distinguishing them is to drip hydrochloric acid (a hydrous solution of HCl) onto a hand sample. In response, limestone froths vigorously and dolomite weakly. Metamorphosed limestone becomes calcite marble; metamorphosed dolomite becomes dolomitic marble.
Dolomite is a calcium magnesium carbonate with the chemical composition CaMg(CO 3) 2, constituting a rock-forming mineral found in abundance around the world.It has numerous commercial uses. Dolomite mineral is rarely found in modern sedimentary environments; however, dolomite rocks (dolostones) are common in geological history.
Limestone has two origins: (1) biogenic precipitation from seawater, the primary agents being lime-secreting organisms and foraminifera; and (2) mechanical transport and deposition of preexisting limestones, forming clastic deposits. Travertine, tufa, caliche, chalk, sparite, and micrite are all varieties of limestone. Limestone has long …

Limestone is a naturally formed mineral, primarily composed of calcium carbonate (Oates 2008).It forms commonly in shallow, calm and warm marine waters, as found in the Caribbean Sea, the Indian Ocean, the Persian Gulf and the Gulf of Mexico (King 2005).Another way of limestone that forms is through evaporation, with this type …
Marble is a granular metamorphic rock, it is derived from limestone or dolomite and It consists of a mass of interlocking grains of calcite or the mineral dolomite. Form of it when limestone buried deep in the older layers of Earth's crust is subjected to heat and pressure from thick layers of overlying sediments.

Sedimentary rock - Limestones, Dolomites, Calcite: 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 …
When it comes to choosing the right material for your countertops, there are many options available, each with their own unique characteristics. Two popular choices are dolomite and marble. While both are beautiful natural stones, they have different properties that make them suitable for different needs. Here's a comparison of dolomite countertops vs …

Rapid industrial and developmental activities have put the emphasis on opencast mining for greater and economic recovery of minerals. But mining operations not only disrupt the natural ecosystem in a significant way, but also bring about a number of health hazards and socio- economic disturbances to the local people. In the present paper the air and water …
limestone, the days; the schists and the slates, the cement industry is currently flourishing along with the construction industry which depends on these miner als. Finally, coal mining is very extensive and Greece ranks seventh in world production of lignite-brown coal. Nevertheless, mining and metallurgical activity in
Dolomite, also known as dolostone, is a sed-imentary carbonate rock, consisting mainly of the mineral dolomite [CaMg(CO3)2]. Rocks containing only 10–50% of the mineral …
Dolomite vs. Marble: Marble is a metamorphic rock formed from limestone under intense heat and pressure. It primarily consists of calcite or dolomite. It primarily consists of calcite or dolomite. Although both dolomite and marble can be polished to a high sheen, dolomite is generally less susceptible to acid etching, making it more …
Marble is metamorphosed limestone and therefore consists mostly of calcite, although some marbles contain varying proportions of dolomite or calc-silicate minerals. Marble is …
The double carbonate of calcium and magnesium is called dolomite – CaMg(CO 3) 2. In New Zealand, dolomite is only found in the small area of Mt Burnett, near Collingwood in Golden Bay. Marble. When limestone is subjected to considerable pressure and heat, it recrystallises into marble.

Limestone and dolomite have been formed in a variety of settings in Victoria and range in age from early Palaeozoic to Quaternary. Younger limestones tend to be friable and porous, whereas older limestones are often dolomitised and silicified, or metamorphosed and recrystallised to marble.
