Dolomite contains nearly equal amounts of magnesium and calcium. Most dolomites formed as a magnesium replacement of limestone or lime mud before lithification. Dolomite is less soluble than limestone and, for identification purposes, must first be scratched into a small power before it will effervesce with dilute hydrochloric acid.

What is Limestone? "Limestone" means any rock formed mostly of calcium carbonate (CaCO 3), but to geologists, limestone is only one of several types of "carbonate rocks."These rocks are composed of more than 50% carbonate minerals, generally the minerals calcite (pure CaCO 3) or dolomite (calcium-magnesium carbonate, CaMg[CO …

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 …
Dolomite forms through a complex process known as diagenesis, where magnesium-rich groundwater interacts with calcium carbonate in existing limestone deposits. This interaction results in the replacement of some calcium ions with magnesium ions, leading to the formation of dolomite crystals.
The guidance of limestone or dolomite is most intense on the ground at the first contact of water with the rock. Aggressive can also be experienced in ground joints, rounds and bedding, as well as while targeting spherical joints, rounds and hovering over the water table, which also follows the same course. ...

Dolostone is the most important rock type that is composed mostly of it. Dolostone was probably originally limestone which was altered by Mg-bearing water circulating in the rocks. Dolomite does not precipitate out of aqueous solutions like calcite does (in normal circumstances). Carbonate rock is dolostone if at least 50 percent of it is dolomite.
The Acid Test on Rocks. LIMESTONE, DOLOSTONE, AND MARBLE. Some rocks contain carbonate minerals, and the acid test can be used to help identify them.

The third area around Salalah has proven deposits of limestone, dolomite and gypsum, with potentially exploitable deposits of clays and silica. Oman is a major producer of limestone, with some 8.3m tonnes of output in 2021. However, output has dropped from a high of 19m tonnes in 2017 due to resources becoming depleted.

Limestone is therefore an essential part of the batch. However, limestone comes in two basic types: high calcium and dolomitic. The difference between the two relates to the relative magnesium (Mg) content. High-calcium limestone is almost entirely CaCO 3 with 1%—3% impurities.
