mészkövet

Mészkő, also known as limestone, is a sedimentary rock composed primarily of the mineral calcite (calcium carbonate, CaCO3). It is formed by the accumulation of shells, coral, algal, and fecal debris. Most limestone is formed in warm, shallow marine environments. It can also be formed by precipitation from groundwater. Mészkő is a very common rock, found in many parts of the world.

The color of mészkő can vary from white to gray, or even black, depending on the impurities present. It often contains fossils, which can provide valuable information about past life and environments. Mészkő is a relatively soft rock, with a Mohs hardness of about 3. It is soluble in dilute acids, which is a characteristic property used for its identification.

Mészkő has a wide range of uses. It is a major component in the production of cement and building materials. Crushed mészkő is used as aggregate in concrete and road construction. It is also used in agriculture as a soil conditioner to neutralize acidity. In industry, mészkő is used in the production of lime, which has applications in steelmaking, water treatment, and the chemical industry. Furthermore, mészkő formations, such as caves and karst landscapes, are important geological features and tourist attractions.
