Marble Rock: Geology, Properties, Uses - ThoughtCo

Marble is a metamorphic stone formed by subjecting limestone to heat or pressure. In pure form, marble consists of calcium carbonate (calcite) and is sparkling white. Impurities produce pale gray, brown, or variegated colored rock. Black marble also occurs. Marble takes a high polish.

Marble is metamorphosed limestone, that is, limestone that has been melted and allowed to resolidify. If the original limestone is a calcite limestone, then the marble is a calcite marble (i.e., mostly CaCO3); if the original limestone is a dolomitic limestone, then the marble is a dolomitic or magnesian marble (i.e., mostly CaMg(CO3)2).

If 10 kg of oak is heated from 20 oC to 50 oC - a temperature difference 30 oC (K), the heat required can be calculated as q = (2 kJ/kg K) (10 kg) (30 oC) = 600 kJ If one hour (3600 s) is used to heat the oak - the power required can be calculated with the equation P = q / t (2) where P = power (kJ/s, kW) t = time (s) With values:

What is Gypsum? Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite. Gypsum (CaSO 4. 2H 2 O) is very similar to Anhydrite (CaSO 4 ). The chemical difference is that gypsum contains two waters and anhydrite is without water.
