What is Marble? Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. It is composed primarily of the mineral calcite (CaCO 3) and usually contains other minerals, such as clay minerals, micas, quartz, pyrite, iron oxides, and graphite.. Under the conditions of metamorphism, the calcite in the …

Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don't dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3- ions, which are very soluble in water, and the limestone will dissolve. Or, if there is …

Crystalline Limestone. Crystalline limestone is a carbonate sedimentary rock that is composed of the precipitation of the mineral calcite ((ce{CaCO3})) from saturated sea water. Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate ((ce{CaCO3})).
