How Is Marble Formed From Limestone? - Reference

Mar 30, 2020· When the heat and pressure hits the limestone, calcite seed crystals form. With continued metamorphism, these crystal seeds, grow while any clay deposits in the limestone transform into silicate structures such as mica. Because marble is a fairly soft material, only a three on the Mohs hardness scale, it is easy to cut and carve.

Limestone and limestone caves — kidcyber

Limestone is a sedimentary rock. It is formed by layers of small pieces of rock and stones pressed hard together. The stone forms in wet areas which means it also contains shells and waste matter from organisms that live in water. Limestone caves are formed when rainwater seeps through cracks in limestone rock and dissolves it.

What happens when acid reacts with limestone? | Questions ...

Jun 15, 2008· 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 more acid, two hydrogen ions will
