Limestone: composed of sedimentary rock, it is harder and more dense than chalk and is made of a blend of calcite and aragonite. Limestone is typically extracted from the earth's crust either by blasting or mechanical excavation, which method is used depends on the hardness of the rock. Then the rock is crushed roughly.

Limestone. Limestone forms by sedimentation, of coral and shells (biological limestone) or by the precipitation of calcium carbonate (as calcite and aragonite), in marine waters. It comes in many forms (e.g. chalk, coquina, fossiliferous, lithographic, oolitic, travertine, tufa). It can be crystalline, clastic, granular or massive.

Calcite, or calcium carbonate, is the primary mineral found in limestone, and its parent metamorphic rock, marble.It's really found just about everywhere, but it's found in higher concentrations within those two rocks.. Looks can be deceiving, and there are many minerals that look similar to calcite, and it also comes in so many aesthetics.

Limestone is a sedimentary rock that is composed primarily of calcite. It forms from both the chemical precipitation of calcium carbonate and the transformation of shell, coral, fecal and algal debris into calcite during diagenesis. Limestone also forms as a deposit in caves from the precipitation of calcium carbonate.

# ID tip # Calcite can be scratched by a knife, but then so will other soft white minerals. Better test is a small squirt bottle of 10% HCl (or muriatic) acid. Calcite = limestone (the biological rock of life) and it will fizz like soda pop. Don't fizz-test the exposed surface of your nice show specimen though!

Limestone is made of almost pure calcite. When these sediments are buried during subduction into the Earths crust or get into the contact with hot magma, they are metamorphosed into marbles or calc-silicate rocks. Sometimes the sediments are buried so deep that they melt into carbonate magma and create carbonatite rocks.

Calcite can form rocks of considerable mass and constitutes a significant part of all three major rock classification types. It forms oolitic, fossiliferous and massive limestones in sedimentary environments and even serves as the cements for many sandstones and shales. Limestone becomes marble from the heat and pressure of metamorphic events.
