The annual production of limestone, estimated to be more than 6.6 Gt from deposits scattered all around the world, is about 9% of the world production of mineral raw materials (around 44 Gt yr −1), and is of the same order of magnitude as coal (7.3 Gt yr −1).

Limestone deposits exist in all continents of the earth. Despite the common and traditional reference to "travertine marble", travertine is really a type of limestone. It is actually the terrestrial (land) formed version of limestone, as opposed to the marine based formations of many other limestone varieties.

Early limestone deposits were formed from the reaction of carbonic acid (H20 + CO2 = H2CO3) with lime and had no biological origin. $endgroup$ – BillDOe. Commented Aug 9, 2015 at 20:25 $begingroup$ @BillOer ok, and this process still exists today but in a little proportion compared to biogenic limestone. $endgroup$

The land that is now Ireland then moved north close to the equator, at this time, known as the Carboniferous period, a sea extended across Ireland allowing for the for the formation of sedimentary rocks such as sandstone and mudstone. Over the next 50 million years limestone deposits formed in the warm waters.

What is Limestone? Limestone is a sedimentary rock composed primarily of calcium carbonate (CaCO3) derived from the remains of ancient marine organisms such as coral, shells, and microorganisms. Over millions of years, these organic materials accumulate and undergo compaction and cementation to form limestone deposits. Characteristics of …

Rondi: Let's meet Limestone.Limestone is a sedimentary rock made almost entirely of fossils. Fossils are the remains of ancient plants and animals, like an imprint in a rock or actual bones and shells that have turned into rock. Fossils are found in sedimentary rocks and hold the clues to life on Earth long ago.

Calcium carbonate limestone, which is also recognized as the chemical compound CaCO3, makes up almost five percent of the earth's crust and is found all throughout the planet.
