Desmond explains what limestone is, how it's used, and where it comes from.The Kenny Hill Formation was deposited on the eroded surface of the Kuala Lumpur Limestone Formation during the Permo-Carboniferous period, resulting in an angular unconformity. A second phase of folding occurred, possibly during the Jurassic, resulting in additional deformation of Lower Palaeozoic rocks.Common sedimentary rocks include sandstone, limestone, and shale. These rocks often start as sediments carried in rivers and deposited in lakes and oceans. When buried, the sediments lose water and become cemented to form rock. Tuffaceous sandstones contain volcanic ash.

Carboniferous Limestone is a hard sedimentary rock made largely of calcium carbonate. It is generally light-grey in colour. It was formed in warm, shallow tropical seas teeming with life. The rock is made up of the shells and hard parts of millions of sea creatures, some up to 30 cm in length, encased in carbonate mud.Limestone and dolostone are collectively referred to as carbonates because these two sedimentary rock types consist mainly of the minerals calcite (CaCO3 ), aragonite (CaCO 3 ), and dolomite [CaMg (CO 3) 2 ]. The term dolostone, proposed to specifically refer to the rock type composed of the mineral dolomite, has not gained wide usage, and ... Geology. Limestone is a common sedimentary rock that is composed mostly of the mineral calcite (CaCO3). It is produced by crystallization from water, or by accumulation of shells and shell fragments.

Fossiliferous limestone is a sedimentary rock even though it may appear to be a ...

Limestone forms in a deep marine environment from precipitation of calcium carbonate. Shale is made of fine clay particles, and therefore indicates deposition in relatively still water. In contrast, sandstone is made of slightly larger grains and therefore deposition of sand can happen in water that is moving slowly.Shelly limestone is made up of the shells and skeletons of invertebrates that live in the sea (or sometimes in fresh water).
