Quarrying. Imagine thick layers of materials – mud, sand, ash, lava, and more – laid down over millions of years, new on top of old. Imagine the materials in these layers changed by heat and pressure, and then squeezed up into a dome. Imagine the top of the dome eroded by weather to expose the oldest layers in the centre, whilst remaining ...

Limestone is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3). Dolomite, CaMg(CO 3) 2, is an uncommon mineral in limestone, and siderite or other carbonate minerals are rare. However, the calcite in limestone often contains a few percent of magnesium.Calcite in limestone is divided into low-magnesium and high-magnesium ...
Limestone can be damaged by the environment through weather and water erosion. The stone absorbs water that can cause it to deteriorate over time. If the water has a high acidity content, the damage is more immediate. Wind can wear away stone detailing. Limestone is also prone to discoloration by exposure to oil, dyes or even organic material ...

Interesting Facts – Limestone. Limestone is a sedimentary rock composed mainly of the mineral calcite, which is a crystalline form of Calcium Carbonate (CaCO3). Limestone often contains variable amounts of silica in the form of Jasper or Flint, as well as amounts of clay, silt, and sand as disseminations, nodules, or layers within the rock unit.
Limestone is a sedimentary rock that contains at least 50% calcium carbonate (CaCO3). Because sedimentary rocks are made of various types of sediments, the other 50% of a limestone rock could be virtually any other mineral.
