• Limestone - Wikipedia

    en.wikipedia.org/wiki/Limestone Coastal limestones are often eroded by organisms which bore into the rock by various means. This process is known as bioerosion. It is most common in the tropics, and it is known throughout the fossil record (see Taylor and Wilson, 2003). Bands of limestone emerge from the Earth's surface in often spectacular rocky outcrops and islands.

    www.britannica.com/science/limestone Limestones enriched in phosphate by the chemical action of ocean waters constitute a principal source of raw materials for the fertilizer industry. When heated to temperatures of 900 to 1,000 °C (1,650 to 1,800 °F), limestones will dissociate calcium carbonate and yield carbon dioxide and lime, the latter having major applications in the ...
  • Limestone: Rock Uses, Formation, Composition, Pictures

    geology.com/rocks/limestone.shtml Limestones formed from this type of sediment are biological sedimentary rocks. Their biological origin is often revealed in the rock by the presence of fossils. Some limestones can form by direct precipitation of calcium carbonate from marine or fresh water. Limestones formed this way are chemical sedimentary rocks.

    www.sandatlas.org/limestone Limestone is a very common sedimentary rock consisting of calcium carbonate (more than 50%). It is the most common non-siliciclastic (sandstone and shale are common siliciclastic rocks) sedimentary rock.Limestones are rocks that are composed of mostly calcium carbonate (minerals calcite or aragonite). Carbonate rocks where the dominant carbonate is dolomite (calcium magnesium carbonate) are ...

Limestones usually form in deep ocean waters. In the Michigan basin, limestones formed at many different times, when the basin was filled with water of varying depths.

    www.wisegeek.com/what-is-limestone.htm Some limestones are composed of small grains of material which have been compressed, while others have crystalline structures upon magnification. These variations are influenced by the stone's formative processes, as is the color, which can be white, yellow, green, pink, cream, black, rust, brown, or any other color imaginable, depending on ...
