The 111 pages that link to Limestone, each with the reason it gives.

• KarstRelated: Its solubility in slightly acidic water makes limestone a common foundation for karst.

• Calcium carbonateBroader topic: Limestone is the principal geological feedstock for many calcium carbonate products.

• CalciteRelated: Calcite is the principal mineral in most limestone.

• Sedimentary rockBroader topic: It commonly forms from shell material or carbonate precipitation.

• SteelmakingRelated: Its lime helps bind impurities into removable slag.

• Carbonic acidRelated: Carbonic acid in rainwater and groundwater can dissolve its calcium carbonate.

• Blast furnaceRelated: It decomposes to lime, which helps capture acidic impurities in slag.

• Göbekli TepeRelated: Local limestone supplied the blocks and pillars shaped for the site’s buildings.

• SpeleologyRelated: Its solubility in mildly acidic water makes it a common cave-forming rock.

• MarbleNarrower topic: Heat and pressure recrystallize limestone into marble.

• DolomitesRelated: Much of the range consists of carbonate rocks, including limestone and dolostone.

• CarbonateBroader topic: It is a major geological reservoir of carbonate ions.

• Portland cementRelated: Its calcium carbonate supplies much of the calcium in clinker.

• Stone carvingRelated: Its range of hardness and availability have suited both sculpture and building ornament.

• Calcium hydroxideNarrower topic: Heating limestone produces the quicklime that is subsequently slaked to calcium hydroxide.

• SpeleogenesisRelated: Its mineral composition makes limestone especially susceptible to dissolution by acidic water.

• CementRelated: It supplies most of the calcium-bearing raw material used in Portland cement manufacture.

• Great Pyramid of GizaRelated: Most of the pyramid’s core consists of locally quarried limestone blocks.

• SmeltingRelated: In iron furnaces, limestone decomposes and helps remove silica as slag.

• StalactiteRelated: Limestone is the common source of dissolved calcium carbonate in stalactite-forming caves.

• ChalkNarrower topic: Chalk is a fine-grained, soft variety within the broader limestone family.

• Dimension stoneBroader topic: It is quarried in many regions for blocks, cladding, and carved details.

• TravertineNarrower topic: Travertine is a freshwater variety of limestone.

• Underground RiverRelated: Its solubility allows water to carve many underground river networks.

• Carbonate mineralRelated: Calcite-rich limestone is quarried for construction, cement, and industrial feedstock.

• Karst HydrologyRelated: Limestone is a widespread host rock for karst aquifers.

• SinkholeRelated: Limestone dissolves in weakly acidic water and commonly underlies sinkhole terrain.

• SkarnRelated: Limestone is a common carbonate protolith replaced during skarn formation.

• Show CaveRelated: Limestone dissolution creates many caves later adapted for public visits.

• StalagmiteRelated: Limestone is both the dissolved source of calcium and the host rock of many stalagmite caves.

• Dinaric AlpsRelated: Thick limestone formations underlie much of the range and are readily dissolved by water.

• Iron smeltingRelated: In blast furnaces it decomposes into lime, which helps remove silica impurities.

• Joseph BlackRelated: Heating limestone provided Black with evidence that fixed air could be driven from a solid.

• Mammoth CaveRelated: The cave's soluble limestone bedrock made extensive passage formation possible.

• Calcium oxideRelated: Calcining limestone is the principal industrial route to calcium oxide.

• Longmen GrottoesRelated: The cliffs’ workable limestone made extensive carving possible.

• QuarryingBroader topic: It is quarried for building stone, aggregate, and cement manufacture.

• Cave formationRelated: Its calcium carbonate dissolves readily in weakly acidic water, making limestone a common cave host.

• CenoteRelated: Its dissolution and collapse create the openings called cenotes.

• Lechuguilla CaveNarrower topic: Lechuguilla’s passages developed within this soluble host rock.

• ChertCompared with: Chert nodules often form within limestone by silica replacing carbonate sediment.

• Great Sphinx of GizaNarrower topic: The Sphinx was carved from layered limestone with uneven resistance to erosion.

• Postojna CaveRelated: Dissolving limestone created the cave’s passages and chambers.

• SneferuRelated: Limestone formed the core and casing of major pyramids built under Sneferu.

• Carbonate rockBroader topic: It is the most widespread carbonate-rock type.

• Gothic sculptureRelated: Its workability made limestone suitable for detailed figures on Gothic church façades.

• Nefertiti BustRelated: The bust’s core is limestone, shaped before its plaster finish was applied.

• Nullarbor PlainRelated: This rock underlies the plain and is readily dissolved by weakly acidic water.

• PhosphoriteCompared with: Limestone can host phosphate deposits but is dominated by carbonate rather than phosphate.

• GuilinRelated: Its dissolution by water underlies the region’s caves and isolated peaks.
