Caliche (/ k ə ˈ l iː tʃ iː /) (unrelated to the street-slang "Caliche" spoken in El Salvador) is a soil accumulation of soluble calcium carbonate at depth, where it precipitates and binds other materials—such as gravel, sand, clay, and silt.

2017年1月31日 · Caliche is an accumulation of calcium carbonate that is deposited as part of the formation of soil; Caliche in our area can be up to 3 feet thick, or more, but generally is about 1 foot thick

"Caliche" is a shallow layer of soil or sediment in which the particles have been cemented together by the precipitation of mineral matter in their interstitial spaces. The cement is usually calcium carbonate; however, cements of magnesium carbonate, gypsum , silica, iron oxide, and a combination of these materials are known.

2024年8月16日 · Caliche soil, characterized by its whitish-gray or cream color, is formed through the cementation of calcium and magnesium carbonates. It can exist in various forms, such as a soft and thin soil horizon, a hard and thick bed, or even as a layer revealed by erosion.

Managing Caliche in the Home Yard Caliche is a common problem in southern Arizona soils. Caliche is layer of soil in which the soil particles are cemented together by calcium carbonate (CaCO 3). These layers may form at or below the soil surface. Caliche may appear as light colored concretions (lumps) which range in size from less than 1 inch to

2025年3月5日 · What is Caliche? Caliche, often called "hardpan," is a natural cement formed from calcium carbonate. Found in arid regions, it creates a tough, crusty layer just below the soil surface. This layer can be a gardener's nightmare but a geologist's treasure. Why does it matter? Caliche impacts agriculture, construction, and even archaeology.

Caliche is a whitish-gray or cream-colored soil layer that has been cemented by carbonates of calcium and magnesium. Caliche may occur as a soft, thin soil horizon (layer); a hard, thick bed; or a layer exposed to the surface by erosion (SSSA, 2001).

Caliche is a general term given to deposits of secondary calcium carbonate widespread throughout arid and semi-arid regions. Although all such deposits are chemically similar—dominantly calcite—the physical properties, distribution, and degree of development vary due to different modes of formation.

caliche 意思是: 硬化土; 1858年，智利和秘鲁的硝酸钠沉积物，来自南美西班牙语，源自西班牙语caliche“砖块中意外封闭的卵石；石灰片”，源自拉丁语calx“石灰石，卵石”（见chalk（n.））。

Caliche is a type of sedimentary rock that forms when calcium carbonate or lime accumulates. This natural cementing material is found in arid and semi-arid climates around the world. Caliche typically forms a hard, compacted layer that’s several feet thick. If the caliche is exposed to water or other moisture, it may dissolve and form a soft mud.
