Refers to soil with a high content of calcium carbonate (chalk) or magnesium carbonate.

limy; formed of a calcium salt; chalky.

the substance contains or resembles calcium carbonate.

Referring to limestone or lime-rich soils.

having a hard, crust-like covering composed of calcium carbonate.

Material composed at least partially of calcium carbonate.

Calcium-bearing rock.

groundwater where tufa (recrystallized calcium and magnesium carbonate deposits) forms.

adj. Composed of, containing, or characteristic of calcium carbonate, calcium, or limestone; chalky.

Containing the compound calcium carbonate.

Made of calcium carbonate.

Of, containing, or like calcite (calcium carbonate).

possessing a sufficient quantity of free calcium carbonate or magnesium carbonate to effervesce carbon dioxide visibly when treated with cold 0.1 normal hydrochloric acid; which contribute to a basic condition.

Said of a substance that contains calcium carbonate. When applied to a rock name it implies that as much as 50% of the rock is calcium carbonate.

Composed of or containing calcium carbonate, calcium, or limestone.

limy, rich in calcium, usually in the form of calcium carbonates.

Calcareous - Rocks that contain up to 50 percent calcium carbonate, such as calcareous shale or calcareous sandstone.

of, like or containing calcium carbonate, calcium or lime

Refers to substances containing or composed of calcium carbonate.

(kal ker' s) A substance that contains calcium carbonate (CaCO3), calcium, or lime.

Used in referring to soil that contains an excess of available calcium, usually in the form of calcium carbonate.

coated with, containing, or like calcium carbonate, chalky; - coral, shell and bone all qualify..

having the qualities of or containing calcium carbonate. In the case of Coral Calcium, having a special digested form of calcium carbonate that is highly bio-available. See Cancer Study for varying results.

Containing calcium carbonate or, less generally, containing the element calcium.

(warning: gratuitous educational content) simply stated, a rock that contains carbonate. Hard shale is probably Calcareous.

consisting of or containing calcium carbonate, calcium, or limestone.

Composed of or containing calcium carbonate or chalk.

(soil): A soil or rock containing calcium carbonate, or related minerals, so that it effervesces (bubbles off CO 2) when treated with acid (cf. dolomite). Usually formed from shells or chemical precipitation, these soils and rocks tend to be coastal in occurrence.

It describes a soil that has sufficient calcium carbonate to cause effervescence after the application of a few drops of hydrochloric acid. The calcium carbonate can either be in the form of carbonate segregations or fine earth. Calcareous is used as a descriptive term for Ferrosols, Hydrosols, Organosols, Rudosols and Tenosols in the Australian Soil Classification ( Isbell, 1996).

adj. Term used to describe a structure, secreted by an organism, that consists of or contains calcium carbonate (CaCO3), e.g., the shell of a bivalve.

chalky, composed of limestone, calcium carbonate, or calcium

Containing calcium carbonate, calcium, or lime, which typically causes an alkaline condition, (a pH greater than 7).

containing base-rich materials or calcium.

Said of a rock containing as much as 50% of calcium carbonate (CaCO3), but also composed of something else; (synonym: limy).

Any substance formed of or containing calcium carbonate. Calcium carbonate can help maintain a high pH in aquarium water.

encrusted (covered) with calcium carbonate

Basic soils containing free calcium carbonate.

Containing lime. Calcareous springs may, under the action of air and sunlight, deposit their dissolved matter to form limestones.

Containing calcium or calcium carbonate; chalky.
