calcareous
Ite chalk-textite calcium
Calcareous means containing or composed of calcium carbonate—the chalky mineral found in limestone, coral, and shells.
The term appears in geology, biology, and soil science: calcareous rock, calcareous deposits, calcareous soil.
Such soils are alkaline and affect which plants can thrive in them.
