Containing or producing calcium or lime; bearing or generating calcareous matter.
From Latin 'calcis' (lime/calcium) + '-ferous' (bearing or carrying). The term emerged in scientific contexts to describe minerals and rocks that contain significant calcium compounds, particularly in geology and biology during the 18th-19th centuries.
Calciferous rocks like limestone literally built the White Cliffs of Dover and much of Earth's seafloor—trillions of tiny shells and skeletons compressed into stone over millions of years. It's the reason some soils are perfect for growing certain plants but terrible for others.
