Physical properties
Hardness of 3 on the Mohs scale, tan to brown color, dull to earthy luster, and reacts strongly with hydrochloric acid.
Formation & geological history
Formed through the accumulation of organic debris and chemical precipitation in shallow marine environments over millions of years.
Uses & applications
Used primarily in construction, cement production, agriculture, and as a raw material for lime.
Geological facts
Vugs form when groundwater dissolves portions of the rock, leaving hollow cavities that often line with secondary mineral crystals.
Field identification & locations
Identify by its brownish hue, porous or cavernous texture, and characteristic fizz when tested with acid.
