Physical properties
Hardness varies from 3 to 7 depending on iron content, reddish-brown to yellowish-orange color, dull luster, porous or pisolitic structure, with poor cleavage and high specific gravity.
Formation & geological history
Formed through intense and prolonged tropical weathering of parent rocks under alternating wet and dry conditions.
Uses & applications
Used primarily as a building material (cut into brick-like blocks), road aggregate, and as a source ore for aluminum and iron.
Geological facts
Laterite develops extensively in tropical regions and hardens irreversibly upon exposure to air, making it a durable historical building stone.
Field identification & locations
Easily identified by its distinct rusty red color, porous texture, and mottled appearance. Common in tropical and subtropical regions.
