⛏ Angadipuram Laterite

Laterite is a rock type found in the tropical region. The term laterite was coined by Francis Buchanan-Hamilton in 1807 based on his observations on the rock type found near Angadipuram, Malappuram district, Kerala. It is a type of secondary residual product resulting from the chemical weathering of varied rock types. It is economically significant for its mineral deposits and is also used as bricks in construction. Angadipuram Laterite was declared as a National Geological Monument by the Geological Survey of India in 1979.
