Which of the following mineral deposits are formed by the decomposition of rocks rich in aluminium silicates?

Correct option is B

The correct answer is (b) Bauxite deposits
Explanation:
· Bauxite is the primary ore of aluminum and is formed by the weathering and decomposition of rocks rich in aluminum silicates in tropical/sub-tropical regions.
· The process involves the leaching of soluble constituents, leaving behind a mass containing aluminium oxides.
Information Booster:
· Odisha is the largest bauxite-producing state in India.
· Aluminium is used extensively in the aircraft, electrical, and packaging industries due to its strength and lightness.
Additional Knowledge:
· Manganese: Used primarily in the manufacture of steel and ferromanganese alloys.
· Limestone: Found in sedimentary rocks; used as a basic raw material for the cement industry.
