Tan Brown Granite

Physical Properties

Hardness: 6-7 on Mohs scale. Color: Dark brown base with tan, reddish-brown, and black flecks. Luster: Vitreous when polished. Structure: Coarse-grained (phaneritic) crystalline structure. High specific gravity.

Formation & Geological History

Formed through the slow cooling and crystallization of molten magma deep within the Earth's crust (plutonic formation). These commercial varieties are typically Precambrian in age, often sourced from the Indian Shield (southern India).

Uses & Applications

Predominantly used for kitchen countertops, flooring, wall cladding, and exterior monument construction due to its durability and resistance to weathering.

Geological Facts

Commercial 'granite' like Tan Brown often contains large concentrations of orthoclase feldspar, which gives it the distinct tan crystals. It is one of the most popular granite choices globally because of its consistent pattern and stain resistance.

Field Identification & Locations

Identify by its interlocking coarse crystals and distinctive three-tone color palette (black, dark brown, and tan). It resists scratching from steel and does not react to acidic liquids like vinegar, distinguishing it from marble.
