About this subject

Granite is a plutonic igneous rock formed by the slow cooling of magma deep within the Earth's crust. Its phaneritic texture, with visible crystals of quartz, feldspar, and mica, gives it characteristic strength and beauty. Massive granite mountains, such as Sugarloaf in Rio de Janeiro and Mount Rushmore in the USA, are iconic for their grandeur and geological durability. Granite resists erosion better than most rocks, creating dramatic landscapes and isolated peaks. In Brazil, the Serra do Mar and Chapada Diamantina have granite outcrops that attract tourists and climbers. Culturally, these formations were used by indigenous peoples for rituals and later as quarries for historic masonry. Granite extraction for construction is a global industry, with Brazil being one of the world's largest producers of dimension stone.
