Ecological Role

Forms the foundational continental crust and weathering granite creates mineral-rich soils and sandy sediments.

Easily Confused With

Gneiss or quartz-rich pegmatites; distinguished by gneiss having a foliated banded texture rather than random interlocking crystals.

Observation Tips

Look in mountainous regions, riverbeds, road cuts, or building facades where natural stone is used.

Interesting Facts

Granite is the most common rock of Earth's continental crust and is exceptionally durable, making it a popular building and monument material.
