Ecological Role
Rocks and pebbles provide substrate for lichens and mosses, contribute to soil formation as they weather, and create microhabitats for small invertebrates.
Easily Confused With
Other intrusive igneous rocks like diorite or gneiss, distinguished by mineral grain size and compositional banding in metamorphic rocks.
Observation Tips
Look along riverbanks and gravel bars where water action exposes a variety of smooth, rounded stones.
Interesting Facts
