👉 Stonage is a type of rock formation formed by erosion and weathering processes. It is composed of large, compact pieces of sedimentary rock that are often found in areas with high levels of rainfall or melting ice. The stones can range from small pebbles to large boulders, and they may be found on the surface or buried deep underground. Stonage can vary greatly in size and shape, and it is an important part of many coastal and mountain landscapes around the world.
