This beach landform is quite common in Western Europe, because the pebbles come from the lines of flint in the chalk. Chesil Bank is an example. When the chalk erodes, the tough flint stays as pebbles.
On the east coast of New Zealand's South Island, there are mixed shingle and sand fans amongst braided rivers. The ecosystems formed by this mix of pebbles and sand allow colonization by rare and endangered species.
