Fluvial deposition is quite extensive near the margin of glaciers. Because the melting ice provides considerable runoff, the abraded material from the glacier will be transported and deposited. Such features include thick sand and gravel deposits closer to the glacier margin and more fine-grained rock-flour deposits (silt and clay) further downstream. Because of the high rate of deposition, these deposits are often buried in an outwash plain.
Fluvio-glacial features include outwash plains, valley trains, and braided streams.
