Sediments deposited by glacial meltwater that are sorted and layered; a major subdivision of glacial drift that includes river, lake, and marine deposits

the size-sorted deposits of glacial debris created by the torrents of water that flowed off the retreating glaciers in meltwater streams. Many stratified drift deposits were eroded and redeposited multiple times by flowing water. This repeated sorting action created porous, permeable, stratified drift deposits that often make excellent aquifers.

glaciofluvial, glaciolacustrine, or glaciomarine drift, consisting of sorted and layered material deposited by a meltwater stream or settled from suspension in a body of quiet water adjoining a glacier.

Layers of glacial sediments deposited by glacial meltwaters. Swifter waters deposited larger particles such as sand and gravel, while slower moving waters deposited finer particles such as silt and clay.
