Loess – the Earth’s most fragile rock!
Loess is formed from fine (small) grained, windblown sediment in glacier or desert areas. Loess is made of mostly silt but may also have some small amounts of sand and clay. The major mineral present is quartz with minor amounts of feldspar, calcite, dolomite, and clay.
