Why Are Loess Sediments Important
Loess is one of the most extensive surficial geologic deposits in midcontinental North America, particularly in the central Great Plains region of Nebraska. Last-glacial-age loess (Peoria Loess) reaches its greatest known thickness in the world in this area.

What are the loess plains?

Loess is an aeolian sediment produced by wind-blown silt deposition, usually in the size range of 20-50 micrometres, twenty percent or less clay and the equilibrium of sand and silt components that are loosely cemented by calcium carbonate. Therefore, the loess plains are flat regions covered by such deposits.

How are loess formed 7?

Explanation: Loess is a fine silted soil formed by the deposition of dust brought by the action of winds. It can be very fertile under favourable climatic conditions.
