Definition

Sand-covered area with a featureless, low-relief surface and without superimposed individual dunes or high-order bedforms.

A type of aeolian sand deposits.

Description

Featureless, nearly horizontally stratified continuous deposits (Grotzinger et al. 2005) of windblown fine-grained particles with low thermal inertia. Their surface may be smooth and nearly featureless, but there are often tabular-planar depositional features and various ripple-like bedforms observed (Breed et al. 1987). Sand sheets range from 100 s m2 to 100,000 m2 on Earth. Thickness can range from several centimeters to 10s m (Pye and Tsoar 1990).

Subtypes

  1. 1.

    Sand sheet: sheetlike sand blankets with broad, flat surface and distinct geographic boundaries. Their sand is poorly sorted (Pye and Tsoar 1990) and often shows a bimodal grain size population (silt, fine sand or poorly sorted coarse sand). They may contain ripples and zibars and are usually peripheral to major dune areas but occasionally adjoin them.
