SECTION 6. LAMINATED POLAR TERRAIN AND OTHER
AEOLIAN-RELATED FEATURES
20. Polar Laminated Terrain

Polar laminated terrain (PLT) has been observed at both poles when exposed by the retreat of the seasonal ice cap. The layering is thought to be visible because of a varying dust/volatile composition between the layers. Polar laminated terrain is an aeolian deposit, exposed by wind erosion.
