Definition von desert varnish im Englisch Englisch wörterbuch

or patina Thin, dark red to black mineral coating (generally iron and manganese oxides and silica) deposited on pebbles and rocks on the surface of desert regions. As dew and soil moisture brought to the surface by capillary action evaporate, their dissolved minerals are deposited on the surface. Wind abrasion removes the softer salts and polishes the surface to a glossy finish. Both high evaporation rates and sufficient precipitation are necessary for desert varnish to form

thin and shiny layer that is reddish brown or black in color composed of iron and manganese oxides which coats the surfaces of many desert rocks that are exposed
