Enigma of the desert.

Research output: Contribution to journalArticle

Abstract

Desert varnish is a thin coating of manganese, iron, clays and trace elements on rock surfaces, best developed on the oldest and most stable of those surfaces. A surface microbial community performs the crucial task of concentrating the manganese in the process of varnish formation which may take up to 10 000 years. A technique is now being developed to accurately date the ages of samples of varnish (by examining the ratio of leachable to non-leachable elements), opening the way for studies on past atmospheric conditions, desert landforms and anthropology. - N.Pinder
