Abstract

Desert varnish coatings rich in manganese are reported, to the authors knowledge , for the first time on desert rocks from Australia. Varnish was found on chert, dolomite, sandstone, siltstone, and conglomerate rocks in stony pave men Is of the Gibson Desert and the Great Victoria Desert of Western Australia and South Australia. The widespread occurrence of desert pavements in Australia suggests that desert varnish, also, may be widespread. Fungi that form microcolonies have been found on rocks with desert varnish. Manganese was found in higher concentrations inside some of the microcolonies than in the surrounding substrate, suggesting that microcolonial fungi are involved in the formation of desert rock varnish in these areas.
