An ecophysiological explanation for manganese enrichment in rock varnish
Desert varnish is a dark rock coating that forms in arid environments worldwide. It is highly
and selectively enriched in manganese, the mechanism for which has been a long-standing …

Geochemical insights into the relationship of rock varnish and adjacent mineral dust fractions
Rock varnishes are μm-thin, dark, manganese (Mn)-rich crusts that accrete in the order of
few μm/ka on weathering-resistant lithologies. Although these crusts can form in all climates …
