Figure Caption    Varnish microstratigraphies from (A) Patagonia Desert, Argentina; (B) Gürbantongüt Desert, western China; (C) Negev Desert, Israel; and (D) Mojave Desert, western USA. These samples were collected from various geomorphic surfaces of latest Pleistocene age (i.e., 11500-18000 cal yr BP). Maximum varnish thicknesses (in µm) are 80 (A), 45 (B), 100 (C), 120 (D).
