Resumen

Palynomorph percentages of modern surface samples (%) and palynomorph percentages (%) and total concentrations (palynomorphs per gram of dry sediment) from three paleosols (Ps6, Ps7, and Ps8) that developed in the upper part of the Arturo perched dune deposits, in the periphery of the homonymous lake, Fuegian steppe, southern Argentina.

Métodos

Surface and fossil sediment palynological samples were sieved through a 150 'm mesh screen and treated with 10% HCl and 70% HF acids in order to remove carbonates and silica, respectively. Two Lycopodium clavatum tablets were added to each sample prior to the treatment for the calculation of the palynomorph concentration per gram of dry sediment (Stockmarr, 1971). Organic residues were sieved through a 10 'm nylon mesh and stained with Safranin-O (Stanley, 1966). Permanent slides were mounted with glycerine-gelatin and examined using transmitted light microscopy at 400 and 1000× magnification. Modern and fossil palynological slides were stored in the Laboratorio de Palinología at Universidad Nacional del Sur (Bahía Blanca, Argentina) and coded as UNSP followed by the denomination of the sampling site: MS (Muestra Superficial) and PDA (Paleosuelo Duna Arturo).
