    The document discusses eolian (wind-related) environments and systems. It describes different types of dune formations and classifications of eolian systems. Eolian sandstones make good reservoir rocks for hydrocarbons due to their coarse-grained and well-sorted nature, though they require an external source of hydrocarbons. Eolian environments typically have low to moderate ichnodiversity and trace fossil assemblages dominated by locomotion traces along with some habitation and feeding structures made by invertebrates like arthropods and vertebrate tracks.

    ENVIRONMENTS OF ORGANIC
    MATTER ACCUMULATION
    DESERTS (< 0.05% OM)

    • Waxy organic matter


    • Almost all converted to CO2 and H2O
    • Almost no source-rock potential (but
    sandstones in deserts may have high
    reservoir potential)
    EOLIAN RESERVOIRS

    • Eolian sandstones are coarse-grained


    and extremely well sorted, so form
    good reservoir rocks.
    • They need an external source of
    hydrocarbons to become a reservoir.
    • Evaporites may form caprocks.
    AMBIENTES EOLICOS
    • Icnodiversidad y densidad baja o
    raramente moderada
    • Dominio de trazas de locomoción, con
    presencia subordinada de estructuras de
    habitación y alimentación
    • Asociación de trazas de invertebrados
    (mayormente artrópodos) con huellas de
    vertebrados
