    Lithology
    The Alge Member forms the lower high gamma intensity part of the Hekkingen Formation and consists of black paper shales rich in organic material.
    Lower boundary definition
    The base is defined by the transition from carbonate cemented and pyritic mudstones to poorly consolidated shales, producing a sudden increase in interval transit time and an abrupt decrease in bulk density values.
    Age
    Late Oxfordian – Kimmeridgian, based on ammonites and palynology.
    Depositional environment
    The member was deposited in restricted shelf environments.
