title = "Geochemical properties of the marine Younger Miocene at Gram, SW Jutland",
abstract = "The marine Younger Miocene at Gram, SW Jutland , has been examined chemically. The Hodde Clay may be subdivided on the basis of a high, but varying content of organic matter. In the Gram Clay, carbonate, manganese and phosphorus are enriched in beds with clay ironstone concretions. The composition of the sand fraction indicates that the sequence has been subject to diagenetic processes. The Hodde Clay may have been deposited in an estuarine environment with a periodically strong sedimentation of allochthonous terrestrial humic matter. The Glauconite Clay and the basal goethite-rich bed of the Gram Clay indicate an agitated and oxygenated environment, which changes to less agitated and more marine conditions during deposition of the Gram Clay.",
