Geochemistry of Ni in the Cretaceous-Tertiary succession Fiskeler (Fish Clay) at Stevns Klint (Denmark): cheto-smectite of the black marl [PDF]
Journal of the Serbian Chemical Society, 2006 The Cretaceus-Tertiary (KT) boundary at Stevns Klint (the Højerup succession), Fiskeler, consists of a thin red clay layer overlain by a thick one of black marl. These two layers are made up mainly from cheto-smectite and biogenic calcite. The black marl

Polymer‐clay nanocomposite hydrogels with multiple responses to multiple stimuli
Responsive MaterialsHydrogels are widely studied for their stimuli‐responsive properties. They adapt to external stimuli, including physical, chemical and biological ones. To enhance adaptability in complex environments, multi‐responsive hydrogels have been developed, which

Using [delta] ph as a geochemical index of illite neoformation in saprolite [PDF]
, 2008 Sal pH is routinely measured for agronomic purposes. When the difference between KCI pH and H2O pH, or ApH, yields positive values, it is used by soil scientists as a classification criterion for identifying anionic subgroups according to the Soil ...

Impact contribution of prebiotic reactants to Earth [PDF]
It is proposed that the AIB amino acid at the K/T boundary were synthesized during entry of a comet. However, whether they were synthesized or supplied directly from space, the concentration of amino acids in the shallow K/T sea would have been about 10 ...

Geologica Acta, 2009 The black marl of the Fish Clay at Højerup is mainly made up of biogenic calcite and cheto-Mg-smectite. We suggest that the formation of the smectite occurred during the latest Maastrichtian (or earlier) and that it represents a short period of rapid ...
