Eocene clay called Søvind Marl. Seven samples are tested; with additional data from further four tests. All samples originate from the Søvind Marl formation at Aarhus, Denmark, which in deposit history, structure and characteristic resembles London Clay. The undrained shear strengths are normalised using SHANSEP (Ladd et al. 1977) and compared to measured field vane shear strength, c fv (kPa ...

 · We developed a novel dry crushing method that isolates microaggregates along failure planes due to mechanical stresses rather than hydraulic pressures and compared the mechanical stability, OC contents and microbial community composition between drycrushed and wetsieved samples with contrasting clay contents. Drycrushed samples exhibited a higher stability and bacterial .

These marls are silty clays (70–88% of 2–20 µm fraction) with medium plasticity, and they are suitable for clay roofing tiles and structural clay products (El Ouahabi et al., Reference El Ouahabi, Daoudi and Fagel 2014b). In central northern Morocco (Meknes region), Miocene homogeneous yellow sandy marls are present in the Saïs Basin, consisting of clay minerals (27–45%), quartz (19 ...

The texture of 'blowaway' sandy soils and Black Fen soils can be improved by applying 400–750 t/hectare of clay or marl (a limerich clay). If the subsoil of the area is clay, it can be dug out of trenches and roughly stered by a dragline excavator. In other cases, the clay is dug in pits and transported in special lorry spreaders. Rotary cultivators help to spread the clay. If the ...

 · Marl is usually though of as an impure chalk with a much higher content of clay and silt grains. The marls in the Alabama Coastal Plain, for example, are usually about onethird pelagic carbonate, onethird clay, and onethird silt (quartz and feldspars, mainly). Chalk is oceanic, whereas marl may be oceanic or lacustrine. Chalk is most common in the Cretaceous System, whereas marl has no ...
