Lithological description
Contains all loess units characterised essentially by silt size (mostly 16-62µm), an allochtonous mineralogy, a clay fraction originally ca. 10% but increasing to ca. 30% by weathering (clay illuviation in interglacial Luvisols).
Age
Middle and Upper Pleistocene.
Thickness
Area of occurrence
Middle Belgium, on plateau and slopes.
Type locality
Eben-Emael (CBR chalk quarry at Romont). The western (50°47’27”N / 5°38’37”E) and eastern (50°47’08”N / 5°39’27”E) walls of the quarry, corresponding to the limits of the exploitation, will be accessible in the long run. They are exposing both formations of the Romont Group easy of access on top of the fluviatile deposits of the Romont Terrace (Juvigné et al., 2008).
