Lithological description In the Poppel-Mol Rauw Fault zone and east of it a coarsening downwards interval is observed below or in the base of (?) the fine-grained Retie Member. It is situated between the levels 1-2 in Vandenberghe et al. (2020) and therefore labelled informally as ‘level 1-2 sand unit’ (see also Kasterlee Formation Lithostratigraphic Information Sheet). Limited sediment information from the top of the unit in the boreholes ZEH08/05 and RUS04/03 shows this informal unit is sand, has the same colour as the Retie Member and is slightly coarser than the Retie Member. However the downwards increasing gamma-ray together with a decreasing resistivity signal as observed in the SCK13/Postel2 (032W0415 / kb17d32w-B385) logically would suggest a fining downwards.
Age See LIS file Mol Formation for information on the age of the Mol Formation units.
Thickness The thickness is about 15 m in the Postel SCK 13 borehole (032W0415 / kb17d32w-B385).
Area of occurrence The informal ‘level 1-2 sand unit’ occurs in the subsurface of Poppel-Mol Rauw Fault zone and east of it; it is limited in the east by the Reppel Fault east of which occurs the Kieseloolite Formation.
Type locality The Postel SCK 13 borehole (032W0415 / kb17d32w-B385) is suggested as a reference for the informally named ‘level 1-2 sand’ unit between 92 and 107 m.
