Lithological description The Mons limestone is a pale, marine limestone, friable or sometimes very coherent; it contains a very abundant neritic macrofauna. An erosional surface separates the Mons Fm from the Spiennes Chalk in the borehole of the stratotype. A clear superposition of the Mons limestone on the sediments of the Ciply Fm has never been demonstrated.
Age Middle and Late Danian.
Thickness Strongly fluctuating, from 15 to nearly 70 m.
Area of occurrence The central part of the Mons Basin, only in boreholes.
Type locality “Goffint” pit at Mons (cf. Cornet & Briart, 1865), “Coppée” pit at Mons (cf. Cornet & Briart, 1865; Robaszynski, 1981). Mons borehole (cf. Marlière, 1977). Sheet 45/7-8 (Mons – Givry). Co-ordinates: x = 123.10, y = 128.14, z = +56.8 m.
