This field guide gives an insight into the Lower Palaeozoic geology of the Geete outcrop area in the surroundings of Jodoigne. Five selected outcrops or groups of outcrops are visited. These are the northern Dongelberg Quarry at Dongelberg, the Les Fosses Quarry at Opprebais (Incourt), outcrops along the Rue du Maka at Jauchelette, outcrops along the Rue du Vieux Moulin at Jodoigne and the outcrop below the town hall at Jodoigne. In each case, a detailed description is provided of the lithology, lithostratigraphy and structural architecture, followed by remarks and interpretation. The geological observations from these field trip stops are used to illustrate lithological differences between the Blanmont Formation and the different facies of the Jodoigne Formation, to demonstrate the presence of steeply plunging and gently plunging folds, to illustrate the common occurrence of pre-cleavage folds, interpreted as slump folds, and to outline our arguments for the newly proposed stratigraphic position of the Jodoigne Formation. The cartographic proximity of the Lower Cambrian Blanmont Formation and the Middle to Upper Cambrian Jodoigne Formation is explained by means of the Asquempont Detachment System.

The observations and their implications are placed in the broader context of the Belgian Lower Palaeozoic.
