Definition The Z2 Carbonate Member in the centre of the basin is developed as a thin, finely laminated, argillaceous, black and often bituminous limestone, designated in Dutch literature as the Stinking Shale Visser (1963) after the German ‘Stinkschiefer’. On the slope of the basin the member is developed as a thicker-bedded limestone, the Fetid Limestone or ‘Stinkkalk’. Along the basin margin, this member usually consists of a massive to thick-bedded, light-coloured, sometimes oolitic or bioclastic dolomite, with intercalations of anhydrite. This typical facies is called Main Dolomite (Brueren (1959) ; Visser (1963) ). Towards the fringe area this unit’s lateral equivalents are anhydrite and claystone. On wire-line logs the Z2 Carbonate Member is characterized by an increasing amount of clay towards the top. Enormous thicknesses of this unit are recorded in southeast Drenthe (van Wijhe, 1981). The Z2 Carbonate Member has a more limited southward range than the Z1 and Z3 Carbonate Members (van Adrichem Boogaert and Burgers, 1983; Plomp and Geluk, 1988).
