| Abbreviation | KoZo |
| Parent unit | Kortrijk Formation |
| Child units | |
| Lithological description | Silty to sandy clay, bioturbated and with irregular pockets and lenses of very fine silty sand. Fine grained mica, woody debris and glauconite are present in sieve residues throughout the unit (King, 1990). Coarse grained angular to subangular grains are identified as degraded volcanic ash. Pebbles occur in the base of the overlying clay. |

| Area of occurrence | The Zoute Member is a thin unit of almost 5 m thickness found at the base of the Ieper Group section in the Knokke borehole (011E0138) at the Zoute hamlet and first described in detail by King (1990, p70) and at that time named Member X by this author. The name Het Zoute Member was proposed by Steurbaut (1998, p110). It was erroneously interpreted as Mont? Héribu Member by Geets & De Geyter (1990, p25). This unit has no equivalent in other sections of the Ieper Group in Belgium where it corresponds to a hiatus between the Landen and Ieper Groups; this is confirmed in Steurbaut (2006, p77). |

| Additional information | The indication of volcanic activity is a particular property of this unit. The other indication of volcanic grains in the basal sediments of the Ieper Group clays are the heavy mineral types in the basal clays, identified as Mont?Héribu as reported by Geets (1993). This volcanic activity is related to the ash series at base of the Eocene in the North Sea Basin and correlates to the A1 Division of the London Clay Formation (King, 1990, p 80). |
