Summary:This Tertiary clay is examined over approx 50 m thickness in all its accessible outcrops. Data on grain-size distribution and organic content are presented. In the >53 mu m fraction light and heavy minerals are optically identified. In the 2 mu m fraction kaolinite, illite, smectite, interstratified clay minerals, and chlorite were examined by DTA and quantitative XRD. The inorganic geochemical aspect was investigated on the basis of 15 analyses by XRF and AAS for 11 major elements and of AAS for the trace elements Cu, Co, Cd, Rb, Zn, Mn, Ga, V, Ni, Cr in four leaches. AAS was performed on approx 200 mg clay for Na, K, Mg, Ca in the pore water and c.e.c. The carbonate content of the clay, calcitic septaria, concretionary and layered iron sulphides, glauconite and gypsum crystals are also considered. [R.V.T.]
