Approximately 10% original black shale preserved. Secondary diagenetic calcite. Glauconite is concentrated in some areas. Two big pebbles of phosphate (total area)."

207	1261	B	7	R	5	100	102	584.98	116	D		25	30			2					*			10			*	*				33								100	Foraminifer wackestone	Fabric is disturbed by calcite recrystallization. Micrite is in patches and background matrix. Microspar-size diagenetic calcite. Trace of Inoceramus shell fragments.
207	1261	B	11	R	1	26	30	616.66	117	D		30				2					2			22								40				4				100	Clayey chalk with foraminifer wackestone	Micrites are background micrite to microsparite. Foraminifers are recrystallized.
207	1261	B	12	R	4	85	88	631.3	118			41						25														10	12			12			*	100	Phosphoritic claystone with foraminifers and organic matter	One large phosphate nodule with big fish fragments in typical black shale. Layers with fish debris. One long Inoceramus shell. Fish remains are mainly counted as phosphorite. Foraminifers are counted as sparite.
207	1261	B	14	R	CC	2	3	650.36	119	D					*		46														5			1	44		2	2		100	Quartz arenite with calcite cement	Quartz is angular to subrounded. Cement is large drusy calcite. Clasts are lithic fragments.

Other mineral: unknown very dark, but not opaque, mineralÐFe-oxide coating(?). Thin section also includes echinoid fragments and other ""shell material""."
