Figure F10. Comparison of downhole variation diagrams of the ratios of siliciclastic and volcaniclastic framework grains: total detrital cbnte: carbonaceous detritus: cement: matrix, for all the northern sites (see Table T1, , for further information). Total detrital cbnte = carbonate skeletal (e.g., foraminifers, shell fragments, red algae, bryozoans, etc.) + carbonate aggre (detital carbonate aggregates), Carb = carbonaceous fragments (plant debris), M = matrix, C = cement.
