AB Black shales from Carai (Vizcaya) have been studied from the following points of view: mineralogy, geochemistry (pyrolysis rock-eval), porosimetry measurements and clay fabric. Data obtained suggest that: a) The presen ce of organic matter exerts a secondary influence in con trolling porosity and clay fabric, b) A significant percentage of carbonate minerals inhibit clay particle orientation, c) There is little or no connection between porosity and/or fabric and clay mineral composition, except perphaps in sediments with appreciable mixed-layers l-S content, d) There seems to be no relationship between porosity and/or fabric and total clay content, e) Compaction processes are not the main control on the structural properties of these rocks
