Patterns of Porosity and Cement in Ooid Reservoirs in Dogger (Middle Jurassic) of France: Discussion¹ Available to Purchase

The interpretation made by Cussey and Friedman (1977) that the textures of the tightly compacted oolites of the Jurassic of the Paris basin were due to pressure solution is clearly incompatible with their description of the sediments. In a photomicrograph of an example of one of the compacted oolites (Fig. 4, Cussey and Friedman, 1977), there is very little actual contact between the grains and cement is present around virtually the entire circumferences of all the grains. If pressure-solution had occurred it is very unlikely that the cement would have been preserved in such a way, for the grains...
