Stylolithes

The compaction pulls a pressure of dissolution between particles silicatées and the carbonated particles. The dissolution engenders movies silicatés (clay essentially) called stylolithes. The stylolitisation is made only under a load lithostatique (and thus a depth) significant. The structure flaser (flamed) result also partially from the pressure of dissolution. A reduction of the porosity accompanies these structures.
