Macroscopic observations of the calcite veins. (a) Group I vein generation characterized by a network of pseudo parallel thin veins. (b) A vein from Group I crosscut and displaced by a compaction stylolite. (c) Hydraulic breccia and its typical jigsaw texture. (d) Hydraulic breccia crosscutting the stratigraphic section and compaction stylolites. (e) Hydraulic breccia (with Group II veins) intruded by Group III vein (bright white color). (f) Group III vein crosscutting compactional stylolites. (g) Large calcite crystals infilling porosity along the main fault plane (Group III veins).
