Abstract

Extensive bedding-parallel cement and sediment-filled voids occur in peritidal carbonate sediments of the Upper Jurassic, St. Croix Formation of the Calcaires Blanc de Provence, southeast France. Sheet voids are present in both grainstones and in stromatolitic sediments and are formed by different processes in each lithology. The best-developed sheet voids occur in fenestral grainstones, often between layers of different grain size, where they are up to a meter long and 5mm high. In contrast to previously-described examples of bedding-parallel voids in peritidal carbonates, these sheet voids are not linked to vertical desiccation cracks nor are they linked to separation of layers during tepee formation. Sheet voids described here were formed by winnowing/erosion of unconsolidated or lightly-cemented sediment from between early-cemented grainstone layers deposited in a beach and very shallow subtidal environmnent. Erosion and winnowing were probably initiated in the swash zone, and may have continued in the subtidal, together with some sediment deposition in parts of the voids. The dominant fill is vadose/phreatic marine radiaxial fibrous calcite cement, the first-reported occurrence of this type of cement in beachrock. Remaining pore space is occluded by probable meteoric phreatic cements which were precipitated during later subaerial exposure associated with extensive pedogenesis of the overlying carbonate mud-dominated succession. Examples of ancient beachrock sediments are not common, and we suggest that sheet cements of this type may be diagnostic.
