Figure 5-6. Two large horizontal stylolites in an Ordovician oolitic grainstone. The upper stylolite is cut by and so predates a calcite-filled fracture (C), whereas the lower stylolites cuts and so postdates the fractures. The earlier (upper) stylolite is more serrate, which Andrews and Railsback (1997) found to be typical of early-formed stylolites.
