Figure 4-3. Vertical stylolite (large black arrow) in a Mississippian micstone to packstone. Vertical stylolites are commonly intepreted to have result from tectonic compression, and the location of this sample just west of the limit of Appalachian folding and thrusting shows that tectonic styloites can form in regions beyond larger-scale deformation. For more details, see Railsback and Andrews (1995). The larger stylolite here has partly consumed a smaller one (small black arrow).
