Figure 2-9. Rhombs of dolomite (red Ds) concentrated in the residue at of a stylolite in a bioclastic grainstone containing echinoderm fragements (E) and bryozoan pieces (B). The relative scarcity of dolomite rhombs in the host rock (small red arrow) suggests that much rock has been consumed or that the stylolite formed in a dolomite-rich zone.

      Photomicrograph was taken in plane-polarized light; field of view is 2.4 mm wide. Lebanon, Tennessee; Sample ME11-1; thin section ME11-1. Sample collected by L. Bruce Railsback.
