Figure A-7. Wackestone (a micritic limestone) from the Ordovician of central Tennessee. The right side of the image shows relatively uniform micrite; the left side of the image shows micrite in which small peloids (e.g., at arrows) are present. Also present is the calcite-filled mold (M) of a skeletal grain, probably a fragment of a mollusc shell.
   Photomicrograph was taken in plane-polarized light; field of view is 2.4 mm wide. U.S. 70S roadcut west of Woodbury, Tennessee, U.S.A; thin section ME6A1-3. Sample collected by L. Bruce Railsback.
