Insoluble residues are valuable for correlation in that they contain detrital and authigenic minerals and structures such as dolocasts. Acetic acid is shown to give a more satisfactory residue from limestone than hydrochloric acid, in that it preserves a more complete mineral suite; leaves a support for the frail silica cast; and provides a clean residue, without forming a gel, flocculated clay or organic coating. Some results are given of work with Upper Silurian limestones from Syracuse, New York.
