(17) Manlius limestone. Lime mud rock, fine textured, dense, with plainly marked sedimentation lines, gray to dark gray color. The most characteristic features in the field are (a) fine texture, (b) sedimentation lines, as if laid down in quiet waters as a lime mud, (c) solution joints sometimes enlarged to.
