A sequence of sedimentary layers stacked one atop the other is known as a stratigraphic section. ... These layers make up the geological timescale section known as the Chinle Formation, which was ...Unconformities. Unconformities are ancient surfaces of erosion and/or non-deposition that indicate a gap or hiatus in the stratigraphic record. An unconformity may be represented on a map by a different type of line from that used for other geological contacts; in a cross-section an unconformity is often shown by a wavy or crenulated line.
