The 14 pages that link to Unconformity, each with the reason it gives.

• Grand CanyonRelated: The Great Unconformity separates ancient crystalline rocks from younger sedimentary layers.

• Relative datingBroader topic: An unconformity marks a break in the sequence that relative dating reconstructs.

• LithologyRelated: A lithologic change across an unconformity may accompany missing geological time.

• Chinle FormationRelated: Unconformities bound or interrupt parts of the Chinle regional sequence.

• ChronostratigraphyCompared with: A gap in the record can interrupt the sequence used to correlate time.

• Stratigraphic correlationRelated: Missing time can interrupt apparent layer-by-layer matches between successions.

• Jurassic CoastRelated: The coast’s visible boundaries between rock sequences make gaps in geological time tangible.

• Geologic timeRelated: Gaps in strata mean that the preserved record does not contain every interval.

• Marine regressionRelated: Subaerial erosion during regression can create a sequence boundary or other unconformity.

• Stratigraphic unitRelated: An unconformity can mark a major boundary between rock units.

• Structural basinRelated: Unconformities can truncate basin layers and record pauses or erosion during basin development.

• Cratonic sequenceBroader topic: Major unconformities bound cratonic sequences and record pauses or erosion between depositional cycles.

• Geologic recordRelated: It marks missing time caused by erosion or nondeposition.

• Stratigraphic sectionRelated: An unconformity signals missing time within an otherwise continuous-looking section.
