An angular disconformity is characterized by a gap in the geological record where younger sedimentary layers are deposited on top of older, tilted or folded layers. The older layers are often at an angle to the horizontal younger layers, indicating a period of erosion or tectonic activity before the deposition of the newer strata. Visually, this can appear as a distinct boundary between the two sets of rock layers, with the angular relationships highlighting the history of geological events in that area.
