WebAn angular unconformity is an unconformity in which the strata above and below have different trends in their dip i.e the dip in different directions. As shown in the figure, the layers M and G dip at different angles from each other and hence the unconformity between them is an angular unconformity. WebNov 2, 2024 · Such a formation is called an unconformity, or a gap in rock layers, where some rocks were eroded away. Hutton reconstructed the sequence of events that led to this formation.
