An unconformity is a buried erosional or non-depositional surface separating two rock masses or strata of different ages, indicating that sediment deposition was not continuous. In general, the older layer was exposed to erosion for an interval of time before deposition of the younger layer, but the term is used to describe any break in the ...
Cross-cutting relationships can be used to determine the relative ages of rock strata and other structures. Explanations: A – folded rock strata cut by a thrust fault; B – large intrusion (cutting through A); C – erosional angular unconformity (cutting off A & B) on which rock strata were deposited; D – volcanic dike (cutting through A, B & C); E – even younger rock strata (overlying ...
In geology, a subaerial unconformity is a surface that displays signs of erosion by processes that commonly occur on the surface. [1] These processes generating the subaerial unconformity can include wind degradation, pedogenesis, dissolution processes such as karstification as well as fluvial processes such as fluvial erosion, bypass and river rejuvenation.
Tirupati Eparchaean Unconformity, a notified National Geo-heritage Monument [1] [2] [3] is a major discontinuity of stratigraphic significance that represents a period of remarkable serenity in the geological history of the Earth i.e. sudden changes and discontinuity in the rock layers in Earth's crust.
Hutton Unconformity at Inchbonny, Jedburgh. A photograph shows the current scene (2003), below Clerk of Eldin's illustration of 1787; N 55.4721, W 2.5545. On a trip to the Isle of Arran in 1787 he found his first example of an unconformity to the north of Newton Point near Lochranza, but the limited view did not give the information he needed.

When ensuring quality of a product or a service, classification of a nonconformity is important, as it provides an opportunity to better reduce nonconformity. [1] Many quality management practices will do this using a relatively simple three- or four-level classification system.
