Title: Criteria for Subsurface Recognition of Unconformities

Author(s): W. C. Krumbein (2)

Abstract:

Criteria which have been advanced as evidences of unconformities are summarized and discussed in terms of their application to subsurface studies. These criteria are classified as sedimentary, paleontologic, and structural; approximately 40 are considered. It is emphasized that certain limitations must be imposed on the criteria, but that the convergence of several lines of evidence may strongly suggest the presence of stratigraphic breaks. Extensions of this reasoning to the possible development of new criteria are pointed out.
