Geological Unconformities: What Are They and How Much Time Do They Represent?
Fig. 1
What are unconformities and what do they mean to young-earth, biblical creationists? The simple definition is that they are surfaces, usually seen as a linear contact in a vertical rock outcrop or exposure, that separate younger overlying rock strata or layers from the older strata below. They are interpreted by uniformitarian (evolutionist and “old-earth creationist”) geologists as gaps in the record, each gap representing missing time and sediments. But is this interpretation warranted by the field evidence?
