Unconformities Are Gaps in the Geological Record. Gaps in the geological record, like those discovered in 2005, are called unconformities because they do not conform to typical geological expectations. The concept of an unconformity arises from two of the oldest principles of geology, first stated in 1669 by Nicholas Steno:Improve geologic map compilation efficiency within distributed mapping projects with the power of location intelligence to better collect, access, and update map data.

Geologic dating is extremely imprecise. For example, although the date listed for the beginning of the Ordovician period is 485 million years ago, it is actually 485.4 with an uncertainty (plus or minus) of 1.9 million years.

Most maps that we use in our day-to-day lives are two-dimensional: they are flat and show features like roads, cities, and natural features such as lakes and rivers. Hikers and other outdoor enthusiasts may be familiar with topographical maps, which add a third dimension: elevation. To obtain a picture of ancient geography as it existed during a particular interval of geologic time, geologists plot the distribution of various kinds of rocks for a given geologic age on a map. Then, by noting the location of …
