Chronostratigraphic units are bodies of rocks, layered or unlayered, that were formed during a specified interval of geologic time. The units of geologic time during which chronostratigraphic units were formed are called geochronologic units. The relation of chronostratigraphic units to other kinds of stratigraphic units is discussed in Chapter Chronostratigraphy The element of stratigraphy that deals with the relative time relations and ages of rock bodies. Chronostratigraphic classification The organization of rocks into units on the basis of their age or time of origin. Chronostratigraphic unit A body of rocks that includes all rocks formed during a specific interval of geologic time, and only those rocks formed during that time span.
