Terrestrial sediments are difficult to correlate because they are laterally variable and generally lack easily identifiable chronostratigraphic surfaces. However, we have been able to identify systematic variations in petrographic properties of paralic coal that respond to changes in accommodation. These properties enable us to distinguish two types of paralic peat cycle (transgressive and regressive) characterized by wetting-upward and drying-upward behavior linked to variations in the groundwater table. They also enable recognition of a range of terrestrial stratigraphic surfaces that record responses to changing accommodation, including accommodation reversal surfaces, flooding surfaces, hiatal surfaces, paludification surfaces, and terrestrialization surfaces. A combination...
