Cathodoluminescent zonation in shallow burial calcite cements of the Keyser and New Creek Limestones (lower Helderberg Group, Upper Silurian-Lower Devonian) in Virginia, West Virginia, and Maryland can be mapped regionally. Regional distribution of cement zones coincides with the distribution of easterly derived sandstone tongues within the carbonate sequence. This study emphasizes the importance of (1) tectonic uplands as recharge areas for aquifers involved in cementation; (2) potential of interlayered sandstones in carbonate sequences to act as permeable conduits for meteoric ground waters because they are less susceptible to calcite cementation than associated lime grainstones; and (3) documenting regional cathodoluminescent zonation of porosity-occluding shallow burial calcite cements in potential reservoir facies prior to hydrocarbon migration.
