Graphic Correlation - An increasing number of geologists have begun to use graphic correlation because they find this robust technique provides finer stratigraphic resolution and better accuracy and precision than traditional zonations. This volume presents the graphic correlation method, recent methodological developments, and a number of technical papers exemplifying the technique. This collection of papers presents a summary of the technique as currently practiced and it should provide a starting point for those interested in high resolution stratigraphy through graphic correlation. Graphic correlation continues to develop and spread as more geologists use this important and innovative technique. Its potential is only beginning to become realized.

Middle Ordovician graplolite-rich shales exposed in the southern Appalachians provide an opportunity to apply graphic correlation to what appear to be inadequate data. The fact that the resulting composite standard (CS) is used successfully to address significant geologic problems demonstrates the effectiveness and versatility of the technique. The shales are so strongly diachronous that no single stratigraphic section spans the entire biostratigraphic interval represenled by the shales. The Standard Reference Section (SRS) included only a part of this interval. Therefore, many partially overlapping sections had to be used in the construction of the CS with each section extending the...
