Graphic Correlation

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.
High-Resolution Biostratigraphy in the Upper Cambrian Ore Hill Member of the Gatesburg Formation, South-Central Pennsylvania

Abstract
Microstratigraphic sampling of four measured sections in the Upper Cambrian Ore Hill Member of the Gatesburg Formation in south-central Pennsylvania produced a data set adequate for construction of ‘a composite standard superior to the composite range chart previously erected by Wilson (1951) for trilobite faunas of that unit. This new data set revealed the presence of two thin, widespread units not previously reponed from the central Appalachians: the Irvingella major Subzone al the top of the Elvina Zone and the Parabolinoides Subzone at the base of the Taenicephalus Zone. A new subzone, the Cliffia lataegenae Subzone, is proposed to...
