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.
Graphic Assembly of a Conodont-Based Composite Standard for the Ordovician System of North America

Published:January 01, 1995
Abstract
A composite standard (CS), assembled graphically through consideration of the ranges of more than 300 conodont species in measured sections at 127 localities, will apparently be adequate as the backbone for a conodont-based chronostratigraphic framework for the Ordovician System of North America. The SRS is a 374-m core through Middle and Upper Ordovician rocks drilled at a site in north-central Kentucky. Relations between the SRS and additional Ordovician sections have been determined graphically following a compilation strategy that involves extension of the network of correlated sections into older and younger rocks by use of overlapping control sections. The weakest...
