GI 251             Event Stratigraphy                  Assignment Guidelines
Fall 2022


The three assignments will utilize actual data sets from the Upper Devonian conodont literature to
become familiar with graphic correlation and then a Middle Devonian data set to look at magnetic
susceptibility (MS) data.  For the conodont data stratigraphic columns, tables, and an excel
spreadsheet will be provided.  For the Middle Devonian the core descriptions and MS data will be
provided.


For each assignment the graphs produced and a short explanation of the procedures and logic in the
production of a line of correlation will be submitted.


Grade will be based on, but not limited to, this outline, where +/- will reflect ranges within the
grade bin.

A – exceeds expectations

Thorough and insightful explanation of data used and line of correlation produced.  Clear and
organized graphics.


B – meets expectations

Thorough explanation of data used and line of correlation produced.  Organized graphics.


C – adequate

Complete explanation of data used and line of correlation produced.  Adequate graphics.


D – submitted but incomplete

Incomplete explanation of data used and line of correlation produced.  Poor graphics.  An
assignment that demonstrates only a minimum of effort and no actual consideration of the data will
not be considered as incomplete but a submission not worthy of a university course.


F – assignment not submitted
