StrataPlot, a Graphic Correlation Tool for Biostratigraphic Analysis Emil Platon Research Assistant Professor Energy & Geoscience Institute at the University of Utah
This talk • Basic introduction to Biostratigraphy • Graphic correlation method • StrataPlot specifications • StrataPlot demonstration
Biostratigraphy • Biostratigraphy is the science of dating rocks by using the fossils contained within them. • Index Fossil - short life span -broad geographic distribution - common - easy to identify • http://en.wikipedia.org/wiki/Biostratigraphy
Biostratigraphy - Geologic Time http://www.ucmp.berkeley.edu/help/timeform.html
Biostratigraphy - Fossils • Macrofossils Ammonites (cephalopods) • very good index fossil • Microfossils Foraminifera (single-celled protists) • Planktonic species - good index fossils http://paleodirect.com/ammonites.htm

Biostratigraphy - Graphic Correlation • Uses any event that can be tied to the absolute time. • First and last stratigraphic occurrences of taxa (e.g., 1st appearance of P. helvetica in the geologic) • First abundant occurrence of some taxa • Magnetic reversals. • etc.
StrataPlot - Specifications • Standalone Windows application • GUI + Database • Installation: • Application • Data Base • Borland Builder Data Base Engine
StrataPlot - Database • Research localities studied by AMOCO exploration and later donated to EGI by British Petroleum Paleo 24 Oracle StrataPlot DB Paradox
StrataPlot - Public Database • Public Data: • More than 2000 public localities • More than 700 interpreted localities • Six Composite Standards • Time Scale Recalibration • Mesozoic and Cenozoic - Gracianski et al. (1998) • Paleozoic - Gradstein et al. (2004)
