Presentation Transcript

  1. StrataPlot, a Graphic Correlation Tool for Biostratigraphic Analysis Emil Platon Research Assistant Professor Energy & Geoscience Institute at the University of Utah

  2. This talk • Basic introduction to Biostratigraphy • Graphic correlation method • StrataPlot specifications • StrataPlot demonstration

  3. 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

  4. Biostratigraphy - Geologic Time http://www.ucmp.berkeley.edu/help/timeform.html

  5. Biostratigraphy - Fossils • Macrofossils Ammonites (cephalopods) • very good index fossil • Microfossils Foraminifera (single-celled protists) • Planktonic species - good index fossils http://paleodirect.com/ammonites.htm

  6. Biostratigraphy - Biozonation Interval Zone Total Range Zone Partial Range Zone "sp. i I.Z." c "sp. c I.Z." "sp. f T.R.Z." f i b e "sp. h P.R.Z." h "sp. b I.Z." "sp. e I.Z." Time "sp. a I.Z." "sp. g T.R.Z." a "sp. d T.R.Z." d g After M. Caron, 1979

  8. 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.

  9. Graphic Correlation - Composite Standard

  10. Graphic Correlation

  11. StrataPlot - Specifications • Standalone Windows application • GUI + Database • Installation: • Application • Data Base • Borland Builder Data Base Engine

  12. StrataPlot - Database • Research localities studied by AMOCO exploration and later donated to EGI by British Petroleum Paleo 24 Oracle StrataPlot DB Paradox

  13. 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)
