Stratigraphic Columns Overview
Section Summary
Accessible from the selection page, the stratigraphic columns section will
eventually be one of the most extensive parts of our database. At some point, this section will contain hundreds
of stratigraphic columns from all over the Colorado Plateau. The columns will follow the standard USGS format for
stratigraphic columns, containing columns for formation and group/member names, age, thickness, and lithology.
Because the internet allows more interaction,
however, every part of the columns will be linked to more data. Below (coming soon) is an example of the interactive
nature of the columns, and a description of what each link does.
Geologic Period Column
Clicking the geologic period in this column will take you to the corresponding paleogeography page for that
period (see paleogeography section).
Formation Column
Clicking on the formation column will take you to pictures of that formation in our
formation image database. The
pictures will be representative of the formation in that particular strat column area. At some point, these
pictures will also have links that will take you to the formations page found in the geologic
formations section of this website, which will in turn have links to cross sections, thickness maps,
pictures, and the users forum where viewers can submit pictures of formations and add their own comments and
insights to them.
Thickness Column
Clicking the given thickness in the thickness column will show pictures that try to show the entire thickness
of the layer in the given area.
Rock Type Symbol
Clicking on the rock type symbol will show pictures which show significant bedding patterns and other up-close
detail information.
Side Notes
Clicking on the some of the side notes will show pictures pertaining to the note, most especially
pictures of unconformities, tracks, and fossils.
