Stratigraphic Columns Overview
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).
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.
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.
Clicking on the some of the side notes will show pictures pertaining to the note, most especially pictures of unconformities, tracks, and fossils.
