Stratigraphic Columns Overview

Section Summary
Accessible from the selection map, 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 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 take you to a link of the thickness map with the selected formation’s thickness. .

Rock Type Symbol
Clicking on the rock type symbol will show pictures of the formation with emphasis on 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.

Column Name
Clicking on the column name or some link next to it, will open an album of aerial pictures for the area, or pictures that show areas with large exposures of many fms.

Strat Columns Selection Map

Go to the Strat Columns Selection Map
This map allows you to select strat columns from an interactive map. Simply click on an icon.

Geologic Layer Thickness Map

Go to the Layer Thickness Map
This map allows you to query the database which builds the stratigraphic columns. You can enter your desired geologic formations and have the thicknesses of these layers throughout the state returned on a map.
