Project Area Regions with Different Stratigraphic Relationships. <\/SPAN><\/P>

Unit: Integer, relating to the strtigraphic section in each area.<\/SPAN><\/P>

This dataset was created for the purpose of defining different regions within the project area that had significantly different stratigraphic relationships between the formations/aquifers. Each region is identified with an integer value ranging from 1-7. The following integers relate the stratigraphy from top to bottom:<\/SPAN><\/P>

1 Pecos Valley Aquifer / Dockum Group - Dewey Lake Formation / Rustler Formation / Salado Fm and Castile Fm / Capitan Reef Complex<\/SPAN><\/P>

2 Pecos Valley Aquifer / Dewey Lake Formation / Rustler Formation / Salado Fm and Castile Fm<\/SPAN><\/P>

3 Pecos Valley Aquifer / Cretaceous Undivided / Dockum Group - Dewey Lake Formation / Rustler Formation / Salado Fm and Castile Fm / Capitan Reef Complex<\/SPAN><\/P>

4 Pecos Valley Aquifer / Dewey Lake Formation / Rustler Formation / Salado Fm and Castile Fm <\/SPAN><\/P>

5 Ogallala Aquifer / Dockum Group - Dewey Lake Formation / Rustler Formation / Salado Fm and Castile Fm / Capitan Reef Complex<\/SPAN><\/P>

6 Dockum Group - Dewey Lake Formation / Rustler Formation / Salado Fm and Castile Fm/ Capitan Reef Complex<\/SPAN><\/P>

7 Cretaceous Undivided / Dockum Group - Dewey Lake Formation / Rustler Formation / Salado Fm and Castile Fm / Capitan Reef Complex<\/SPAN><\/P>

Note that not all formations are present everywhere within a region.<\/SPAN><\/P>

This dataset was prepared to meet a specific purpose as described in the following report, which is available on the TWDB website:<\/SPAN><\/P>
