Description: Project Area Regions with Different Stratigraphic Relationships. Unit: Integer, relating to the strtigraphic section in each area.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:1 Pecos Valley Aquifer / Dockum Group - Dewey Lake Formation / Rustler Formation / Salado Fm and Castile Fm / Capitan Reef Complex2 Pecos Valley Aquifer / Dewey Lake Formation / Rustler Formation / Salado Fm and Castile Fm3 Pecos Valley Aquifer / Cretaceous Undivided / Dockum Group - Dewey Lake Formation / Rustler Formation / Salado Fm and Castile Fm / Capitan Reef Complex4 Pecos Valley Aquifer / Dewey Lake Formation / Rustler Formation / Salado Fm and Castile Fm 5 Ogallala Aquifer / Dockum Group - Dewey Lake Formation / Rustler Formation / Salado Fm and Castile Fm / Capitan Reef Complex6 Dockum Group - Dewey Lake Formation / Rustler Formation / Salado Fm and Castile Fm/ Capitan Reef Complex7 Cretaceous Undivided / Dockum Group - Dewey Lake Formation / Rustler Formation / Salado Fm and Castile Fm / Capitan Reef ComplexNote that not all formations are present everywhere within a region.This dataset was prepared to meet a specific purpose as described in the following report, which is available on the TWDB website:Meyer, J.E., Wise, M.R., and Kalaswad, S., 2011, Pecos Valley Aquifer, West Texas: Structure and Brackish Groundwater: Texas Water Development Board, report in preparation.The data used to prepare this dataset is also available in the Brackish Resources Aquifer Characterization System (BRACS) MS Access Database, data dictionary, and raw data files (digital geophysical well logs and water well information).
