As of August 2014, KGS cores totalled 3,010 feet.
September 2014 drilling at the Calvert volcanic ash mine, Landon Draw, and
Borchers Badlands has added another 200 feet and counting.

Stable Isotope Chemostratigraphy
•
Fox & Koch (2003) compiled δ13C values from outcrops throughout High Plains
Aquifer with published biostratigraphic or tephrochronologic dates
•
δ13C values shift from dominantly C3 to heat and arid adapted C4 paleofloras
Data from Fox and Koch (2003)
Modified from Koch (1998)

Research Goals
• Coring operations complete
in McPherson and Harvey
Counties.
•Lithologic descriptions and
isotopic analyses on-going in
McPherson and nearly
complete in Harvey Co.
•Optically Stimulated
Luminescence results
suggest depositional age
below loess deposits are
beyond the limit of this dating
technique (~400 ka)
•Tephrochronology?
Sedimentologic and Stable Isotopic Analyses
Quaternary Loess
Neogene (?)
“McPherson
Formation”
Permian Wellington Formation
•
We need dates!
