	abstract = {<p>Stable carbon and oxygen isotopes in soil carbonates provide an additional technique for investigating Quaternary ecogeomorphic changes in arid and semiarid regions. This study presents d<sup>13</sup>C and d<sup>18</sup>O values in surface and buried soils in a Basin and Range region of southern New Mexico and west Texas. Three landform categories were investigated for their isotopic content: (1) middle piedmont slopes; (2) a lower piedmont slope and adjacent playa depressions; and (3) an intermontane basin floor. Soils of the middle piedmont slopes had greatest d<sup>13</sup>C variability, ranging from -0.6{\textperthousand} in buried soils to -11.1{\textperthousand} (PDB) in surface soils. Soils of the basin floor had greatest variability in d<sup>18</sup>O values, ranging from -0.6 {\textperthousand} to -7.6{\textperthousand} (PDB). Fossil pollen patterns roughly paralled d<sup>13</sup>C shifts, with Cheno-Am pollen exhibiting greatest changes. Both isotope and pollen data across stratigraphic discontinuities suggest that a conversion from C<sub>4</sub> grasses to C<sub>3</sub> desert shrubs accomopanied Holocene erosion. {\textcopyright} 1998 Elsevier Science B.V.</p>
