A total of 45 individual travertine samples were collected along a 10 km trace of the Santa Fe fault zone. Travertine samples were collected from low (Qtr1; basin floor), middle (Qtr2), and high (Qtr3; Lucero Uplift) elevations near east- and west-dipping faults and at the main exposures within the Santa Fe fault zone. Of these 45 samples, 25 representative samples were selected for geochronological and geochemical analyses. Travertine layers were micro-drilled to provide enough powder (~150 mg) for carbon, oxygen, and strontium isotope analyses. Here we show the δ13C, δ18O, and 87Sr/86Sr dataset for travertine samples. δ13C and δ18O samples were analyzed at the University of Kansas' KECK-NSF Paleoenvironmental and Environmental Laboratory using a Thermo Scientific Kiel IV Carbonate Device interfaced to the inlet of a ThermoFinnigan MAT 253 dual inlet mass spectrometer. Sr samples were analyzed at the Center for Earth and Environmental Isotope Research at the University of Texas at El Paso using a Nu Plasma multi-collector inductively coupled plasma mass spectrometer after Sr separated and purified using ion chromatography procedures.
