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. These samples consist of dense mm- to cm-scale layered travertine made up of either micritic or sparry calcite. Individual sample descriptions and locations are found within this table.

Travertine stratigraphy was determined by Ricketts and Karlstrom (2014) mapping, which was based on elevation (e.g. Qtr1 = low elevations = youngest; Qtr3 = high elevations = oldest).
