At Rio Mesa, Utah (USA), we investigated the fidelity of rind records in a river terrace setting by determining the seasonal timing of rind formation and testing for inter-record replication. We infer soil carbonate formed in the spring season, contrasting with our prior inference of summer formation at Teasdale, Utah, \u2248200 km distant. This apparent discrepancy occurs because of differences in the timing of the largest annual infiltration (spring vs. summer). At Rio Mesa, modern soil data show that soil carbonate \u03b413C would have high values (\u22122 to 2\u2030 VPDB) regardless of seasonal activity of C3 versus C4 plants because respiration rate is a strong control. We accordingly suggest reassessment of published records interpreting soil carbonate \u03b413C only via C3 versus C4 plant abundance. Three rind \u03b413C and \u03b418O records generally replicated. Intriguingly, rind \u03b413C may inversely correlate with summer insolation, evidence for global-scale influence on soils. Rind \u03b418O is not as clearly correlated with published western USA paleoclimate records, potentially due to regional differences in climate and because rinds record soil-specific processes. Our results support the fidelity of the soil carbonate rind paleoarchive and suggest that because rind formation seasonality is intimately tied to infiltration seasonality, spatial transects of rind records might be used to delineate boundaries between areas dominated by spring and summer infiltration, permitting reconstruction of the geographic extent of large-scale hydrologic phenomena such as the North American Monsoon.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P13EMTYG", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.68278be2d4be02693eeab8a8.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_68278be2d4be02693eeab8a8", "keyword": ["Colorado Plateau", "Dolores River", "Entrada Sandstone", "Moab, Utah", "Rio Mesa, Utah", "USGS:68278be2d4be02693eeab8a8", "age estimation methods", "farming", "geochronology", "luminescence dating", "optically-stimulated luminescence", "radiation dosimetry"], "modified": "2026-04-30T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-109.1812, 37.7969, -109.1811, 37.7970", "theme": ["geospatial"], "title": "Luminescence data for: Springtime Formation of Laminated Soil Carbonate Rinds and Changes in Fluvial Terrace Soils on Orbital Timescales at Rio Mesa, Utah, USA"}
