This is a semiarid area that favours high erosion rates. An evolutionary model of the Jubierre hills is presented that shows the environmental cycles represented by aggradational and degradative processes on the slopes that resulted in the present arrangement of talus flatiron rings. In the four studied cases, talus relicts are composed of detritic material from a disappeared caprock pediment. Four slope stages (S4 to S1) that formed under stable climate conditions are identified. Older stages (S4 and S3) are estimated by comparison with other talus flatirons in the region. The S2 stage contains Bronze Age archaeological remains and the radiocarbon age obtained was 1608-1446 years cal BC (2 sigma), while S1 is younger. A palaeoenvironmental interpretation was made for these aggradational stages (S4 to S1). The active erosion of these hills led to a relief inversion, and talus flatirons remain as the only features revealing the presence of the relict hills and past human occupations. info:eu-repo/grantAgreement/ES/MINECO/HAR2014-59042-P info:eu-repo/grantAgreement/ES/MINECO/HAR2015-65620-P info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.8 2022 GEOSCIENCES, MULTIDISCIPLINARY 95 / 202 = 0.47 2022 Q2 T2 WATER RESOURCES 45 / 103 = 0.437 2022 Q2 T2 ENVIRONMENTAL SCIENCES 162 / 275 = 0.589 2022 Q3 T2 0.599 2022 Soil Science 2022 Q2 Earth-Surface Processes 2022 Q2 Geology 2022 Q2 Water Science and Technology 2022 Q2 Pollution 2022 Q2 Environmental Chemistry 2022 Q3 Global and Planetary Change 2022 Q3 5.2 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Sampietro Vattuone, María Marta Picazo Millán, Jesús, V.
