Environmental conditions and geomorphologic changes during the Middle–Upper Paleolithic in the southern Iberian Peninsula
(Elsevier, 2013)
This study utilizes geomorphology, marine sediment data, environmental reconstructions and the Gorham's Cave occupational record during the Middle to Upper Paleolithic transition to illustrate the impacts of climate changes ...

Modelling the mid-late Holocene evolution of the Huelva Estuary and its human colonization, South-Western Spain
(Elsevier, 2018)
The major changes that occurred in the southwestern estuaries of the Spanish Atlantic coast during the last 6500 yr BP were simultaneous to human settlement and therefore the understanding of their coastal evolution will ...

U-series dating of speleothems from the Sierra del Endrinal (Grazalema Mountains, S Spain)
(Elsevier, 2012)
The uranium-series method is applied to date relic flowstone from karstic mountains in the south of Spain. Geomorphological mapping shows three staircased erosion surfaces with a typical karst landform. Exhumed flowstones fill ...

U/Th dating of impure carbonates: 230Th/232Th activity ratios in detrital material
(Springer, 2019)
In environmental age dating the 230Th/232Th activity ratio is widely used as an indicator of detrital contamination. A clear relationship between this activity ratio and the carbonate sample’s age has previously been ...

Evidence of MIS 5 sea-level highstands in Gebel Mousa coast (Strait of Gibraltar, North of Africa)
(Elsevier, 2013)
The Last Interglacial is considered the most suitable episode from which to infer patterns of rapid sea-level change since its climatic conditions were similar to those of the present interglacial. However, specifying the ...

U-series dating applied to speleothems from Los Covachos Cave, South of Spain
(Springer, 2013)
U-Series dating method is applied to speleo thems from Los Covachos Cave in the south of Spain. A combination of solvent extraction method with ion exchange resins is used for uranium and thorium isotopes. Uranium ...
