Paleomagnetic dating is based on the fact that
The lacustrine deposits infilling the intramontane Guadix-Baza Basin, in the Betic Range of Southern Spain, have yielded abundant well-preserved lithic artifacts.
In addition, the lake beds contain a wide range of micromammals including .
Dating techniques such as electron spin resonance and thermoluminescence cannot be satisfactorily applied in the strata that contain the archaeological remains because of the absence of the required minerals for such techniques.
Here we report a paleomagnetic age at the localities where artifacts and fossils are found and provide firm age calibration of this important paleoanthropological and mammal site.
Despite the importance of the artifacts and fossil assemblage, estimates of the geological age of the site are still in conflict.Evidence for the oldest hominid settlement in Europe remains highly contentious because of the absence of an accurate chronostratigraphic framework for Lower to Middle Pleistocene sites.Present evidence suggests that the earliest species of during the process, as evidenced by the paleoanthropological sites at Longgupo (China) (1), and Java (2).The two Paleolithic sites studied [BL and Fuente Nueva 3 (FN3)] are located in the northeast of the GB Basin, near the town of Orce (Fig. Both sites are located in the “Silty Calcareous Member” of the Baza Formation (18), which is dominated mainly by limestones, carbonate silts, and dark mudstones.Anadón (19) conclude that this unit was deposited in a lake with an alternation of slightly saline and saline waters.
