Abstract

The karstic cavity known as Gran Dolina (GD) is one of the archaeological sites of Atapuerca, located on the southwestern slope of the homonymous mountain range (Duero Basin). The sedimentary infilling of this cavity has a minimum thickness of about 25 meters, and can be grouped into two broad facies: Entrance facies and interior facies. The geometry and structure of the cavity is known thanks to surface observations, combined with geophysical studies by ground-penetrating radar and electric tomography that allow the characterization and architecture of the karst in general. Since the mid-1990s, numerous studies have been carried out for establishing a chronological framework of the sedimentary infilling, and in particular of the horizons containing human fossils. Methods used include paleomagnetism, electronic paramagnetic resonance, luminesce, and uranium series, either applied on the sedimentary matrix (Moreno et al., 2015; Pares et al., 2016) or directly on fossil remains (Duval et al., 2018). Existing data, in combination with new results, reflect a unique record of the Pleistocene in the Iberian Peninsula and Europe.
