- Abstract
- Gran Dolina is a cavity that belongs to the second level of the Sierra de Atapuerca multi-level karst system and shows an Early and Middle Pleistocene sedimentary infilling 25 m thick, divided in eleven lithostratigraphic units. High densities of remains have been found in Gran Dolina, including hominid bones, fauna and lithic tools. The use of 3D models in stratigraphy and sedimentology is a new topic that allows new analysis and studies, increasing the knowledge of archaeological sites. In Gran Dolina site, the application of 3D laser scanning and photogrammetry techniques have allowed performing 3D models, including RGB textures. The models were georeferenced to the excavation local coordinate system. From these 3D models, we identified and mapped the continuity and geometry of the sedimentary levels, reconstructing the site's original stratigraphy. The 3D geometry of the levels was used to measure the clasts' textures and the post-depositional dips of the layers. The latter helped us to infer input strikes as well as their variations in each level, and to recognize ancient sedimentary entrances.
