Abstract: This research provides the first evidence of prehistoric quarrying of eclogitic rocks on the Iberian peninsula. Such metamorphosed basic igneous rocks are known to have been used in southern Spain and Portugal during late prehistory as a raw material for the making of polished lithic tools (axes, adzes, chisels, and hammers). These rocks were widely used primarily because of their tolerance to blow and friction due to their mineralogical and textural characteristics. We have identified two quarries within the Sierra de Baza Natural Park (Granada), in the Betic Cordillera of southern Spain: Rambla del Agua and Cerro de San Cristóbal. The bedrock geology of these quarries forms part of the Mulhacen Complex Ophiolite Unit (Nevado‐Filábride Domain), which discontinuously outcrops along a 250‐km belt in southeastern Spain. Petrographic and geochemical analyses were conducted on raw materials from quarries in the Sierra de Baza and compared with archaeological materials from different sites in southern Iberia. These analyses allow us to specify the Nevado‐Filábride‐derived lithic source and define exchange networks. Archaeological sites around the studied quarries chronologically date their use between the early Neolithic and Bronze Age (∼5500–1500 B.C.). [ABSTRACT FROM AUTHOR]

Abstract: The characterization of materials used in the construction of megalithic monuments can be considered a key aspect for a better understanding of the social behavior of past societies. The excavation of four dolmens and one small cist in 2015 at the megalithic necropolis of Panoria (Granada, Spain) offered an excellent opportunity to explore the geological properties and potential source area(s) of the uprights used in their construction. All the stone slabs came from the same raw material: fine‐grained, beige to pink limestones that occasionally show red and black chert nodules, with wavy stratifications and a packstone texture. Comparison with the geological properties of the surrounding outcrops matches a lithostratigraphy known as the Ammonitico Rosso Formation. Thus, it seems safe to say that the quarry area was located next to the necropolis. Explanations other than the traditional practical reasons have been put forward to understand why the stone slabs were quarried from the same mountain in which the tombs were located.
