The Guinardera quarry (Sant Martí de Tous, Barcelona): A new chert exploitation location during historical times

2021-12-28T19:59:03+00:00

In 2014, an anthropic accumulation of chert material was discovered in La Guinardera area, at the southwest of the Sant Martí de Tous town (Barcelona, NE Iberian Peninsula). In 2018 a first archaeological intervention was carried out in two locations: La Guinardera and La Guinardera Nord. After the fieldworks, these two accumulations were interpreted as chert workshops. These workshops are in the St. Genís Formation, included within La Noguera lacustrine system and dated to the Priabonian age (upper Eocene). The St. Martí de Tous area presents shallow lacustrine conditions typical of sabkha environments, in which layers of gypsums and sandy lutites are interspersed with tabular red sandstone levels, yielding different varieties of chert.

The Guinardera chert is characterized by a fairly homogeneous matrix, presenting a fine texture, with a microcrystalline and spherulitic length-slow chalcedony matrix, and a combination of grey colours, in general of dark hues, with an opaque diaphaneity but translucent at the edges.

The archaeological assemblage from La Guinardera Nord site allows us to identify a chert workshop for the production of gunflints. The heterogeneity of the assemblage at La Guinardera site precludes assigning it to any single chrono-cultural period or function.

The technological characterization of La Guinardera Nord site reveals distinctive attributes of a gunflint workshop that can be differentiated from prehistoric workshops. The presence of square and thick preforms, oxide traces on butts and ventral faces, marked bulbs and thick platforms, together with fresh edges on flakes and blades and the near-absence of patinated materials, corroborate it.

The presence of these two deposits within the above-mentioned formation shows us a repeated landscape exploitation pattern for raw material extraction, since references chert use range from the Middle Palaeolithic (e.g., Abric Romaní) to historical times (e.g., La Guinardera Nord).

Knapping before and after polishing: Technological evidence in the Neolithic polished stone tools from Hungary

The authors present the evidence gathered during the interdisciplinary study of several polished stone tools from some Neolithic sites in Hungary. In particular, the cutting-edged tool production (axes, adzes, chisels) involves knapping at several stages of the operational-chain within an artefact’s ‘life cycle’ - from raw material procurement, its manufacture, use, and discard. Some specific fine-grained and non-siliceous raw materials, among which are mainly hornfels, “white stones” and a few greenstones, show evidence of being worked by knapping as shown by the recovery of rough-outs, flaked similarly to biface artefacts, reworked pieces during retooling attempts, and several flakes detached before and after polishing the artefact surfaces. These latter demonstrate that re-sharpening and re-working polished cutting-edged tools was a common practice within the settlements during the whole Neolithic period. These small flakes, that sometimes look like true bladelets, have been often confused with, and published as, chipped stone tools. Therefore, it is important to get a holistic view of the whole stone industry during the study of the lithic assemblages. As in the case for chert and flint in N Europe, which have been intensively exploited for the production of polished axes and adzes, some other lithic raw materials could be easily worked by knapping for the production of polished tools, especially micro-crystalline rocks that have technical response and physical properties very similar to true flint and chert. Moreover, there are indeed implications regarding social organization among Neolithic communities, not only from the point of view of raw material procurement. Notably, the technical capability of producing and maintaining in efficiency the polished stone tools had to be acquired by individuals belonging to each household within the community, since stone axe-adzes were polyfunctional tools for mundane and multiple tasks. Therefore, as an important means for survival, the production of stone tools, both chipped and polished, was a knowledge certainly transmitted from generation to generation, although we still have to understand the modes and social implications of the transfer in details.

Use-wear and residue analysis of knapped stone artefacts from Lepenski Vir and Padina (Serbia)

Following a series of published analyses ranging from architecture to prehistoric diet of the Iron Gates’ inhabitants, our research aims to present new results regarding use-wear analysis of knapped stone artefacts from Lepenski Vir and Padina with a particular focus on the transition from Mesolithic to Neolithic in this region. Use-wear and residue analysis are applied using the low and high-power approach by Optical Light Microscope (OLM) observations combined with FTIR analysis.

Based on the results, some of the main activities that took place in Iron Gates are processing of hide, bone, antler, plants, and soft stone. It is very important to highlight the complexity of various processes, which make this already specific area more peculiar. A variety of both simple, but overall, more complex and composite activities are recorded with the elaborate preparation of the used materials, for example, hide. Particular processes, such as butchering, were noted both inside the houses, and also concentrated in precise, specific areas of the settlements, where only tools involved in the processing of hide and meat were found. The data obtained highlight the activities of these advanced hunter-gatherer-fishermen and first farmers communities. Together with spatial analysis, the dynamics and processes in the Late Mesolithic and Early Neolithic are revealed, but also many questions regarding the specialization of the prehistoric settlements on the Danube are posed.
