Abstract

This work introduces a comparative collection located in the Prehistory Laboratory at the University of León (Spain) specialised in knappable raw materials, mainly comprising radiolarite and black chert (micro-crypto crystalline quartz), from the western Cantabrian Mountains (north of Iberian Peninsula). A standardised protocol of sample collection and data organisation was developed, which includes the use of several methodologies. First, Geographical Information Systems (GIS) for referencing lithic sources. Second, direct observation of the sample for the macroscopic characterization, both de visu and stereomicroscope. Third, petrographic microscopy for a description of main petrological, and palaeontological features, complemented with the identification of the different minerals that make up the samples by X-ray diffraction (XRD). Forth, X-Ray Fluorescence (XRF), Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) and Thermogravimetry – Differential Scanning Calorimetry (TG-DSC) for geochemical and thermal features of the samples. Finally, the results of these analyses were entered in a database. All this information is contributing towards the creation of a physical reference collection specialised in local Palaeozoic formations (mostly from Devonian to Carboniferous) that outcrop in the western Cantabrian Mountains, a region whose potential resource base was previously not very well known. This collection would allow to compare archaeological lithic remains from different sites inside and outside the Cantabrian Mountains.
LegioLit:西班牙León大学史前史实验室的可拆卸材料石刻
这项工作介绍了位于León(西班牙)大学史前史实验室的比较收集,专门研究可提取的原材料,主要包括放射石和黑燧石(微隐晶体石英),来自坎塔布里安山脉西部(伊比利亚半岛北部)。制定了样本收集和数据组织的标准化协议,其中包括几种方法的使用。首先,地理信息系统(GIS)用于参考岩石资源。其次,直接观察样品进行宏观表征,包括肉眼和体视显微镜。第三,岩石显微学用于描述主要的岩石学和古生物学特征,并辅以x射线衍射(XRD)对组成样品的不同矿物的鉴定。利用x射线荧光(XRF)、电感耦合等离子体发射光谱(ICP-OES)和热重-差示扫描量热法(TG-DSC)分析样品的地球化学和热特征。最后,这些分析的结果被输入数据库。所有这些信息都有助于建立一个专门研究坎塔布连山脉西部露头的当地古生代地层(主要是从泥盆纪到石炭纪)的物理参考资料集,该地区的潜在资源基础以前并不为人所知。这些藏品可以用来比较坎塔布连山脉内外不同地点的考古石器遗迹。
