Definizione di un protocollo analitico per lo studio archeometrico di materiali piro-metallurgici del sito di Auoam (Marocco)

The purely archaeometric de nition of historical and technological background of extraction techniques and pyrometallurgical processing of metals in Morocco of punic-mauritanian requires the creation of an analytical protocol covering every stage of the metallurgical process. These analysis started in 2011 and involved the development of particular procedure, in order to obtain results in broad-spectrum. The present work is related to the identi cation of metallurgical slags trough different analytical techniques that allow to inve- stigate the individual physical-chemical features of the material. The data where obtained by petrographic analysis, thin-layer investigation, scanning electron microscope (SEM) coupled to the energy dispersion system (EDS), X-ray diffraction (XRD), ther- mogravimetric analysis (TGA) and metallographic investigation. The compendium of the analytical results, are the basis for a development of this procedure working with the open-source GIS sof- tware quantumgis (QGIS). Considering the special input data, it was necessary to have additional information related to satellite images, used to de ne different micro-areas of interest.
