Original Abstract

Using large datasets is becoming more and more common in every discipline. Today's biggest task is to find a tool which would reduce effectively their dimensionality. By the word effectively here it is meant to keep the loss of information within datasets to a minimum, thus maintaining the interpretability of data at a maximum possible level. An example of such a discipline where handling of large datasets is needed on a daily basis is X-ray Computed Tomography (XCT) and Laser-Induced Breakdown Spectroscopy (LIBS). The combination of these two techniques could allow complex analyses of the inner structure of materials. These types of analyses could also help to solve one of the current tasks that archaeologists deal with. This task concerns the study of ancient technology, raw materials and possible origin of the artefacts, such as pottery. Such information are useful to reconstruct ancient manufacturing processes, exchange systems and trade. This method has been tested on samples, which were the result of the extensive investigation carried out between 2015 and 2018 at the UNESCO site Al-Khutm (Bat, Oman). From the archaeological site, about 20 selected samples have been investigated using a multi-analytical approach in order to characterise their microstructure and chemical composition. The results of different techniques, providing a detailed decription of pottery fabrics, have allowed recognising possible local vs non-local raw materials.
