In June we hosted at the SCEC Anna Tsoupra, our petrography intern for 2024. Anna is in the final year of her Ph.D. at the Dept. of Earth Sciences, Univ. of Evora (Portugal). Her thesis deals with the study and analysis of clayey and tempering raw materials from east Crete and Naxos. Using large-scale geological survey and sampling and a multitude of analytical techniques (optical microscopy, XRD, XRF, SEM-EDS) she investigates the natural properties and the geochemical characteristics of the clays as well as potential inter- and intra-source variation. During the internship Anna used the facilities of the SCEC for the manufacture of thin sections and studied them under the petrographic microscope.
