Vathi Field Trip 04/09/2016

On Saturday 9th April 2016, the members of the S.E.G. Student Chapter of the Aristotle University of Thessaloniki visited the Cu-Au±U±Mo porphyry system of Vathi, in northern Greece. The Vathi porphyry belongs at the Serbo-Macedonian metallogenic belt, and extends around two hills named Ragian 1 and Ragian 2, in Kilkis province. The main host rock is of trachydacite type which was affected by a hydrothermal alteration attributed to the intrusion of a subvolcanic quartz-monzonite stock. A phreatomagmatic breccia exhibits the highest concetrations of Au, Cu, U and Mo. The ore mineralization occurs as stockworks, sheeted veins as well as pyrite D-veins. The ore mineral parageneses of the porphyry system are mainly chalcopyrite-bornite-molybdenite-magnetite and chalcopyrite-pyrite-magnetite±stibnite which are followed by vein-type pyrite-pyrrhotite-chalcopyrite and sphalerite-galena±arsenopyrite assemblages.

Leader of the field trip was Christos Stergiou, M.Sc. student at the Aristotle University of Thessaloniki, who has just completed his Master Thesis on the Vathi porphyry system which was partly funded by the S.E.G funding programs. This one-day field trip was organized by Janja Michailovich and Eftychia Petika (2015-2016 president and secretary of the chapter respectively) and supervised and co-organized by Vasilios Melfos, Assist. Professor and Academic Advisor of the A.U.Th. S.E.G. Student Chapter.

First Aid training by team “RESCUE GR” 04/16/2016

The “RESCUE GR” is a voluntary rescue and humanitarian organization based in Thessaloniki, N. Greece. Together with the A.U.Th. S.E.G. Student Chapter, we co-organized a free First Aid training for outdoor accidents, for the members of the chapter. The training was conducted on Saturday 16th April 2016 at the National Stadium of Thessaloniki and the participants were trained in providing first aid in cases which may occur in the countryside as wounds, stings from insects and reptiles, stroke, bone fractures etc.

The seminar was successful. The members did practice with each other on how to tie a bandage on various parts of the body. In the end, all the information which the rescue team gave to us remained in our minds.

We would like to thank “RESCUE GR” and the “National Kaftatzoglio Stadium” for the unique experience and knowledge they gave to us!

“Socializing Rocks”


Our forthcoming event will be held during the 13th Student Week of Aristotle University of Thessaloniki and the 1st Thessaloniki Science Festival.

We invite you to explore the magic and wonderful world of geology. Begin your fascinating journey through our interactive exhibition which includes a “geological trip” along the Egnatia Highway in N. Greece, and gaze at the scenery in a different way: the rocks’ way! Watch over the trip of a rock sample from the moment that is picked by a geologist in the field until it becomes part of a scientific paper, and act as a geologist by yourself. A great time is awaiting you to reveal the geological secrets of Galerius palace, the Byzantine churches and the Walls of Thessaloniki. Discover the geological side of our daily life, totally unknown until now!

On behalf of the organizing Committee,
