Activities and Field Trips

The AUTh SEG Student Chapter organized several activities and field trips during the academic year 2017-18, and the participants were involved in various subjects of economic geology. The activities of the student chapter in the academic year 2017-18 are listed in detail below: 1. February 10th and 11th 2018. Field trip to the Pb-Ag-Zn carbonate replacement type deposit in Lavrion (SE Attica, Greece) On Saturday 10th and Sunday 11th February 2017 the AUTh SEG Student Chapter organized a field trip in Lavrion. A group of 9 members of the chapter visited the old mines of the Lavrion ore district. In total 4 undergraduate students and 5 MSc students participated in this field trip together with the Academic Supervisor Associate Professor Vasilios Melfos (Fig. 1). The Lavrion carbonate-hosted Pb-Ag-Zn deposit belongs to the Attic-Cycladic massif and is related with the extensive Western detachment fault system and the Miocene magmatism. The purpose of this field trip was a great opportunity for the students to visit an abandoned underground mine and to be experienced with several ore types in a large area. We saw the characteristics of a porphyry Mo-W type deposit and the alteration zones, a vein type deposit and several carbonate replacement ore bodies. Lavrion is famous for the ancient mining for silver during the Classical period by Athenians and for the large number of rare minerals which have been formed due to the epigenetic oxidation of the mineralization.

2. February 23rd 2018. Masterclass at the Aristotle University of Thessaloniki by Nikos Nestorov, Technical Services Leader of ‘Mavres Petres’ mine, Hellas Gold S.A. On 23rd February 2018 the AUTh SEG SC organized a masterclass with Nikos Nestorov from the Hellas Gold S.A. mining company, as a guest and major lecturer. During a 3-hour interactive class, the lecturer provided several characteristics of the ‘Mavres Petres’ project, including geology, tectonics, stratigraphy, geochemistry, relation of the ore bodies with the host rocks. Then the students had to combine their geological knowledge to gain the points needed to continue to the next level of a real-life exploration project. This helped us to gain experience and confidence to become the leader of the project. It was a competition among us to show who could become the ‘real’ manager of the whole project. This was achieved by only one student in the end. It was one of the most amazing and exciting presentations and all the students enjoyed it.

3. March 3rd 2018. Field Trip to Mavres Petres mine at NE , Greece. On Friday 3rd March 2017 a group of five members of the AUTh SEG Student Chapter (2 MSc students and 3 undegraduate students) visited the exploration program of Hellas Gold S.A. in the Mavres Petres mining area.

Mavres Petres mine is a part of the Stratoni’s underground silver-lead-zinc mine located in the Chalkidiki Peninsula in northern Greece. The deposit is a carbonate replacement deposit hosted in the marble of the Kerdyllia Unit of the massif. The deposit is found along the south dipping Stratoni Fault, a major structural feature and an important mineralizing corridor in NE Chalkidiki. The fault separates the Kerdylia Unit to the north, which hosts the carbonate replacement deposits, from the Vertiskos Unit to the south, which hosts several porphyry gold-copper mineralizations including the Skouries deposit. Mineralization along the Stratoni Fault extends for at least 8 km and include the historically mined Madem Lakkos deposit to the east of Mavres Petres, and Piavitsa, to the west. The students experienced the processes held during the underground exploration by drilling, and the correlation of the raw data coming from the drilling (Fig. 2). They also took part at the geological logging of some drill-cores and had a meaningful conversation with the Technical Services Leader Nikos Nestorov, to get as many information as they could about this exploration project and the various issues a geologist is facing (Fig. 3).

4. August 31st and September 2nd – 3rd 2018. Collaboration with SGA Baltic Student Chapter and Field Trips to Vathi and Rizana deposits (, Greece) and Maronia deposit (Rhodopi, Greece). Between Friday August 31st and Monday September 3rd 2018 the AUTh SEG Student Chapter welcomed to Thessaloniki and offered a guided tour at selected Tertiary ore mineralizations of N. Greece to a number of members of the SGA Baltic Student Chapter. Leaders of the visiting group were Krzysztof Foltyn and Slawomir Mederski the President and the Vice-President of the SGA Baltic Student Chapter respectively. The members of the student chapter were from the AGH University of Science and Technology of Krakow, Poland. During the first ice-breaking day, a presentation meeting was held at the School of Geology, Aristotle University of Thessaloniki. The AUTh SEG student members had the opportunity to be informed on the geology and the various types of ore deposits of Poland focusing at the Kupferschiefer and the Mississippi Valley type deposits. The Polish students brought several representative samples from these deposits and we had the opportunity to discuss the details of the mineralization. In respect, the visiting students were introduced by Associate Professor Dr. Vasilios Melfos to the Oligocene-Miocene ore deposits and mineralization of the Serbo-Macedonian and Rhodope metallogenic provinces in Northern Greece, and by Christos Stergiou (PhD candidate and member of the AUTH SEG student chapter) to the porphyry Cu-Au deposit of Vathi in the Kilkis ore district. During the first field-trip day, on Sunday September 2nd a joint group of students from both chapters visited two representative ore mineralizations of the Kilkis ore district at the Serbo-Macedonian metallogenic province, under the guidance of Eftychia Petika (AUTh SEG SC President) and Christos Stergiou (Geologist MSc-PhD candidate). The group explored the Vathi Cu-Au±U±Mo porphyry system which extends in an area of approximately 3 km2 and is hosted within qtz-monzonite dykes and a trachydacite porphyry. Later on that day the group visited the stibnite mineralization of Rizana. At the Rizana area the ore mineralization is hosted in quartz veins crosscutting Paleozoic gneisses of the Vertiskos Unit and is related to a NW-SE trending shear zone. Vaggelis Skoupras, a MSc student who studies the Rizana

5 mineralization, guided the group around the ore bearing outcrops and the old mining excavations. On Monday September 3rd the group travelled to the eastern part of Northern Greece at the coastal area of Rhodopi county. We visited the Maronia Cu-Mo-Re-Au porphyry mineralization which is related with a porphyry microgranite (Fig. 4). The group explored the sodic-potassic, the propylitic, the sericitic, and the argillic hydrothermal alteration zones of the system. Furthermore, along the Aegean seashore, we looked at the A-, B- and D-type veins of the porphyry system, and collected samples of the quartz- molybdenite vein mineralization. In addition, the group visited the major supra-detachment fault of Marmaritsa which shapes the shoreline at an E-W trending direction.

5. September 27th and 28th 2018. Field trip to epithermal and porphyry mineralizations of the Serbo-Macedonian Massif (FYROM). On Thursday 27th and Friday 28th September 2018 the AUTh SEG Student Chapter organized a field trip in the Former Yugoslavian Republic of (FYROM). In this field trip 2 PhD Students, 8 MSc Students and 1 undergraduate Student participated, guided by the Academic Supervisor Prof. Vasilios Melfos and Prof. Goran Tasev, from the Faculty of Natural and Technical Sciences of the University "Goce Delcev" in Stip. The members of the AUTh SEG Student Chapter visited the Plavica epithermal deposit and the Buchim porphyry type deposit. The high sulfidation epithertmal Au–Ag–Cu deposit in Plavica is situated at the Kratovo–Zletovo volcanic field which includes several Au- Ag-Cu mineralizations. The Plavica deposit is related with a large Neogene volcanic center. At present, Plavica is under exploration by ‘‘Genesis Resources Ltd’’ (Fig. 5). The students visited the lithocaps of the epithermal system and examined the hydrothermal breccias, the vuggy silica and the alunite alterations surrounded by kaolinite alteration. The Buchim porphyry copper mineralization is a world-class deposit situated at the border area between the Serbo-Macedonian massif and the zone and in terms of metallogeny it belongs to the Lece-Buchim-Kilkis-Chalkidiki metallogenic zone. The deposit consists of three types of ore: oxide, secondary sulfide enrichment and primary sulfide ore (mainly chalcopyrite mineralization), and four ore bodies: the Central, Bunardzik, Vrsnik ore bodies related to andesitic porphyry intrusions and the Cukar body, consisting of a supergene copper mineralization. The students visited the Vrsnik open pit mine (Fig.6) which is inactive and collected several samples of the altered andesite with chalcopyrite mineralization. The members of the AUTH SEG Student Chapter visited also the flotation and the leaching installations and were informed about the enrichment of the copper minerals.
