02/12/2016 -03/12/2016 BARCELONA STUDENT CHAPTER’S WORKSHOP: SKARN DEPOSITS

Due to the high rate of participation in the previous activities organized by the Barcelona Student Chapter, we were more than devoted to the organization of our 5th workshop dedicated to skarn deposits, which was held on the 2nd and 3rd of December at the Faculty of Geology of the University of Barcelona. It counted with the total participation of 29 assistants, some of them even coming from the University of Oviedo, Asturias. The aim of this workshop was to provide an approach of these types of deposits regarding: their structure and genesis, their geochemistry, petrology, mineralogy and a review on the diverse techniques used in their exploration to undergraduate, master and PhD students, as well as for other professionals interested in these typology of deposit.

Morning of day 2nd December consisted of a cycle of conferences in which the followings were imparted: Albert Soler Gil (University of Barcelona) opened the session with an introductory lecture entitled Skarn-type deposits: genetic models in the Iberian Hercynian in which members were enlighted with the different complex processes responsible for the formation of these deposits, their structure, petrochemistry and classification. Proceeding into detail, Abigail Jiménez Franco (PhD student from the Polytechnical University of Catalonia- EPSEM) explained a particular example of skarn deposit with her lecture entitled The Velardeña (Zn-Pb-Cu) Skarn: new data on the mineralogy, fluid inclusions and isotopic geochemistry. Finally, Lluís Boixet Martí (Country Manager; Minería de Corcoesto S.L – Edgewater Exploration Ltd) treated the assistants to a memorable lecture entitled Prospection of auriferous deposits in the Iberian Peninsula. An example: the Carlés Skarn, Asturias in which members were provided not only with academic information but also with a business-exploration point of view.

In the same afternoon, assistants were invited to a 3-hour practical session imparted by Albert Soler that included hand-sample observation of numerous skarn samples and the visualization of the ores of these ones under reflected light microscope . During this session, assistants recognized various mineralogical assemblages of different types of skarns and familiarized with those samples belonging to the deposits visited on the fieldtrip.

The Barcelona Student Chapters one-day fieldtrip, leaded by Albert Soler, took place on the 3rd of December. It consisted on the observation and study of a few distal and proximal skarns located in the Axial Pyrenees, closely related to the magmatic intrusions of the late Hercynian orogeny, which included: an idiocrase skarn, a hedenbergite skarn, a pyrrhotite skarn and an arsenopyrite skarnoid (Fig.6). Assistants were deeply involved and had great pleasure in listening to all explanations regarding the processes associated to the genesis of each of these deposits and had the opportunity to acquire exceptional hand samples.

 

We gratefully acknowledge all lecturers: Albert Soler Gil, Abigail Jiménez Franco and Lluís Boixet Martí for their overwhelming speeches. In addition we express our most true gratitude to the SGA for the economic support offered, which allowed us to develop and carry out successfully all our activities as well as to the Faculty of Geology for their logistic and equipment provided.

Coffee stand 21st September

 
 
On day 21st of September a coffee stand was organized by the SGA-SEG members in order to welcome the new academic year. The planned activities encompassed the whole morning and afternoon and included diverse talks. The first three presentations corresponded to the final degree project of three graduated members from 2016: 
Mineralogía y Geoquímica del Yacimiento de bauxitas Las Mercedes y otros depósitos de la Sierra de Bahoruco, República Dominicana, by Daniel García, Multidisciplinary mineralogical characterization of PGM from the Loma Caribe peridotite, (Dominican Republic), by Sandra Baurier and Geochemical characterization of Late Neogene tephra layers in the Minas de Hellín and Cenajo Basins (SE Spain), by Anna Mireia Rabaza.
 
 
In addition, few members who attended the collaborative expedition with the Siberian Student Chapter this previous summer 2016 reported their experience in a casual and relaxed way before continuing with the welcoming celebration of the new academic year. 

SGA SIBERIAN FIELD TRIP

During the first weeks of last August 2016 and after intense planning, the Siberian Student Chapter and the Barcelona Student Chapter put a beginning to their collaborative expedition fieldtrip. This consisted on the first collaboration with any other Student Chapters from part of the Barcelona Student Chapter and it could not have gone any better, consisting on a thoroughly planned and amazing week-long fieldtrip throughout Southeastern Siberia composed by seven members of each Chapter. 
 
 
During the first days the students had the opportunity to visit some important ore deposits of Siberia: the Kamenushikoe Cu deposit and the Salairskoe Pb-Zn deposit, located 300km from Novosibirsk in the Salair Ridge (Kemerovo Region), and Sinyuhinskoe Au deposit, located in northeastern Altai. The two types of ore commonly found at Salairskoe Pb-Zn ore field were characterized by massive carbonate-quartz-barite ore and disseminated barite-polymetallic ore whereas in Kamenushikoe Cu deposit ore minerals were represented mainly by pyrite and chalcopyrite. In addition, students had the chance to collect amazing hand samples of azurite, malachite and chrysocolla between others. On the other hand, at Sinyuhinskoe Au deposit, members were provided insights on the skarns of different compositions developed in tuffs and carbonate rocks in the contact zone with the Sinyukha massif, mainly on the wollastonite, garnet-wollastonite and pyroxene-wollastonite skarns associated with sulfide minerals. 
 
 
When interning into the Altai Mountains, the Siberian Student Chapter excellently guided the Barcelona members to both geological and cultural places of interest such as a) the largest natural history museum in Siberia; the “Paleopark”, b) the Cambrian – Ordovician Gornoaltaisk formation “Dragon’s teeth”, c) middle Devonian volcanites related to the continental margin in western Altai-Sayan foldbelt activity, d) a bewildering catastrophic glacial megaflood deposit called Inskoy “stone garden”, e) the beautiful confluence of Chuya and Katun’ rivers and its complex terraces, f)  fossil-bearing Silurian limestones belonging to the Gromatukhinskaya series, g) petroglyphs of Turkic peoples (9000-6000 B.C), h) the Kol’ka Snegiryov Monument and j) the well-known Shirlak waterfall and the alluring blue lake near Aktash Village. 
Above all, we want to thank the SGA Siberian Student Chapter for their dedication, their guidance and for having provided and shared such joyful and memorable moments with us and to the SGA itself for having supported this collaborative expedition from the beginning.
