2 ANNUAL REPORT OF THE SEG STUDENT CHAPTER OF BARCELONA APRIL 2017 TO APRIL 2018 The activities organized by the SGA-SEG Barcelona Student Chapter for the last year are detailed below. 1-CONFERENCES 20th of September 2017, Professor Robert F. Martin gave the talk: The clusters of accessory minerals in Grenville marble crystallized from globules of melt 15th of December 2017, Sandra Amores Casals defended her PhD thesis entitled: Evolución metalogenética de complejos carbonatíticos en context hipoabisal y plutónico: Bonga y Monte Verde 12th of January 2018, Lidia Butjosa Molines defended her PhD thesis entitled: The Petrogenesis of the ophiolitic mélange of central Cuba: origin and evolution of oceanic lithosphere from abyssal to subduction and suprasubduction zone settings 16th of January 2018, Carl E. Nelson gave the talk: Junior Companies: the Risks and Rewards 2- FIELD TRIPS: GUADALCANAR (SEVILLA, SPAIN) A field trip to Guadalcanar (Sevilla, Spain) took place from the 16th to the 20th of November 2017 to visit and sample the Guadalcanar mines. These mines were very important in Spain between the XVI and XVII centuries. The main product extracted was silver and old descriptions include Ni-Co arsenides and some analyses performed 1

3 by Abbé Hauy showed platinum content. However, no detailed studies have been performed. The participants of the field trip were Dr Joan Carles Melgarejo, professor of the University of Barcelona and advisor of the SGA-SEG Barcelona Student Chapter; Dr Marc Campeny, curator of the Museum of Geological Sciences of Barcelona, and Joana Lluch, an undergraduate student member of the SEG and our Student Chapter who is developing her Bachelor Thesis on the subject. This field trip had been planned for a year, but the old galleries of the mines are located in private properties and only some months ago we were given the permission to visit them. Further details about the budget of the field trip and the preliminary results obtained will be provided further below. 3-WORKSHOP This year our Student Chapter organized a workshop about PGE/PGM in the oceanic paleolithosphere. The workshop took place last 30 th of November and 2 nd of December of 2017, and it was sponsored by the Society of Geology Applied to Mineral Deposits (SGA) and counted with the collaboration of the Natural History Museum of Barcelona. The event was open to everyone, including both SGA and SEG Student Chapters. For this reason, three members from the SEG Student Chapter of Thessaloniki (Greece) could attend and participate in the workshop. 4-ORGANIZED COURSES: LEAPFROG GEO COURSE For being SEG members, Aranz Geo, which is currently Seequent ( offered us 20 academic licenses of the 3D modelling software Leapfrog Geo ( The software has applications that can be used for several disciplines in geology: ore deposits, hydrogeology, etc. Thanks to this opportunity, the members of our Student Chapter could use the software in their academic projects and research, counting with the technical support and advice from Carlos Alonso and Clare Baxter. However, in order to make the software more accessible to students and to encourage them to use it in their future projects, we decided to organize an introductory course to Leapfrog Geo. The course was given by Clare Baxter from 18th to 20th of December 2017 in the Faculty of Earth Sciences of the University of Barcelona. There were a total of 22 2

4 participants: 3 professors, 4 researchers and 15 students (undergraduated, master students and PhD students). From them, 10 participants were SEG members. The course was centred in two real cases which allowed the students to cover the following topics: - General vision of the software, methodology and implicit modelling. - Import drilling, grade and lithology data. - Create topography, importing GIS data, maps and pictures. - Create a simple geological model from a geological map. - Create and edit geological surfaces from the created model. - Dynamically update the geological model using filters and new data. - Create combined models. - Create a complex models including grades and values interpolation. - Information layout. The expenses derived from the course (flight ticket and accommodation for the trainer) were covered by the Faculty of Earth Sciences (University of Barcelona). The university decided to cover the expenses in exchange for the course to be open to the rest of the Faculty. For this reason, the participants to the course were both members and non-members from our Student Chapter. 5-ATTENDED CONFERENCES Last year, two of our members attended several congresses in order to present the preliminary results from their PhD studies. We encourage our student members to participate both in conferences and congress in order to show the research work they are developing and to start a networking that may be useful in their career and future projects. The attended congresses were: the Goldschmidt 2017 (Paris, France), the 14th Biennial SGA Meeting (Quebec, Canada), and the XXXVI Reunión de la Sociedad Española de Mineralogía (Oviedo, Spain). 6-OTHER ACTIVITIES Regular meetings During the academic course we have been meeting regularly in order to propose activities and discuss and prepare them. The meetings are once per month. 3

5 Cinema Forum We organise sessions called Cinema Forum. These sessions are an opportunity to watch a movie or documentary related with economic geology and ore deposits which can raise later scientific discussion about the topics appearing in the film. Both students and professors are invited to participate in the event. We try to combine these events with a talk related to the topic of the film. Coffee stand At the beginning of the academic year we organised a coffee stand in order to enhance our visibility within the Faculty and to encourage students to join the Student Chapter. Student Chapter T-shirts In order to raise some fund for our activities, we designed some years ago a T-shirt with our logo and the motto all you need is ore. We have been producing them since them and selling them among our members and non-members. Christmas raffle Another initiative that we initiated in order to raise money is the annual Christmas raffle before Christmas holidays. The participants can win a Christmas basket. This year we have been able to sell 300 numbers. 7-USE OF FUNDING FROM THE STEWART R. WALLACE FUND Our Student Chapter received from the Stewart R. Wallace Fund in Last year we decided to use the funding to cover part of the expenses of a field trip to Guadalcanar (Sevilla, Spain), but it was not until the end of last year that it was possible to visit the mines. The aim of this field trip was to perform an accurate sampling of the galleries of the mines in order to study the mineral paragenesis and sequence and the ore deposit model. To develop this research, we counted with the support of our advisors and other specialists like Dr Antonio Arribas. This year we were finally authorised to visit the old mines. The development of this research project is included in the Bachelor Thesis of the student and SGA-SEG Student Chapter s member Joana Lluch. Up to the present moment, the project has developed following the next steps: 4

6 1) Bibliographic research. Compile information about the mines and the ancient exploitations. 2) Field trip to Guadalcanar. As stated before, this field trip took place from 16 th to 20 th of November. The participants travelled from Barcelona to Sevilla by train and then rented a car to travel to Guadalcanar and to the mines. During the field trip two types of mineralization were identified and sampled in different mines and outcrops: mineralization associated to shear zones and late subvertical mineralized veins. a. Shear zones are altering the hosting andesites and black shales producing strong silicification and forming fuchsite. Ores are disseminated and include a fine-grained association with galena, sphalerite, chalcopyrite, pyrrhotite (strongly replaced by pyrite), and possibly arsenides and sulphosalts. b. The late veins mineralizations were the most intensely exploited. The dominant ores discovered until now include a fine-grained association of galena, sphalerite, chalcopyrite, tetrahedrite-tennantite, and possibly fine-grained arsenides. The veins also present calcite gangue. The budget used for the field trip is shown in the table below. Cost Train ticket Barcelona Sevilla 80 x 3 persons = 240 Renting of the car (5 days) 435 Accommodation (4 days) 100 x 3 persons = 300 Meals 150 Conditioning of the mines entrances 100 TOTAL 1225 The received amount from the Stewart R. Wallace Fund was used to cover part of these expenses. 3) 27 thin/polished sections were prepared from the collected samples. The mineralization sequence is being studied using transmitted/reflected optical microscopy and SEM-EDS. EMP analyses will be also performed. The preliminary data suggests that the first type of mineralization may correspond to an orogenic gold deposit associated to regional shear zones. The mineralized veins could have formed by remobilization of the previously formed 5

7 mineralizations and precipitation into fractures. However, further exploration of other targets of the area would be needed to confirm these hypotheses. 4) The preliminary results were presented by the student Joana Lluch in front of a jury in the University of Barcelona, obtaining the maximum qualification. Our aim would be that she could present the final results in a congress once the research is finished and eventually publish them. 8-ACTIVITY PLANNING This year 2018 our Student Chapter participates in a project involving the University of Barcelona and several companies and universities worldwide (universities of Zagreb, Skopje, Agostinho Neto at Luanda, Dakar, NTU at Singapore, Hyberabad in India, the Universidad Tecnológica del Cibao Oriental in Dominican Republic, the Universidad Nacional Autónoma de México, the universities of Recife and São Paulo in Brazil, and the universities of Córdoba, Jujuy and Catamarca in Argentina). The aim of the project is to replicate the teaching mineral collection and material for Mineralogy classes of the University of Barcelona and then donate it to universities from developing countries that are participating in the project. The universities participating are supposed to contribute with samples (when possible) or with the preparation of samples instead. Therefore, the samples constituting the different collections are obtained through donations from universities, but also from museums, mining companies, private mineral collectors, or sampling during field trips. The project will help to build an international network of universities and companies. It will also help to increase the level of training in Mineralogy of Geology students in developing countries, and hence reduce their external reliance, updating the collections in order to meet the knowledge demands of the industry nowadays. Members of our Student Chapter contribute to the project participating in the field trip campaigns to collect samples and classifying the samples once they arrive at university. This supposes and additional practical lesson for students, both in the field identifying the deposits and minerals, and doing classifying work. For some of the field work campaigns, we receive logistical support from the University of Barcelona (car rental for very cheap prices). But we are continuously looking for funding in order to cover some of the expenses. 6

8 Another activity that we are organizing for this year is a two-days field trip to old mines located at Les Bordes de Conflent and at Òs de Civís (~200 km from Barcelona), in the Catalan Pyrenees. This fieldtrip is expected for June, nevertheless the exact date for the excursion depends on the availability of the guiding professors and it will be determined later. The areas that will be visited present several ancient mining galleries that were exploited during medieval times and probably also by the romans. The geology is characterized by several E W thrusts dipping towards N with Silurian black shales as their detachment levels. These thrusts and some intersecting fractures are mineralized. The mineralization consists of siderite associated to pyrite, chalcopyrite, arsenopyrite, copper and tetrahedrite associated to native gold. The deposits have been classified as orogenic gold deposits. This field trip would be limited to 8 people, including the guides. The reason for that is the difficulty to access some of the roads and mines, which compels us to use two 4x4 cars. Our Student Chapter would like to be able to cover the car renting expenses, whereas the rest should be covered by the participants. The expected budget is shown in the following table: Cost 4x4 car renting (2 cars) ~160 x 2 days = 320 Fuel ~100 Accommodation (1 day) ~20 x 8 persons = 160 TOTAL 580 7
