Last 12th of September 2019, a meeting took place in the Auditorium of the Museum of the La Plata National University, Argentina, convened by Dr. Diego Guido's initiative (SEG Advisor from the Natural Sciences Faculty and the just mentioned Museum). In the meeting, the president of our Student Chapter, Ariana Carrazana, shared our way of working in the generation of content and the activities related to the study of ore deposits. After the presentation of the Student Chapter, a debate between all the assistants in the meeting took place, where they discussed how the participation and the learning in a Student Chapter can involve students since the beginning of their degrees in Geology.

Inside the international cooperation framework in which it is pretended to promote with the institutions that are associated with us, it was presented the actual situation of the Pilot Project of Mineralogy Collection UB, in which more than 30 different universities are already collaborating (by giving support, giving away samples for the completion of the collections, etc.). In this context, the UNLP Student Chapter gave away enargite samples so that they could be added to the collection.


We feel grateful with the exchanges it has been generated with the Geology students from the La Plata University, with whom we were able to share methodologies, tips, ideas and schemes of how to use different tools to reach a self-learning about geology and ore deposits, which are complementary and extracurricular to the academic formation in the University. These ideas permit us to work in research projects and prepare us to face management and teamwork facts, which are essential nowadays.

We want to thank all the UNLP SEG Student Chapter, the founders of the Student Chapter (since 1998), all the ex-presidents and the teachers from subjects related to the study of ore mineral deposits that did not doubt to assist to this session and to share their experiences.

We wish to continue sharing a lot of new coming projects together.


Last week of August of 2019 took place the 2019 SGA Biennial Meeting in Glasgow, Scotland (from 27.08 - 30.08). Three of our student members assisted to the meeting in order to present their research and the activities we performed in the Barcelona SGA-SEG Student Chapter: Júlia Farré de Pablo and Núria Pujol Solà, both former presidents of the Student Chapter, and Malena Cazorla Martínez, current vice-president.

Núria Pujol Solà presented a poster with the title “Olivine orthopyroxenite-hosted chromitite veins in the ophiolitic mantle, Havana-Matanzas, Cuba, in which she explained the new interpretations regarding the unusual formation of chromitite veins within orthopyroxenite instead of hosted within dunite.

Júlia Farré de Pablo presented a poster of the research she is performing in the framework of her PhD study about the origin and formation of ophiolitic chromitites of Dominican Republic. She also presented the activities performed by our Student Chapter in the last two years in the SGA-General Assembly that took place during the meeting.

Malena Cazorla Martínez did an oral presentation in which she exposed her Bachelor Thesis. Malena’s Bachelor Thesis focused chiefly on the study of the petrology and geochemistry of the Animas-Chocaya-Siete Suyos deposit, Bolivia, which is extremely enriched in indium. She explained that the main reason why the deposit is extremely enriched in indium is because of the high values of indium found in sphalerite, up to 9.5 wt. %.

From June 25th to June 28th , some members of our Student Chapter attended the Spanish Mineralogical Society Meeting (XXXVIII Reunión Científica de la Sociedad Española de Mineralogía) that took place in Ronda, Málaga.

Dr. Thomas Aiglsperger, one of the founders and a regular member of our Student Chapter and nowadays associate Senior Lecturer in the University of Luleå (Sweden) was invited for the seminar with the talk: “Conventional and unconventional deposits of platinum group elements”.

Ph.D. students, and members of the Student Chapter, Núria Pujol Solà and Júlia Farré de Pablo gave 15 min talks related to exotic minerals in ophiolitic chromitites in the ore deposits session.

Our advisor, Joaquín A. Proenza, also gave a 15 min talk about massive sulfide deposits hosted in ultramafic rocks from Cuba. 

During the last day there was a field trip to the Ronda peridotitic massif, observing the different facies of ultramafic rocks and the associated chromitite mineralization. The field trip was led by Dr. Karoly Hidas from the Instituto Andaluz de Ciencias de la Tierra (IACT, Granada).


Last 24th of May, Malena Cazorla was invited to our 8th Informative Talk. Malena Cazorla is a 4th Undergraduate student that participated in the V Jornades sobre el Bosc de Poblet i les Muntanyes de Prades, on November 2018. In this meeting, several people were invited to talk about the Prades Mountains and the Poblet Forest, in order to improve the knowledge related with these areas in terms of history, biodiversity and geology. In the meeting, Malena Cazorla gave two talks entitled "Sal de llop de les serralades costaneres catalanes" (“Sal de llop” at the Catalan Coastal Ranges) and "Minerals industrials del bosc de Poblet" (Industrial minerals from the Poblet Forest). 


For the Informative Talk, Malena exposed the contents of these two talks she gave. Therefore, the main topic was the small-scale mining performed at the Prades Mountains and the Poblet Forest in the last centuries. She focused on the mining of sal de llop (a variety of calcite) and the industrial minerals from the Silurian slates. This type of small-scale mining was very common during the late periods of the Middle Age and the early modern period, as the sal de llop was needed for the production of glass (mixed with an alkali and silica), whereas the industrial minerals, like halotrichite and copiapite, were used as mordant. 


The talk was not only focused on what she exposed at the meeting in Poblet. She also encouraged our student members to participate in these type of meetings. She concluded that this experience gave her the opportunity to learn new things about mining and to get to know some researchers related with the topic and the area (the Prades Mountains and Poblet Forest), and also gave her the opportunity to improve her presenting skills and to gain experience when it comes to exposing. 

Again, we want to thank Malena for giving this talk and for encouraging our students to participate in extracurricular events.

On Friday, April 26, our SEG member, Jingyao Xu, defended her doctoral thesis, directed by Dr. Joan Carles Melgarejo Draper.

She studied the Optimization of the use of diamond indicator minerals in diamond exploration in kimberlites.

We congratulate Jingyao and wish her many successes in this new stage.


Last 13th of March we had the enormous pleasure to have Dan Wood with us, giving a talk about the Discovery of the Kencana Au-Ag ore deposit in Indonesia.

Dan Wood was the SEG Distinguished Speaker during 2018. He is an exploration geologist (nowadays retired) who was associated with a great number of significant ore deposits discoveries. Together with the Company's exploration team of the Newcrest, from which he was the Executive General Manager Exploration, they were judged by the Metals Economics Group of Canada to have been the world's most successful gold explorer, during a long period of time.

The main topic of the talk was the Kencana Au-Ag ore deposit, in Indonesia. This deposit, together with other associated to the main one (Gosowong and Toguraci), is a good example of high grade, low-sulphidation epithermal Au-Ag mineralization. He explained his experience through the discovery, exposing all the analyses obtained with the exploration of each of the deposits. An important fact is that the Kencana deposit is about three times the size of both Gosowong and Toguraci deposits. Dan remarked the important role that perseverance during the exploration process, good field work and even serendipity played in the discovery of this deposits.

We want to thank Dan Wood for such an interesting talk and for giving us the pleasure to hear his experience.


14/02/2019 and 28/02/2019 – METEORITES SHORT COURSE

Last 14th and 28th of February took place the Meteorites Short Course organized by the Barcelona SGA-SEG Student Chapter and given by Dr. Jordi Llorca and David Allepuz at the Faculty of Earth Sciences of the University of Barcelona.

First of all, we want to thank all participants: it was a great experience for us to organize this course and we received very positive comments from all the assistants.

The course was divided in two days. The first day consisted in a theoretical session in which David Allepuz and Dr. Jordi Lorca introduced different terms related to the classification of meteorites and its characterization. They also detailed the procedure they follow in order to sample meteorites and explained their own experiences during the field trips around the world, as well as the excitement they still feel nowadays when they find a meteorite. A place where they usually find meteorites is the Atacama Desert, Chile. The way they did the conference was easy to follow, especially for those who didn’t have any knowledge about the topic.

The second day of the course was for the practical session. In this occasion, we had the chance to take a look at a great number of thin sections, corresponding to different typologies, with optical microscopy. This way it was possible to apply the terms we learned during the theoretical session for the description of the samples. The thin sections were part of the collection available at the Faculty of Earth Science of the University of Barcelona.


The course participants exposed their opinions and said they found the course very interesting. However, they lament the lack of time provided to study the samples considering the amount of samples available.

To conclude, we want to thank David Allepuz and Dr. Jordi Lorca for the interest and dedication they put to organize this short course.

Last 7th of January, Carlos Alonso was invited to our 6th Informative Talk. Carlos Alonso is a senior geologist in exploration and mining, gave us the talk: La Experiencia de un Geólogo Modelador: Optimización de la información geológica mediante el uso de tecnologías avanzadas. The talk was divided in two parts. He first explained how he decided to study Geology and talked about his academic trajectory. He did his Geology Bachelor at the Universidad Complutense de Madrid and decided to direct his career towards mining. During his career, he got the opportunity to start learning softwares to perform 3D geological modeling and decided to specialize on that to apply it within the mining sector. Nowadays he works as Business Development Manager for Seequent, the company which provides the software Leapfrog (www.leapfrog3d.com/), in London (UK).

The second part of the talk was focused on the 3D modeling itself: the different tools it provides and how it can be used to improve and optimize the geological study of an area. He also provided several examples, mainly from South America where he worked for several years, showing its different applications within geology: from 3D mapping of geochemical anomalies within a mine pit, to locating the subduction zones in the Andes Mountains using the information from seismic lines.

He concluded the talk making us aware that all geological data we might have can be modeled as soon as it can be codified and organized in a database. Moreover, any information contained within a database is better understood and can be better interpreted when we are able to easily visualize it, for instance using 3D modeling. Nowadays there are several softwares, like Leapfrog, that make 3D modeling much easier and friendly for all users and it is important for geologists to familiarize with them.


The next 14th and 28th of february is going to take place a short course about Meteorites. The short course consists of two parts:

  • 14th of februrary, 18h - 20h: A theoretical part (introduction to meteorites and sampling techniques)
  • 28th of february, 18h-20h: A practical part (samples under a microscope). 

The course will be imparted by David Allepuz and Dr. Jordi Lorca, owners of the website http://meteorits.cat/For further information, you can send us a message to our e-mail: Esta dirección de correo electrónico está siendo protegida contra los robots de spam.

28/11/2018 – 5 th Informative Talk with Àlex Sendrós

Last 28th of November took place the 5 th session of Informative Talks organized by the Barcelona SGA-SEG Student Chapter. In this occasion, Àlex Sendrós presented the talk “Mineria de la potassa a Catalunya: El paper del geòleg en l’obtenció d’una relació sostenible amb l’ambient” (“Potash mining in Catalonia: The role of the geologist to obtain a sustainable relation with the environment”).

Àlex Sendrós works as an associate professor at the Faculty of Earth Science of the University of Barcelona and also in the Environment Department in the mining company Iberpotash-ICL Group in Súria and Sallent, in Catalonia (http://www.icliberia.com/?lang=en), since 2015.

Àlex talked about his personal experience as a Geology student and how he started working for Iberpotash-ICL Group. He talked about his work in the mine and the different protocols they developed in order to avoid contamination from the mining wastes. His talk was very clear and informative. At the end of the talk the audience asked several questions both related with the mining activities and his job as a geologist in the company, and with the experiences and decisions he made as a student. Àlex ended the session encouraging undergraduate students to travel and learn from different geological and social realities.

We would like to thank Àlex for participating in our Informative Talks sessions.


22/11/2018 – Visit to the Martorell Museum (Natural History Museum of Barcelona) for our 4th Informative Talk

Last 22 nd of November, we visited the Martorell Museum, which is part of the Natural History Museum of Barcelona. We were received by Yousra Haddad Belfkih, member of our Student Chapter, together with Yael Díaz, Marc Campeny and Vicent Vicedo, who are responsible for the petrological, mineralogical and paleontological collections. Yousra is doing an internship at the Museum documenting the petrological collection. To start the visit, they told us that the Museum was built thanks to the legacy that Francesc Martorell i Peña (1822-1878) left to the city of Barcelona in 1878. The Museum has been exclusively dedicated to geological collections since 1924. Then we were able to visit all the facilities. First, Vicent talked about the amount, storage and selection of the paleontological pieces. With Marc, we learnt about the preservation of geological samples and some important safety aspects during the conservation process. Finally, Yael showed us the library, which is specialized in the scientific disciplines of the Museum, the petrography laboratory, and how the team works with historical databases in order to adapt them to new technologies: http://www.bioexplora.cat/ncd/. We also did a small practice cataloging rocks and minerals under the guidance of David Fernández.

We would like to thank the entire team of the Museum for such a warm welcome and for their great predisposition to show us the daily work in the field of conservation and divulgation of geological heritage.
