22/06/2018 – 3rd session of our Informational Talks

Last Friday 22nd of June took place the 3rd session of Informative talks of our Student Chapter. In this occasion, one of our members, PhD student Ariana Carrazana, gave the talk with the title Desde la exploración al cierre de mina: distintas funciones de un geólogo de mineria a cielo abierto” (From exploration to the mine closure: the different functions of an open pit mine geologist), in which she talked about her former work as an exploration geologists in a mining company in Argentina.

The talk covered all the possible jobs a geologist is expected to perform in a mining company, and how they have a major effect in the good development of the mining operations. Her experience was a good example for many students that want to initiate their carriers in mining exploration, and encouraged them to do so. The session ended with some questions and discussions between the audience and the speaker.

We would like to thank Ariana for her instructive talk that allowed us to finish the Informative Talks of this academic year very successfully.


30/05/2018 - 2nd session of the Informational Talks

Last 22nd of March we started organizing a series of talks under the name Xerrades Divulgatives (Informational Talks) in which our student members and collaborators are invited to present a topic related with geology and their studies and experiences. First session was the turn of those students that participated in the field trip to Morocco with the SGA Marrakech Student Chapter. The talk was given by Oriol Vilanova, Berta Sagués, Malena Cazorla, Laura Poll and Joana Lluch, undergraduate Geology students from the University of Barcelona, under the title “Sortida de camp al Marroc” (Field trip to Morocco).
First session

The 2nd session of the Divulgative Talks was last 30th of May. Sebastián Betancur, an undergraduated exchange student from the Universidad Nacional de Colombia, gave the talk “Textures and mineral chemistry of Fe-, Ti-oxide ores in the Santa Marta anorthosite Massif, Colombia”. Sebastián gave a general introduction to the geology of Colombia and centered the talk in the Santa Marta anorthosite Massif, from which he is studying Fe- and Ti-oxides. He shared his experiences in the field during the sampling campaign and his experiences as an exchange student in our university. The audience showed great interest during the talk and found it very profitable. 

Second session


27/03/2018 Antonio Arribas Moreno (1923 - 2018)

The Barcelona Student Chapter announces with great sadness the passing of our Honorific Advisor Antonio Arribas, at age 95, on the 27th of March, 2018.

Antonio Arribas obtained the degree of Natural Science in 1948 and afterwards he graduated in Economic Geology in the Universidad Complutense de Madrid. He was the founder of the Crystallography, Mineralogy and Ore Deposits department of the University of Salamanca in 1965, the first official Ore Deposits department ever settled in the Iberian Peninsula. He was one of the fathers of Ore Deposit research in the Iberian Peninsula and other territories such as the Western Sahara.

We would like to express our condolences to the relatives. 


We would like to celebrate that last 12th of January Lidia Butjosa Molines, one of the first members of our Student Chapter, successfully defended her dissertation and became Dr Lidia Butjosa Molines!

Her 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”, was directed by Dr Joaquín A. Proenza and Dr Antonio García Casco.

Congratulations Lidia!

We wish you a very successful future as a researcher! 

Carl E. Nelson talk and CineForum

Last Friday 16th took place the first Barcelona SGA-SEG Student Chapter CineForum of the year, which was combined with a talk given by the geologist Carl E. Nelson, a consulting economic geologist who largely worked in the Caribbean region with mining and exploration companies and is the president of the consulting firm Recursos del Caribe, S.A. (http://cbmap.net/).

The chosen film for the CineForum session was Gold (2016), which is based on the true story of the 1993 Bre-X mine scandal about a supposed massive gold deposit in Indonesia.

Before the projection of the movie, Carl Nelson gave the talk “Junior Companies: the Risks and Rewards”. He explained the process of starting a mining Junior Company and how it can develop, providing two real examples, one of them being the same on which the movie is based. The talk gave place to some discussion among the assistants and the speaker, and was the perfect introduction for the film.


We are glad to announce that Nils Reinhardt, one of our few foreign members of the Student Chapter, was granted a Master´s degree in Applied Geosciences at the RWTH Aachen University in Germany.


He first came into contact with the Student Chapter while carrying out a year-long Erasmus stay at the faculty of geology of the UB. After moving back to Germany to pursue his Master´s degree studies in Aachen, he then opted to carry out his master thesis project at the UB in collaboration with the RWTH University.

His project “Geochemistry and mineralogy of rare earth elements in bauxite ores of the Llacuna-Medion area, Catalonia, Spain” was supervised by Dr.Joaquín Proenza as well as Dr.Thomas Aiglsperger andDr. Cristina Villanova-de-Benavent, two of the founding members of the Student Chapter. The study focused on the distribution patterns of rare earth elements in Spanish karst bauxite deposits of the Catalan Coastal Range and also represents the first-ever qualitative description of the rare earth mineralogy in these deposits.


Barcelona SGA-SEG Student Chapter’s 6th workshop

The Barcelona SGA-SEG Student Chapter’s 6th workshop took place last 30th of November and 2nd of December, and it counted with the assistance of members from three other international Student Chapters: from Morocco, Freiburg and Greece. The topic of this year’s workshop was PGE / PGM in the oceanic paleolithosphere, an interesting topic due to the fact that platinum group minerals (PGMs) are nowadays listed as critical raw materials based on their economic importance and supply risk. Several experienced specialists on the topic gave talks about the geochemistry of PGE, their mineralogy and petrogenesis, the technics used to analyse them, and insights on PGE experimental mineralogy.

The workshop started the 30th of November with an introductory class to PGE, PGM and PGE deposits, at the Faculty of Earth Sciences of the University of Barcelona. The lesson was divided into a theoretical part, given by PhD student and president of the Barcelona SGA-SEG Student Chapter Júlia Farré de Pablo, and a practical part where Dr Cristina Villanova de Benavent, PhD student Lidia Butjosa and Dr Thomas Aiglsperger showed some hand samples from PGE deposits around the world (e.g. Bushveld Complex, Sudbury, Kambalda, Río Santiago). The lesson was very interactive and was considered very positive by the students.

The conferences were held at the Museu Blau building of the Natural History Museum, in Barcelona, the 2nd of December. Six high-quality talks were given by invited speakers from Granada and Madrid (Spain), Freiburg (Germany), Prague (Czech Republic) and Luleå (Sweden). The talks were followed by scientific discussion generated from the questions made by the audience. We would like to give our most sincere thanks to Dr José María González Jiménez, Professor Fernando Gervilla, Dr Rubén Piña, Dr Malte Junge, Dr Thomas Aiglsperger and Dr Anna Vymazalová for their contribution to our event.

The workshop was completed with a fieldtrip to Bou Azzer (Morocco) in collaboration with the Morocco SGA Student Chapter.
