Summary of annual activities 1. Regular meetings (From October 2013 to September 2014) We made two meetings per month (some more when it was necessary) to organize the activities of this period. During these regular meetings we assigned to every member of our Student Chapter specific tasks to reach. We organized two very successful short-courses and two conferences with professionals of different private companies who are working in diverse topics related to economic geology (see point 3). Also, we are organizing short-courses programmed for the next period (see point 6). 2. Field trip to Santa Cruz and Chubut provinces, Argentina. Between November 29th and December 8th, 2013, the members of the SEG Student Chapter UNS and Dr. Paul Lhotka organized an eight-day field trip to Chubut and Santa Cruz Provinces that was part of the course Geology and Applied Exploration of the Silver Deposits of the Patagonia Argentina. The course and field trip had the support of the Society of Economic Geologists (Round I 2013 Stewart R Wallace Funding application), COEUR Mining Inc, Mirasol Resources and the Geology Department of Universidad Nacional del Sur (UNS). A group of 10 members of our Student Chapter participated in this field trip guided by Dr. Paul Lhotka (geologist from the mining industry) and the guest professor was Dr Fernando Tornos (Universidad Internacional de Andalucía, España). Two drivers of the Geology Department (UNS) vehicle also traveled with us. During the trip we visited two silver projects. The first one was the Virginia project (-47.478836; -69.955436) located in the center-north of Santa Cruz province in the Deseado Massif. The silver mineralization at Virginia is hosted by quartz epithermal veins with hematite.

3. Organized conferences and short courses On November 8 th, 2013, we invited the professor Dr. Carlos Zavala, to give a conference titled: Hyperpycnal systems: under the sea rivers. Origin, characteristics and distribution of deposits related to hyperpycnal flows. This conference took place in the Auditorium of the Geology Department of our University. The lecture was really interesting and more than 40 undergraduate, PhD students and Professors of our University assisted. Fig. 5.

Down- Left to Right: Carolina Meschini, Ainara Irastorsa and candela Corredera. Right Photo: Candela Corredera, giving a gift to Carlos Zavala in the name of all the members of our Student Chapter. Dr. Fernando Tornos from the Instituto Geológico Minero de España, Spain, was invited by our Student Chapter together with the academic authorities of our University. He gave a course on Geochemistry of hydrothermal processes. This course took place in the Geology Department of our university from 25 th to 28 th, November, 2013. The aim of the course was to understand and quantify the geochemistry of hydrothermal processes, and especially the low temperature hydrothermal processes (<300 C). The course included an update of knowledge on the origin, transport and precipitation of silicates, oxides and sulfides from hydrothermal fluids. One of the objectives of this course was to emphasize the relationship

between purely descriptive geology and the understanding of genetic processes, and extrapolate these processes from small-scale observation to a regional scale. The course included a significant practical component, using calculation programs. About 30 geologists participated, including people from other countries, students, professors of the Universidad Nacional del Sur and others universities of our country. Fig. 6.

Dr. Paul Lothka was invited by the SEG Student Chapter to give a conference in our University. The name of his very interesting talk was Three New Discoveries on Silver Reservoir in Patagonia: 2002-2012: Navidad- Joaquin - Virginia and was held in the Auditorium of the Geology Department from our University the 28 th November of 2013. The talk was just before the field trip organized by the SEG Student Chapter to these projects. We would like to thank very much the help and predisposition of Paul, who made possible to carry out this unforgettable trip. Fig. 10.

We invited Professor Dr. Osvaldo Rabbia, from Universidad de Concepción, Chile, to give a short-course on Formation of Andean Cu (Mo- Au) Porphyries. This short-course took place in our university, from the 25 th to the 28 th of March 2014. Almost 20 people, mostly PhD students from our University and mining professionals working in companies operating in Argentina assisted to this course. Fig. 13. The students during the classes.

In September 2014, we finished the emissions of our radio program in the radio of our university (AM 1240, Bahía Blanca). The name of the program was Rockeando la Tarde ( Rocking the afternoon ). The radio program was about geology in general with emphasis on issues related to mineral deposits. It included interviews with different geologists, both from the academia and the industry. We also had a geotourism section, which explains the geological history of geological sites and localities of Argentina. In the last part of the

program we talk about the latest news from the geological world (mining industry, hydrocarbon exploration and academic research). Fig. 16. The last program of Rockeando la Tarde.

4. Fund-raising programs Our Student Chapter was benefited with the 2013 Round I Chapter Stewart R. Wallace Student Chapter Funding during this period. With these funds together with economic support from the Universidad Nacional del Sur we organized the field-course named "Geology and Applied Exploration of Silver Deposits in Patagonia, Argentina" described in point 2. Additionally, we received funds from Coeur South America (USD 1,000) as a contribution to this field tripcourse described. This economic support helped us to offset part of the expenses (printing field guides, food, hotel, gasoline). A member of our Student Chapter, Candela Corredera received economic support to the SEG 2014 Conference. (September 27-30, 2014) that was held in Keystone, Colorado, USA, where she present a poster about "Discovery, Exploration and Paragenesis of the Virginia Silver Veins, Deseado Massif, Patagonia Argentina", which was held in conjunction with de Azevedo Natalia and Luna Geraldine. The field trip, as well as thin and polished sections were made with funds provided by Mirasol Resouces LTD. The poster for the conference was conducted with funding from the Department of Geology of our University. The authors thank all the support to realize this project.

Wallace Student Chapter Funding. With the help of this grant, we are planning to conduct a course and field trip to the Copahue geothermal field, Neuquén Argentina, in February 2015. In geothermal environments, primary minerals usually tend to alter to secondary (hydrothermal alteration) minerals that are either stable or at least metastable in these environments. The formation of these hydrothermal alteration minerals is usually dependent on the temperature, permeability, pressure, fluid composition, initial composition of the rock and the duration of the hydrothermal activity. These factors are largely independent, but the effects of one or more of the

factors can exert a dominant influence in the location and extent of hydrothermal alteration. The topics that are going to be addressed during the theoretical classes of the course are: Alternative and Renewable Energy: Energy Market. Types of energy. Environmental aspects. Economics. Rational use of energy. Geothermal Energy. Fundamentals. Exploration and development of geothermal resources. Geothermal Energy in Argentina and the Neuquén Province. Copahue Geothermal Field. During the field trip we plan to undertake a review of the geological, volcanological and structural aspects of the Copahue Geothermal Field, hydrothermal areas, thermal manifestations and alterations. Exploitation of the geothermal power generation and direct uses. We will observe in this field trip an active hydrothermal system. 6. Future plans We are organizing 6 (six) conferences and 2 (two) short-courses (one of them, with a field trip) for the next period (October 2014- September 2015). The first conference will be held by the postgrade student Verónica Bouhier (CONICET-Centro Patagónico de Estudios Metalogenéticos). She is doing her PhD thesis in the Navidad Project, a polymetalic (Ag, Pb, Cu and Zn) worldclass deposit located in Chubut Argentina. The title of the conference will be: Analysis of Alteration and Mineralization in Galena Hill, Navidad District, Chubut Argentina. This conference will be held on 20th October 2014.

She investigates the Cu-(Au) porphyries recently discovered in the High Cordillera of San Juan Province, Argentina. Her PhD thesis included the metallogenic study of the Cu-(Mo-Au) porphyry Altar and the Miocene igneous rocks of the region. She is going to offer a talk about Cathodoluminescence and trace elements in quartz from porphyry-type and associated epithermal ore deposits The fifth conference will be in charge of the PhD student Ana Laura Rainoldi, she is investigating sedimentary copper deposits associated with the migration of hydrocarbons in Neuquén Basin, Argentina. The title of the conference will be: Alteration of Red Sandstone, Huincul Formation (Neuquén Group). Evidence

of Hydrocarbons Migration in Dorso de Los Chihuidos Region. This conference will be held on July 2015. The sixth conference will be held in August 2015 in charge of Violeta Gonzalez. She is doing her PhD thesis in Mo-Cu porphyry deposits in the Patagonia Argentina. She will give a conference titled Geology, Geochemistry, Geochronology and Genesis of the Prospect El Porvenir-El Refugio, Chubut, Argentina. Tectonic and Metallogenic Implications. The first short course and field trip is about the Copahue Geothermal field, in Neuquén Argentina described in point 5. The second short-course is titled "Epithermal deposits: characteristics, survey and research" by Dr. Diego Guido and Dr. Sebastian Jovic from Universidad Nacional de La Plata. It will be held in March 2015. This course will include an introduction to the knowledge of epithermal deposits, their examples, the most important characteristics, classification and distribution, environment and metallogenesis. The second part of the course will gives an introduction to the methodology of exploration, research and recognition of the main features from the mesoscopic to the microscopic level. The course will include theoretical classes and practical observation with hand samples and thin sections. The theoretical and practical classes will be supported with artwork guide (powerpoint), photo (slides, powerpoint) and samples of the various types of epithermal deposits. The evaluation will be based on solving a practical work on examples of different deposits. The exam will be individual or in group, integrating the observations and discuss the results. The course is intended for graduate students of geology, advanced students in the career of Geology and professional geologists.
