SUMMARY OF ANNUAL ACTIVITIES OF SEG - ST CHAP

During the last year, the SEG student chapter from Medellín has experienced an increase in members within the group, for which it has been strengthened. It currently has more than 20 active members, in addition to the indispensable accompaniment of approximately 5 university graduates and former members, who have continuously supported the group.

Our Academic Advisor continues to be Professor Oswaldo Ordóñez and this year we are proud to have a new Industry Advisor, whose name is Mauricio Castañeda. Both are very willing to help our group and with the activities carried out by the chapter.

REGULAR MEETINGS

Before the COVID-19 pandemic that occurred worldwide, the students belonging to the chapter met weekly in order to schedule activities to collect funds and share academic knowledge, for example, talks among ourselves to know mineral deposits and their characteristics around the world as well as other topics of interest about geochemistry, drilling, recognized mines, hydrogeology and more.

Figure 1. Weekly Student Chapter Meetings

Additionally, the SEG Student chapter actively participated in the events organized by the university to show the entire student population about the different student chapters belonging to the university. In this space, it was possible to share with other people what the chapter is, our mision and our goals as chapter, also we had the opportunity to exten invitation to new coming students interested enriching their knowledge in the area of economic geology.

FIELD TRIPS x GEOLOGICAL TRANSECT ACROSS THE CENTRAL AND WESTERN CORDILLERA IN COLOMBIA.

During this field trip, a 6-day journey was made, departing from the city of Medellín to the central-western area of the country. We had the opportunity to see the Bermejala stream, where the different alterations that occur in porphyry-type deposits can be observed, such as propylitic, quartz-sericitic, argillic and potassic.

Important rock formations from Colombia were seen, such as the Diabásico group (composed of mafic rocks of approximately 80 ma, columnar basalts and pillow lavas are observed), Dagua group (low-grade metamorphic rocks corresponding to phyllites of approximately 75 ma), Quebradagrande Complex (120 ma volcano- sedimentary rocks), Cajamarca Complex (240 ma metamorphic rocks), Ibagué batholith and sedimentary rocks of the Zarzal formation, La Paila formation, Payandé group, Honda group, formation, Gualanday formation, Luisa formation among others, in addition to lahars formed by volcanic activity and recognized faults such as Otú-Pericos, Honda, Palestina among others.

Additionally, different mines were visited, such as the Bolivar magnesite mine and CEMEX. On the other hand, La Colosa area was visited, which has a high gold potential but has not been exploited.

FUNDING RAISING PROGRAMS

The principal funds rising for the chapter are the organization of student’s chapter integrations, barbecues, raffles, and selling of chapter items as notebooks. We are saving all incomes for next activities.

On November 1st, 2019 we held a costume party to collect funds for the planned trip to Chile. We sold at least 100 tickets to university students and close people, in addition, we enjoyed a good night with all the chapter members and friends.

Figure 21. Costume party On the other hand, the university scheduled a fair on November 15th, 2019 so student chapters could collect funds. There, we prepared chorizos, chuzos and potatoes to sell. Fortunately, we sold everything we had prepared, and many people came to our stand to buy.

FUTURE PLANS

The student chapter had planned to go to Chile to meet world-class deposits, however, given the contingency generated by COVID-19, it had to be canceled, for which it is intended to reschedule this field trip for next year. We desire to visit the North and Central area of Chile and learn about how is the development of large scale mining, their impacts and environmental challenges, how is the geology and geodynamic setting and their relationship whit the mineralization, some of the geotechnical aspects and the general understanding of the full mining process.

Another idea is doing some field trips in Colombia, where we can visit large-medium- small scale mining and its environmental and social impacts. We are planning to continue doing some meetings and to prepare courses related with economic geology.

Also, we plan to get integrated with others student chapter in Colombia, such as: EAFIT, UIS, Pamplona and Universidad Nacional de Colombia, Bogotá. We plan to carry out joint field trips to different areas of the country, where mineralizations from different mineral deposits can be seen, such as porphyry, hydrothermal, VMS, and more.
