REGULAR MEETINGS AND LECTURERS

Since the chapter began in 2009 that members and former members

the chapter make presentations on economic geology in order to

teach undergraduate students about the different aspects in this area.

During the period from February to June of 2018, we focused on the

study of Cordilleran veins, Manto ore copper, Mississippi Valley Type

and Lamprophyre dykes.These types of deposits were visited during the

VI conference Metallogenic field "Luis Daniel Sáenz." In addition, we

have the participation of a former member of the SEG who gave us a

talk on basic concepts of structural geology applied to exploration.

In the second academic semester we focused on reinforcing basic

mineralogy and making an introduction to economic geology for new

chapter members. Likewise, during this period we concentrated on

studying the geochemistry associated with the genesis of the emeralds

in Colombia, afterwards we made a field trip to the western emerald

belt in order to consolidate the knowledge acquired during the

semester. In the last sessions of our academic meetings we will study

geochemical analysis techniques in order to apply them to our

research projects.

I . Mineralogy Workshops

On the 27th of August and 3rd of September of the current year we made two

mineralogy workshops, this events took place on mondays from 11am to 1pm in the

department of geosciences at the national university of Colombia in Bogotá, the

workshops proceeded as follows. The first session (27/08) was divided in a theoretical

part regarding mineral properties and a practical part in which we focused on

translucent mineral i.e. the rock-forming minerals.

Advertisements for the basic mineralogy sessions displayed in the geosciences department

and online. Left, focusing on rock-forming minerals and right focusing on ore-forming

minerals.

EXTRA-CURRICULAR ACTIVITIES

This first session developed according to schedule with an attendance of around 25

students, most of them in their freshmen and sophomore years; we divided this group

in 4 distinct tables, each with different related minerals, then, when the correct

identification of all the minerals in the table was achieved we switched the students

so they could learn and identify another group of minerals in a different table.

The students used all the basic methods of mineral identification i.e. color, luster,

streak, Mohs hardness, cleavage and fracture all explained on the theoretical part

of the session and during the practice; the students counted on diluted hydrochloric

acid and magnifying glasses for further testing.

First session of the mineralogy workshop.

The second session (03/09) dealt with opaque minerals i.e. ore-forming minerals,

oxides and sulfides, again the session was divided in two parts, the first one was

theoretical and concerned the basic properties of this minerals and a basic context

of deposits in which they are commonly found, with a focus on occurrences in

Colombia, the second part was the correct interpretation of different ore minerals

in hand specimen, with attention to commonly associated minerals.

The attendance for this session was bigger than the first one, with around 30 students,

again, divided in several tables each with related minerals. In this session we made

use of some recently collected specimens from the Yellowstone metallogeny

conference earlier this year, specially galena and stibnite.

Second session of the mineralogy workshop.

II. “Knowing something else about

minerals”

In the seedbed number 3, after the workshops of mineralogy, in which we worked

about: oxides, sulfides and silicates, with the intention of deepening into the physical

characteristics of each one them, we carried out an integration activity called

"Knowing something more about minerals" Through which we sought to encourage

students research. Each one had to perform a research of the characteristics of a

mineral that they chose, compile and reflect the information in a table that would

be exposed to all the participants, in that table, they had to write about: the physical

characteristics of the mineral (texture, hardness, color, exfoliation, density, crystalline

system, etc.), location, field (mineral deposit), deposits in Colombia and in the world,

utility, chemical composition, an image of the mineral and description of its genesis,

environments and other curious data.

The exhibitions were a success, the students showed interest in doing the research

and paid enough attention to each of the exhibitors. Some of the minerals that were

exposed were: Stibane, Realgar, Hessite, Molybdenum, goethite, hematite, native

gold, native copper, tyuyamunite, pyrite, arsenopyrite, sphalerite, emeralds, beryl,

pyrrhotite, bismuth, specular hematite, Hornblende, labradorite, Montmorillonite,

fluorite, tourmaline, chalcopyrite, etc.

After each exhibition, the pertinent questions were asked to clarify doubts, the

tables through which the exhibitions were made, were collected with the intention

of pasting them throughout the department of geosciences, to show everyone our

activity, and we are happy to say that participated between 20 and 25 students,

after the activity we went to the classroom and there, our president Camila Lopez

and our vice president Rafael explained the formation of some deposits such as

placer deposits, porphyries (Cu, Mo, Au) hydrothermal deposits of different sulfur,

and clarified terms such as: Epithermal, hypothermal, para-genesis, syn-genesis, and

other technicalities referring to permeability, depth, temperature, and

continentality. In conclusion we can appreciate the interest of the participants to

continue attending the seedbed and their willingness to participate in the proposed

activities.

INTRODUCTION

Colombian emeralds are in Cretacic sedimentary sequence in the eastern

cordillera in the west flank in Muzo, Quípama, La Palma, La Victoria, Otanche

and San Pablo de Borbur, also known as western belt.

The eastern belt which is formed by the towns as Ubalá, Chivor, Macanal and

Santa María. For that reason, we planned to visit the western and eastern

emerald belts in order to make a comparison in terms of mineralogy, fluids

dynamic, origin and structural controls which suggest a tectonic control

associated with regional and minor faults that are affecting the sedimentary

sequence as veins or extensional fractures.

The Student Chapter of the National University of

Colombia, Bogota, thanks the Society of Economic

Geologist, the Faculty of Sciences and the

Department of Geology of the National University

of Colombia, for giving us the means to learn and

share knowledge in the area of economic

geology.

In particular, we would like to thank the projects La

Marina and San Antonio for contributing to our

knowledge of Colombian emeralds, through

different activities developed during the

respective visits, which include presentations and

visits to the exploitation fronts.

We want to thank geologists Andrés Felipe

Gonzales Javier García Toloza, and Timoleon

Garzon for sharing their experience and resolving

our concerns regarding the complex genesis of

Colombian emeralds.

The student chapter organized and directed this visit to the western emerald belt

with the participation of 17 students and in collaboration with the SGA Student

Chapter. This short field visit was held on September 28, 29 and 30, during which

we had the opportunity to visit three different projects.

SUMMARY

• September 28:

We begin our field trip with an introductory talk on the regional geology,

geochemistry and genesis associated with the emerald deposits located in the

western belt. This talk was led by the Geologist and former president of the SEG,

Andrés Felipe Gonzales and the geologist Javier García Toloza who has

extensive experience in emerald certification and research.

After the introductory talk, we moved to the municipality of Pauna, located in

the department of Boyacá, four hours from the city of Bogotá.

September 29:

During the morning we visited the "La Marina" project, in which an unusual

mineralogical association of Euclasa- Aguamarina-Apatite has been reported.

We had the opportunity to discuss with project geologists and artisanal miners,

later they explained about the structural controls and some strategic exploration

tips.

• September 30:

During this day, we focused on performing field work in order to understand the

regional geology like lithology, structures and geomorphology by mapping

activities, the we visited a project located in Coscuez -Boyaca.

”

Since 2013 the SEG Student Chapter UNAL - Bogotá had been organizing the

Metallogenic Field Conference “ Luis Daniel Saenz" in which both, students and

professionals had the opportunity of visit and learn about different world class

deposits of different kinds. Since 2014, William X. Chávez and Juan Carlos Molano

have directed the Conference.

This year, we decided to visit projects, which we could learn about different

deposits as lead and zinc remplacement carbonates and lamprophyre

dikes.This field trip gave us the opportunity to make comparisons between

deposits which we have in our country and, identifying differences between

deposit models. In the end, we realized the importance of stratigraphy, structural

geology and historical geology to understand these deposits.

Professionals of Colombia, Perú and Nicaragua joined us, in the most diverse

edition of the conference so far.

Finally, we closed our field trip with a visit to Yellowstone Caldera in Yellowstone

National Park in the Western United States. This visit gave us the possibility to

understanding hydrothermal and geothermal activity. For more information

about this incredible field trip, go to the field trip report 2018.

SEG 2018 Conference in Keystone, CO, USA

Metals, Minerals, and Society

During the month of September, one student of the student chapter, Carlos José

Charry Celis presented the summary of his work. He was accepted to participate

in the SEG Conference 2018, which was held in Keystone. He has the opportunity

to attend a great variety of conferences about ore deposits, updates on the

deposits that have been discovered at present, the techniques and new

chemical analyze that had being done, and the deposits types that have

become increasingly important in modern times.

Of course, it was a great moment to continue making friendship with Latin-

American students.

FUTURE PLANS

We really have a lot of future plans¡ At this moment, we have

different topic to carry out.

We will continue with our academic conferences to increase our

knowledge about ore deposits and economic geology. Also, we

will continue doing our mineral fairs: we want to expand it and

reach more people who like minerals as much as us¡

And in 2019, we will make our 7th Metalogenic Field Conference

"Luis Daniel Sáenz" our most important field trip of the year.
