Report on the UNESCO-SEG International
June 1-14, 2003, Quito, Ecuador
Success drives Expansion - Course to be offered outside Ecuador
Lluís Fontboté (SEG 1990 F)
The 2003 UNESCO-SEG Metallogeny Course held at the Universidad Central de Ecuador on June 1-14, 2003, was attended by 55 participants, including 37 non-Ecuadorians (Peru, Argentina, Chile, Colombia, Mexico, Cuba, and Brazil were represented, in order of numbers that Latin American Ph.D. students currently in the United States, Canada, and Australia). Twenty-eight attendees received support from the Swiss Agency for Development and Cooperation (SDCKFPE), UNESCO, SEG and the Universidad Central. The group was a good mixture of industry (17), academia (28), and geological surveys (10).
Topics covered in the 2003 edition included tectonomagmatic controls on porphyry and epithermal deposits in the central Andes (Jeremy Richards, University of Alberta, 2003 SEGInternational Exchange Lecturer); epithermal deposits (Jeff Hedenquist, Colorado School of Mines), structural controls on epithermal deposits (Peter Lewis, Vancouver), overview of lead isotope signatures and metallogeny of Ecuador (Massimo Chiaradia, Leeds, UK; Bernardo Beate and Arturo Eguez, Universidad Politécnica, Quito); the Nambija gold skarns (Lluís Fontboté, Agnès Markowski, Jean Vallance, Geneva, Switzerland, and Massimo Chiaradia, Leeds, UK), and the Zaruma-Portovelo intermediate sulfidation gold deposits (Richard Spencer, IAMGOLD, Quito). Participants received, in addition to the printed course notes, a CDROM with most of the presentations in Powerpoint and as pdf files.
After six days of classroom sessions in Quito, 33 participants attended a one-week field trip to the Nambija gold skarns, the Zaruma-Portovelo gold deposits (where we were host of IAMGOLD), and the Au-rich VHMS deposit of La Plata, currently owned by Sultana del Condor Minera. The field guide (http://www.unige.ch/sciences/terre/research/Groups/mineral_resources/latinometal/quito03/quito03_guide.html), including abundant graphics, is accessible at the course website.
The metallogeny course is about to undergo major changes. It will now travel around Latin America, so that training available in this part of the world will be even more extensive. Other benefits will be the access to a larger pool of lecturers as well as many new field areas to visit. In addition, there should be opportunities for increased support from companies located in each host country, not to mention support from rotating host institutions. The designated 2004 international course coordinator, Fernando Tornos (IGME, Salamanca, Spain), is in contact with several centers of economic geology in the southern part of the region. Expressions of interest in hosting the UNESCO-SEG Metallogeny Course for future years are welcome.
As coordinator of the 2003 edition, I would like to especially acknowledge the Universidad Central de Ecuador for its 22 years of hosting, in Quito, the "Curso Internacional de Postgrado en Metalogenia," supported by UNESCO (and since 1999, also by SEG), as well as all instructors, sponsors, and companies that have made the course possible. Last but not least, I would like to thank the 55 participants for the interest and enthusiasm expressed by their endurance of the very long classroom program (sessions from 8 a.m. to 7 p.m.!).
