Students should register for Earth and Atmospheric Sciences 4170: Geologic Field Mapping in Argentina, for four credits
The course consists of lectures in Buenos Aires and field exercises in the Sierras Pampeanas, Precordillera, and Main Cordillera Ranges of the Argentine Andes. Classes and field exercises are held in combination with students, faculty, and staff from the University of Buenos Aires (UBA).
The field area is marked by spectacular rock exposures and superb examples of geologic phenomena in an active tectonic environment.
The first part of the course is based on field exercises that include mapping of recently active faults, Precambrian metamorphic rocks including a Precambrian ophiolite, Paleozoic to Tertiary sedimentary rocks, and Tertiary volcanic rocks. As a principal exercise students will construct a geologic map and structural cross-section across the Precordillera range.
The second part of the course includes two mapping projects and a four-day field trip with study exercises in the adjacent Frontal and Main Andean Cordilleras. The final portion of the course is optional for UBA students.
