Science professor documents history of the Andes Mountains with presentation, Dec. 4

Dr. Johan P. Erikson, assistant professor of Environmental Sciences at Saint Joseph’s College of Maine, is holding a Dec. 4 lecture that uncovers the changing nature and the forces that alter the face of South America’s Andes Mountains. “Relating growth of the Andes mountain range in Venezuela to erosion and eventual sediment accumulation: a field and laboratory geologic research project” is part 7 of Saint Joseph’s Centennial Faculty Lecture Series.

Taller but narrower than the Rocky Mountains, the Andes in northern South America have a story to tell about the different ways that mountain ranges grow. Dr. Erikson will highlight how river sands, radioactive elements and the Earth’s magnetic field are used to decipher 15 million years of mountain growth and erosion.

Dr. Erikson engages the Saint Joseph’s College community as an instructor of chemistry, climate change, environmental geology, hydrology and studies of the Gulf of Maine environment. He has authored or co-authored more than 20 conference presentations and numerous publications.

The presentation takes place Dec. 4 at 7 p.m. in the Viola George Auditorium in Harold Alfond Hall at Saint Joseph’s Standish campus. The 30-minute presentation will be followed by 30 minutes of Q&A. The event is free and open to the public.
