Professor, Geology Program Coordinator
233 South Street
Helen Mango grew up in New York City, received her undergraduate degree in Geology from Williams College, and her Masters and PhD degrees in geology from Dartmouth College. Mango's graduate research involved studying the geochemistry of a large ore deposit in Guanajuato, Mexico. This deposit has been continuously mined for over 500 years for silver, gold, copper, lead and zinc. Mango's research used chemical principles and mineralogy to explain how the ore deposit formed. The focus of Mango's research now is on heavy metals (such as arsenic) in drinking water. This research has taken her as far away as Zimapan, Mexico, and as near as southwestern Vermont.
Mango has been teaching geology and chemistry at Castleton since 1991. Mango's courses include General Chemistry, physical and historical geology, geochemistry, energy resources and hydrogeology. Mango also teaches geology and chemistry to in-service and pre-service teachers. Mango has taken students to study the geology of Costa Rica (7 times) and Iceland (3 times). For fun, she gardens and she sings with several groups, including the Irish band Extra Stout, and the Spoon Mountain Singers.
