How Geology Becomes Archeology:
Pitt Geology Professor Reveals Pre-Incan Silver Industry in Bolivean Andes.

PITTSBURGH--Applying a technique never used in South America, University of Pittsburgh Assistant Professor of Geology Mark Abbott has found evidence that a major pre-Incan silver industry began in 11th century Bolivia, 400 years earlier and on a much larger scale than previously thought.

Geologists Abbott and coinvestigator Alexander Wolfe of the University of Alberta, Canada, who study lake sediments, will report their findings Sept. 26 in Science.
