Geology Department Facilities and Equipment

Facilities

The Geology Department occupies offices and research laboratories fully equipped with up-to-date equipment for nearly all standard methods of geology, geophysics, geochemistry, and hydrology. Among facilities and equipment available for research are the following:

Rock and Geochemical Facilities
