The Geosciences department is housed in the Marrs McLean Science Center, which was totally remodeled in 1995. Occupying most of the second floor of the building, the department has dedicated laboratory space for each of its activities. Twin laboratories for introductory classes each have abundant storage bins for specimen sets, and share a common storage area for specimen and map storage, and preparation of materials. Twin laboratories for upper division courses share a dedicated microscope room. Each faculty member has dedicated laboratory space adjacent to their office. Departmental space also includes the department office and conference room, a specialized computer lab for Geosciences, a sample preparation room, a student research lab and an equipment storage room and office for the department technician. The floor also includes two electronic classrooms equipped with complete audio-visual systems and computer projection.

Computing Facilities

Computer LabThe departmental computer lab includes 5 Dell Precision Workstations, flatbed and slide scanners, a 36"x48" high accuracy digitizing table and a laser printer. Additional workstations are located in the student research lab and the microscope lab. The department also has a color laser printer capable of tabloid sized output. In addition to servers run by the University's Information Technology Services, the department runs its own dedicated server with high speed RAID array, DAT tape drives and gigabit ethernet connection. Available software includes Microsoft Office Professional, Adobe Photoshop, Illustrator and Acrobat, ArcView 8.3 GIS software, ENVI remote sensing software, SPW seismic processing software and many additional applications for geologic, geochemical and geophysical data analysis.

Microscopy

Microscope LabIntroductory labs are equipped with both stereobinocular scopes and petrographic scopes. The upper division laboratories share a dedicated microscope lab equipped with Nikon sterobinocular scopes and binocular petrographic microscopes. Several scopes are equipped with trinocular heads for video and photographic work. The department has two digital microscopy systems including a Nikon DXM 1200 12MP imaging system with a dedicated PC workstation.

Sample Preparation

Sample PreparationThe department sample preparation facilities include two 24" slab saws, three 8" trim saws, Buehler PetroThin Thin Section System, Buehler Polimet I polisher, Buehler Vibromet2 vibratory polisher, IEC centrifuge, 3 Eberbach polishers, a Gilson sieve shaker, a Franz magnetic separator, a shatterbox and ceramic grinding vessels.
