Established in 2015, the Mackay School of Earth Science and Engineering Microbeam Laboratory houses two state of the art JEOL scanning electron microscopes (SEM), a field emission SEM and an easy to use portable tungsten-filament SEM. The field emission SEM has an Oxford energy dispersive spectroscopy (EDS) and electron backscatter diffraction (EBSD) systems and a Deben cathodoluminescence (CL) detector. The tungsten-filament SEM has low-vacuum capabilities, which allows for examination of biologic and other moist materials. The lab is transforming research in the Earth Sciences at Mackay and within the College of Science and is being used increasingly by other departments and colleges at UNR. The machine is also utilized by entities outside UNR, fostering cooperation and collaboration among UNR, the city of Reno, greater Nevada, and researchers throughout the world. Our mission is to make the Mackay School of Earth Science and Engineering Microbeam Laboratory the microscopy lab of choice for the western U.S.


Gold Ore Chip

Combined secondary/backscattered electron image of a chip of Carlin-type gold ore from the Barrick Gold’s Turquoise Ridge mine in Nevada. ┬áCompletely decalcified limestone-mudstone that is now composed of hydrothermal quartz (Q), kaolinite (K), and fine-grained gold-bearing arsenian pyrite (P), the main site of gold in Carlin-type gold deposits in Nevada.
