Geology of the Butte Ore Deposit

Dr. John Dilles discusses the geochemistry of the porphyry Cu-Mo resource found at at Butte, Montana. The porphyry formed from dilute magmatic fluids that contained 1,000s of ppm Cu between 66 and 64 Ma, and at depths of ~8 km. The porphory is zoned from innermost Cu (Ag) ore; to mixed intermediate Cu (Zn, Ag) / Zn-MJn-Ag (Cu, Pb, Au) ore; to an outer Mn-Ag (Pb) ore that grades to barren quartz.

Expert-novice Differences in Geologic Field Mapping and Related Cognition

The geosciences are often characterized as a visuospatial field - that is, one in which success depends upon the ability to mentally manipulate, rotate, project, and bend objects. To what extent is the assumption of strong spatial visualization skills among geoscientists correct? This talk will discuss two studies that investigated geoscience expert and novice spatial visualization, both in laboratory experiments and in a novel field study.

Strategies for the Next Generation of Conservation: Lessons from a Life in Environmental Leadership

Successful leadership in the conservation community depends upon leaders with a vision who can engage collaborators in a transaction to create something of enduring value. Ideally, results are achieved in a win-win fashion with other stakeholders. However, a good leader must employ a broader range of tools.

Looking at Chemistry in Hard to See Places: Understanding Energy Conversion at 1400° Celsius

Solid oxide fuel cells (SOFCs) are promising devices for stationary and portable power and heat generation, because they can use complex fuels such as hydro-carbons, CO, and alcohols. Extreme, non-equilibrium conditions and high tem-peratures (≥ 700 ˚C) required for SOFC operation hamper efforts to understand the mechanisms of component degradation in SOFCs. This talk focuses on new insights into SOFC chemistry and the conversion of carbon-containing fuels (both hydrocarbons and oxygenated) into electricity, carbon dioxide and water, gleaned from a combination of techniques including electrochemical impedance spectroscopy, voltammetry, and vibrational Raman scattering.

Road Ecology: A Practitioner's Tale

Road Ecology is a relatively new sub-discipline of ecology that focuses on understanding the interactions between road systems and the natural environment. Wildlife crossings that allow animals to safely cross human-made barri-ers such as roads, are intended not only to reduce animal-vehicle collisions, but ideally to provide connectivity of habitat areas, combating habitat fragmentation. Wildlife mitigation strategies to improve the permeability of our infrastructure can include a combination of structures (overpasses/underpasses), at-grade crossings, fencing, animal-detection systems, and signage. One size does not fit all and solutions must be considered on a case-by-case ba-sis. Often, the feasibility of the preferred mitigation solution depends on a combination of variables including road geometrics, topography, traffic patterns, funding allocations, adjacent land use and landowner cooperation, the target wildlife species, their movement patterns, and habitat distribution. Joe and Deb will speak to the current road ecolo-gy practices in Montana and some real-world applications from the Department of Transportation.
