Covey, Aaron K (2008-12-06)Department: Earth and Environmental SciencesThis study investigates the effects of earthworm burrowing on arsenic mobility and speciation in soil. The use of roxarsone in the poultry industry as a feed supplement is an increasing anthropogenic source of arsenic. ...

Peters, Timothy James (2012-07-27)Department: Earth and Environmental SciencesThe mineral zircon (ZrSiO4) is a particularly robust geochronometer and arguably one of the most important minerals available to study the evolution of the Earth’s crust. Despite a high preservation potential, zircon grains ...

Belfanti, Sebastian Aldo Desveaux (2019-07-23)Department: Earth and Environmental SciencesThe volcanic-plutonic connection remains one of the most significant conundrums facing igneous petrologists. We have developed a methodology and initial basis of observation to identify volcanic events using information ...

Chattin, Archer Elleen (2015-07-17)Department: Earth and Environmental SciencesThe Bishop Tuff, a 0.76 million-year-old rhyolitic deposit in California, contains two crystal phases, described by Pamukcu et al. (2012). The first contains long-lived crystal grown over 5000+ years; the second consists ...

Weinman, Beth Anne (2010-08-13)Department: Environmental EngineeringElevated groundwater arsenic in Southeast Asia is a problem, as it is not unusual for wells spaced several meters apart from one another and drilled to the same depth to have dramatically different concentrations of arsenic ...

Tramontano, Samantha (2016-07-26)Department: Earth and Environmental SciencesIt is important to understand what triggers silicic eruptions because of the implications for modern-day systems. Here, we use phase equilibria modeling to determine to what extent magmas within the crust are induced to ...

Wallrich, Blake Marshall (2019-07-22)Department: Earth and Environmental SciencesIn this study, we take a multi-faceted approach to better understand silicic magmatism. The broad questions that we were aiming to address include: (1) How do magmatic systems and silicic magmas evolve through time following ...
