A spectroscopic approach for inferring charcoal concentrations and fire history from lacustrine sediments
DownloadFall 2013
Current wildfire activity highlights the precarious ecological state of for- ests owing to the combined effects of climate change and management practices. Because the analysis of long-term fire frequency from sedimentary archives is critical to understanding fire dynamics, there is a continuous...

A new Early Eocene (Lostcabinian) mammal assemblage from the Main Body of the Wasatch Formation, Northern Green River Basin; The Pinnacles, Sweetwater Co., Wyoming
DownloadFall 2013
Taphonomy of fluvially deposited microvertebrates and systematic paleontology of the Pinnacles buttes in the northwest Great Divide Basin is examined. The Pinnacles buttes contain an early Eocene mammal assemblage of over 900 cataloged specimens from several prolific University of Michigan...

A new approach to understanding the origin of Fuerteventura, Canary Islands (Spain): A U-Pb, Hf and O isotope and minor- and trace- element detrital zircon study
DownloadSpring 2019
The Canarian Archipelago contains seven islands proximal to the African continent and High Atlas Mountains. The origin and magmatic evolution of these islands has been a contentious issue for several decades. This particular archipelago is unique because three of the islands (Fuerteventura, La...

A Multidisciplinary Investigation on the Influence of Archean Seawater Composition and UV radiation levels on the Survival and Evolution of Early Microorganisms
DownloadFall 2014
Life evolved in the oceans nearly four billion years ago, but the environmental conditions surrounding its evolution remains poorly understood. While Archean seawater (2.5 to 3.8 Ga) provided ancient microorganisms with the bioactive trace metals needed to sustain their metabolic requirements, it...

A Model for the Solubility of Minerals in Saline Aqueous Fluids in the Crust and Upper Mantle
DownloadFall 2018
Quantifying and predicting the dissolution of minerals in complex (multicomponent) aqueous fluids across wide ranges of P-T space is critical for interpreting geologic processes that involve water-rock interactions in the Earth’s crust and upper mantle. Here, we define a new thermodynamic model...

A Model for the Solubility of Anhydrite in H2O-NaCl fluids from 25 to 800 °C, 0.1 to 1400 MPa, and 0 to 60 wt% NaCl: Applications to Hydrothermal Ore-forming Systems
DownloadFall 2021
Anhydrite (CaSO4) is a common gangue mineral in hydrothermal ore-forming systems, though currently there is no robust numerical model for the solubility of anhydrite in H2O-NaCl hydrothermal fluids. Here, we present a thermodynamic model for the solubility of anhydrite in saline aqueous fluids...
