Geoscience, along with other scientific disciplines, is being increasingly challenged on how it can best confront key global challenges, such as climate change, food insecurity, biodiversity loss, human conflict and migration, and persistent poverty. But its traditional association with exploitation of the planet’s natural resources for energy and materials links it with contemporary concerns around unsustainable human practices, arguably fueling a growing disenchantment that is most evident in declining enrollment in university geoscience courses in many countries. Therefore, a fresh re-framing of the geoscience’s relationship to society would seem to be urgently needed. In response to this need, we introduce …

Preliminary Study Identifies Possible Sources For Nephi's Ore

Insights: The Newsletter of the Neal A. Maxwell Institute for Religious Scholarship

The efforts begun by Warren and Michaela Aston to identify important sites along the Lehi trail eventually evolved into a FARMS project and exploration to Southern Oman's Dhofar region in 1992. The remote area of Wadi Sayq in that region has been identified as a location that appears to meet all of the criteria one can infer from the text of the Book of Mormon for the coastal site named Bountiful by Lehi and his family, where they lived while building a ship for their ocean crossing.

Improving Xrd Analysis With Machine Learning, Rachel E. Drapeau

Theses and Dissertations

X-ray diffraction analysis (XRD) is an inexpensive method to quantify the relative proportions of mineral phases in a rock or soil sample. However, the analytical software available for XRD requires extensive user input to choose phases to include in the analysis. Consequently, analysis accuracy depends greatly on the experience of the analyst, especially as the number of phases in a sample increases (Raven & Self, 2017; Omotoso, 2006). The purpose of this project is to test whether incorporating machine learning methods into XRD software can improve the accuracy of analyses by assisting in the phase-picking process. In order to provide …

Identification Of Aquitard Breaches Using Electrical Methods And Borehole Data In Shelby County, Tennessee, Md Rizwanul Hasan

Electronic Theses and Dissertations Archive

Inter-aquifer exchange of poor-quality water through hydrogeologic windows or breaches (with absent or thin low-permeability layer) in confining units can affect the water quality of confined water-supply aquifers. Identifying breach location and geometry is essential for protecting and managing water resources. Previous studies provide evidence for 16 breaches in the upper Claiborne confining unit (UCCU) overlying the Memphis aquifer, a regionally important water-supply aquifer, in Shelby County, Tennessee. Researchers suggest that the breaches may result from the paleo-channel incision during the Eocene sea-level fall and the Quaternary incision by western Tennessee tributaries to the Mississippi River. This study utilizes electrical …

Revisiting Great Basin Bristlecone Pine (Pinus Longaeva) In The Stansbury Mountains, Utah, David R. Burchfield, Otto W. De Groff, Matthew F. Bekker, Stanley G. Kitchen, Steven L. Petersen

Western North American Naturalist

Great Basin bristlecone pine (Pinus longaeva D.K. Bailey) presence in the Stansbury Mountains of north-central Utah has been reported prior to the year 2020, but these reports lack adequate population characterization and the delineation of distinct stands of trees. In summer 2020, we identified and documented the presence of 5 separate stands of bristlecone pine in the Stansbury Mountains. These stands are removed from the nearest bristlecone populations in other mountain ranges by a distance of approximately 120 km; as such, they represent a unique outlier population of the species. We used GPS data to create a geographic information …
