  3. Christine Burrill

    PhD — 2021, Geology, New Mexico Tech
    Dissertation:
    Testing global scaling models for cosmogenic geochronology and developing a more detailed history of Mount Erebus and Mount Waesche volcanoes
    Advisors:
    Phillips, Heizler, Kyle, Zimmerer
    The goal of Christine’s work is to demonstrate which cosmogenic production scaling model produces correct numerical ages for multiple lava flows on Mount Erebus, Antarctica by comparing 36Cl and 3He exposure ages to 40Ar/39Ar-produced ages. The secondary goal of the project is to test whether cosmogenic nuclides should be scaled individually or uniformly by measuring the 3He/36Cl ratio of lava flows from a range of elevations on Mount Erebus. In performing these tests, we will also have the data to establish the first local cosmogenic nuclide calibration site in Antarctica, which will be applicable to broader areas of research. 40Ar/39Ar ages from numerous lava flows on the flanks Mount Erebus, most of which have never been sampled before, will hopefully help us better understand the evolution of the volcano. Similarly, 40Ar/39Ar ages from lava flows on Mount Waesche will help us understand whether there is a pattern to locations of vents, compositional changes, or frequency of eruptions and if there’s any connection between volcanism and tectonics or ice sheet levels.

  6. Deusavan Costa Filho

    PhD — (expected) 2024, New Mexico Tech
    Dissertation:
    Partitioning of REE between fluid-calcite and -apatite at hydrothermal conditions
    Advisors:
    Gysi
    This research is part of a NSF CAREER funded project to A. Gysi. Deusavan will carry out laboratory experiments and measure the partitioning of REE between aqueous fluids and hydrothermal minerals including apatite and calcite up to to 300 °C. The experiments will be carried out in our new Ore Deposits and Critical Minerals experimental laboratory and aim at synthesizing REE-doped crystals. Deusavan will also react natural calcite crystals with hydrothermal aqueous fluids up to 250 °C to study fluid-mineral interface reactions. Part of Deusavan's research will be to develop a thermodynamic model for simulating the causes of REE variations observed in natural calcite veins and apatite in different hydrothermal-magmatic ore deposits.

  7. Brandon Dennis

    — Stephen Wells Bright Star Intern
    Bachelors — 2022, Computer Science, New Mexico Tech

    In his fourth year of Bright Star funding, Brandon is working with the Bureau IT group, mainly focusing on generating web forms to replace Microsoft Access forms. He also continues assists Chris Armijo on various support challenges. In past years, Brandon played a key role in migrating a database on a USGS-funded research project in the Gallinas Mountains from MS Access to MS SQL Server. This change helped eliminate many of the challenges associated with multiple researchers managing data in a MS Access database. The process developed for the Gallinas migration is being tested on other MS Access databases within the Bureau, specifically one focusing on New Mexico Mines. Brandon will be assisting Mark Leo-Russell in setting up the database for DOE-funded REE in Coal project. Brandon is also working on a project to evaluate software tools to generate web forms for simple data entry and edit functions. The goal is to develop a documented process for generating web forms which could be used in place of MS Access for data entry and edits where appropriate.Brandon also was recently first author on a paper entitled: Comparative Analysis of Object Visualization Tools with Respect to Their Use in Education

  8. Alex Duff

  9. Anne Dunn

    — Stephen Wells Bright Star Intern
    Bachelors — (expected) 2024, Materials Engineering, New Mexico Tech

    In her Bright Star project, Anne Dunn is working on molecular dynamic simulations of quartz breakage, resulting from an applied shear stress, in an aqueous environment. Water molecules affect the Si-O bonds at the outer quartz surface, through solvation, and along the fracture surface (possible cleavage surface) as the fracture propagates through the quartz structure, the process known as stress corrosion.

    Most of us were taught in introductory geology that one of the integral properties of quartz is conchoidal fracture (and the absence of cleavage). It turns out that this is not exactly true. Rapid breakage does result in conchoidal fracture, but quartz can exhibit cleavage and it is not uncommon in samples found in certain types of geologic environments.

    It has been hypothesized that slow fracture propagation in the presence of an aqueous fluid, through the process of stress corrosion, may lead to the development of quartz cleavage planes. This video, courtesy of Alan Hart, shows a particularly striking example. This is a quartz crystal that grew from a hydrothermal fluid into an open space in a vein (in Hot Springs, Arkansas). During the growth process the crystal was cleaved and the two pieces were displaced but not separated. Continuation of quartz precipitation along the cleavage plane “healed” or recombined the two pieces into what is now a single crystal again.

  18. Stephanie Roussel

    Masters — 2021,
    Thesis:
    Riparian evapotranspiration recovery post-fire: using diurnal groundwater fluctuations and remote sensing to quantify phreatophyte interactions in a disturbed landscape
    Advisors:
    Newton, Cadol, Rinehart
    Stephanie's project will document the recovery of riparian vegetation using continuous groundwater monitoring at wells installed by the Interstate Stream Commission along two transects, one along the southern border of Bosque del Apache Wildlife Refuge and one near the ghost town of San Marcial. The study will also monitor vegetation recovery using repeat aerial imagery surveys collected by drone. The overlapping images will be processed at the Bureau of Geology to create orthomosaic and greenness maps. These maps will be correlated to lower resolution satellite images and used to estimate vegetation evapotranspiration rates, the rate at which plants release water to the atmosphere. The project will support the important work done by land managers in New Mexico.Stephanie received the New Mexico Geological Society’s (NMGS) 2020 Frank E. Kottlowski Research Award worth $2,500, for the highest quality research proposal of all those submitted to the society for the February 2020 proposal deadline.
