Mary Herrmann-Foley, MBA, returns to campus as the EPSSI Seminar guest speaker on Monday, October 23, 2023, from 4 – 5 p.m. in M&M room U113. Mary completed her Bachelor’s Degree in Geological Engineering at Michigan Tech in 1983. She continued her education at the University of Houston, earning her master’s in business administration in international finance in 1985. Currently, she serves as Manager of Central Support PetroSigns SSW application at Shell. Last fall, Mary was inducted into the Academy of Geological and Mining Engineering and Sciences. We are excited to welcome her back to campus once again!
In her talk, Role of Subsurface Engineering and Geology in the Energy Transition World, she will discuss the essential role of subsurface engineering and geology in the changing world of energy transition.
From the abstract: The world is in the midst of the first “truly global energy crisis,” the International Energy Agency (IEA) said in its World Energy Outlook in October 2022. It’s multidimensional and comes with the challenge of global warming and the need to reduce/eliminate CO2 emissions. We are all experiencing the impact of rising CO2 in the atmosphere: ocean levels rising, more intense storms, and increasing temperatures with corresponding implications on us and the environment around us. Conflicting pressures linked to continued high-energy demand, the need for energy security, and the imperative for reducing CO2 emissions are driving unprecedented renewable energy growth. This presentation will touch on the challenges related to these conflicting pressures and how existing and start-up energy companies are addressing some of these challenges through numerous renewable energy and carbon sequestration options, mainly focusing on the crucial role subsurface engineering and geology can play in this journey. Highlights of Michigan’s current situation and related business opportunities will also be discussed.
All are welcome to attend.

Title: Integrating LiDAR, Aeromagnetic, and Geological Field Data to Identify Structural-Lithologic Elements Within the Archean Carney Lake Gneiss Complex
Abstract: The Archean Carney Lake Gneiss Complex (CLGC) is a suite of rocks on the southern margin of the Superior Province and within the Minnesota River Valley subprovince. It is one of many gneissic domes in Michigan, Wisconsin, and Minnesota whose complex geology is poorly understood due to a previous lack of economic interest in gneissic terranes and significant challenges to their investigation. As a consequence, the CLGC and other gneissic domes in the region are represented on geologic maps as undifferentiated masses surrounded by better-defined and understood Paleoproterozoic supracrustal rocks and igneous intrusions. Within the last ten years, however, the United States has identified an urgent need to find new sources of critical minerals to sustain and grow the nation’s technology and defense industries, which has renewed interest in these very old and complex rocks. Under the Earth Mapping Resources Initiative (Earth MRI) of the U.S. Geological Survey, the CLGC and surrounding Paleoproterozoic rocks have been remapped to update geologic interpretations and to assist in identifying potential mineral systems in the region. Mapping of the CLGC was accomplished using traditional techniques combined with satellite-based phone applications and differential GPS devices to navigate in dense vegetative cover, to obtain accurate coordinates of field sites, and to collect geologic data at outcrops. As a further aid to ground mapping, high-resolution LiDAR and aeromagnetic data were analyzed to determine topographic and magnetic patterns and textures that potentially reflect structural-lithologic domains within the CLGC.
Integration of the new geologic field data with features and patterns identified on LiDAR and aeromagnetic maps allows definition of three domains within the CLGC: (1) a poly-deformed, mostly felsic gneiss with folded and sheared banding; (2) a meta-igneous, plagioclase-dominated gneiss with poorly expressed banding; and (3) a meta-sedimentary gneiss with thin well-developed banding and local relict sedimentary textures. Outcrop mapping also reveals the widespread occurrence and great variety of younger felsic and mafic intrusions that were not fully appreciated by earlier mappers. Data integration has allowed better definition of geologic unit contacts around the margins of the CLGC and within some Paleoproterozoic metasedimentary units, which updates knowledge about the Sturgeon Quartzite to the northeast and the Vulcan Iron Formation to the south. Although some analytical work is ongoing, such as radiometric age dating, the integrated mapping effort has identified between five to eight tectonomagmatic events that have affected the region, plus a number of sedimentary cycles. The abundance of processes that have affected the area provides multiple opportunities for concentration of mineral deposits that could be attractive for future exploration efforts. The data integration approach developed for this thesis project should be useful in identifying structural-lithologic domains within enigmatic Precambrian gneiss domes elsewhere in the region and globally.
On Friday, July 21, Jordan Ewing successfully defended the research for his doctoral degree in computational science and engineering.
Advised by Thomas Oommen, with Laura Brown, Stanley Vitton, and Paramsothy Jayakumar as committee members.
Title: Remote Sensing Approach for Terramechanics Applications Utilizing Machine and Deep Learning
Abstract: Terrain traversability is critical for developing Go/No Go maps, significantly impacting a mission’s success. To predict the mobility of a vehicle over a terrain, one must understand the soil characteristics. In situ measurements performed by soldiers in the field are the current method of collecting this information, which is time-consuming, are only point measurements, and can put soldiers in harm’s way. Therefore, this study investigates using remote sensing as an alternative approach to characterize terrain properties.
This approach will explore the relationships between electromagnetic radiation and soil types with varying properties. Optical, thermal, and hyperspectral sensors will be used to collect remote data and compare it against ground truth measurements for validation. Machine learning (linear, ridge, lasso, partial least squares, support vector machines, and k nearest neighbors) and deep learning (multi-layer perceptron and convolutional neural network) algorithms will be used to build prediction models.
Results showed that soil properties such as soil gradation, moisture content, and soil strength measured by a geogauge and averaged cone penetrometer for 0–6” and 0–12” (CP06 and CP12) can be estimated remotely. Deep learning provides the best models for estimating terrain characteristics compared to machine learning. It is shown that this method can produce much finer spatial resolution coverage than traditional geospatial point-based interpolation approaches and yield a higher prediction accuracy. Predictions maps can be used to generate threshold-based Go / No Go maps using a vehicle cone index or as a cost map for vehicle performance. A Polaris MRZR vehicle was used to test the application of these prediction maps for mobility purposes, and correlations were observed between the CP06 and rear wheel slip and CP12 and vehicle speed.
This study demonstrates the potential of using remote sensing data for more rapid and finer spatial resolution predictions of terrain properties with higher accuracies compared to traditional in situ mapping methods implementing machine and deep learning algorithms. The remote sensing approach allows the generation of Go/No Go and vehicle cost maps and, most importantly, provides a safe alternative to keep soldiers out of harm’s way.
It takes a lot of hard work, determination, and sacrifice to complete a college degree, and you have done it. Congratulations on your achievement!
The Department of Geological and Mining Engineering and Sciences offers our sincerest congratulations on your well-deserved success! This is a momentous occasion and a testament to your dedication and perseverance. You should feel proud of your accomplishments and the bright future that awaits you.

Brendan Harville, applied geophysics junior advised by Dr. Greg Waite
Title: Seismic Amplitude based Lahar Tracking for Real-Time Hazard Assessment
Abstract: Lahars are strong debris flows or mudflows caused by volcanic activity and also non-volcanic activity in the form of heavy rainfall. They can cause extensive damage to the surrounding environment as well as local communities and infrastructure. The goal of this project is to create a fully automated lahar tracking tool for hazard risk mitigation. Lahars transmit a long-lasting, high frequency tremor signal that is observable in waveform data from seismic stations (Kumagai et al. 2009). This research project plans to use an established network of seismic stations on the slopes of Volcán de Fuego, the resulting tremor signals, and the modified technique presented by Kumagai et al. (2009) to track the origins of individual lahars in real-time.
Espree Essig, geology Ph.D. student advised by Dr. Chad Deering
Title: Analyzing the effects of heavy metals on vegetation hyperspectral reflectance properties in the Mid-Continent Rift, USA
Abstract: In a society focused on global sustainability, metals including copper, nickel and cobalt have become fundamental. Despite increasing demand, deposit discoveries have plummeted owing largely to dwindling ‘low-hanging fruit’ that are near-surface. With this challenge, exploration for buried and vegetation-covered mineralization has become more relevant. However, short of direct geological observations, a proxy correlating mineralization with surficial patterns is necessary. The aim of this study is to analyze the effects of heavy metal enrichment on the hyperspectral reflectance properties of vegetation near polymetallic (Cu- Ni-Co- PGE) mineralization in the Duluth Complex, northeastern Minnesota. This natural laboratory is regionally representative of the mineralization perspective across the Lake Superior region, where vegetation, wetlands and glacial till have impacted exploration efforts and success. This pilot-study investigation will resolve the feasibility of vegetation-based hyperspectral methods to detect poorly exposed deposits in the Lake Superior region.
Caleb Kaminski, geophysics MS student advised by Dr. Aleksey Smirnov
Title: Investigation of Ground-Penetrating Radar Interactions with Basaltic Substrate for Future Lunar Missions
Abstract: Ground-penetrating radar (GPR) is a suitable tool for interplanetary rover exploration on the Moon. Anticipated future lunar missions sponsored by governmental and private organizations alike are making headway toward a breakthrough in planetary science. Understanding the geological and geophysical properties of the lunar regolith is paramount for the beginnings of permanent structures on the lunar surface. The Moon’s surface is primarily composed of basalt, a common[AS1] volcanic rock found here on Earth. My proposed research will focus on the effect of basaltic grain size on dielectric permittivity [AS2] and electromagnetic (EM) signal velocity, using 500 MHz and 1000 MHz GPR antennas. My hypothesis is that changes in the grain size of basalt from silt to small boulders will affect the EM properties of the material. Gaining a further understanding of the interactions between basalt and EM waves will benefit future engineering and mining efforts that involve the lunar regolith.

Title: Structural Characteristics of the Keweenaw and Hancock Faults in the Midcontinent Rift System and Possible Relationship to the Grenville Mountain Belt
Abstract: Since the mapping of the Keweenaw Fault in the 1950s, significant advances in mapping technology and knowledge about fault systems have been made. This project will remap the hanging wall and footwall of the fault using advanced geospatial technology to reexamine the kinematics of the Keweenaw Fault in the Laurium and Hancock Quadrangles, Michigan.
Paola Rivera Gonzalez, geology Ph.D. student advised by Dr. Kari Henquinet
Title: Impacts of La Canícula (“Dog Days of Summer”) on agriculture and food security in Salvadoran communities in the Central American Dry Corridor
Abstract: A rising population, demand for natural resources, and a changing climate are exacerbating vulnerabilities globally and elevating the priority to mitigate risks. The impacts of these changes on agriculture in rural communities jeopardize regional food security and water accessibility. In the Central American Dry Corridor, La Canícula or the “Dog Days of Summer”—a short-duration dry period during a six-month-long rainy season—is expected to lengthen and worsen in the next decades (Anderson et al., 2019), bringing more frequent drought to countries like El Salvador. This study examines the changing canícula and its effects on rural, eastern El Salvador using ethnographic methods and physical measurements—satellite-based data of precipitation, soil moisture, and temperature—to correlate geophysical changes to farmers’ experiences, adaptation practices, and decision-making. Integrating local knowledge and hydrometeorological conditions highlights the most affected areas in agricultural communities, documents existing adaptive strategies, and may inform future adaptive planning.

Title: Lift and Launch the Western U.P.: SOLID Start (Science, Oral Language, and Literacy Development from the Start of School) for First and Second Grades
Abstract: Early elementary students in the Western Upper Peninsula (WUP) have limited access to STEAM learning experiences. The WUP comprises largely remote, rural communities and is home to two Sovereign Tribal entities. WUP communities have historically lacked equitable educational resources because of isolation and poverty. Lift and Launch the Western U.P will increase student engagement in STEAM by coordinating a Pre-college Education program that includes multi-district adoption of the NGSS-aligned curriculum, SOLID Start (Science, Oral Language, and Literacy Development from the Start of School). Additionally, an educational Teacher Training program will integrate place-based and career development activities into the curriculum highlighting unique attributes of the WUP. The new professional learning program would be ongoing, including summer field experiences and school year sessions, designed to increase educators’ pedagogical content knowledge. The innovative and collaborative approach would embed regionally significant examples and community partnerships into the SOLID Start curriculum.
