Elliz McClelland Interns for EarthScope and Presents at the American Geophysical Union Annual Meeting

Published
By

This summer, Elliz McClelland interned in the URISE (Undergraduate Research Internships in Seismology) program, funded by EarthScope (formerly known as IRIS). This internship experience gave them professional research experience, guidance about graduate schools, and the opportunity to work with an institution they’d like to work at during their career. As part of their internship experience, they will also present at the annual national American Geophysical Union (AGU) meeting in December 2023, a completely new experience for them.

During Elliz’s internship, they conducted research into a volcanic caldera using geophysics in New Mexico. Elliz worked under the mentorship of the United States Geological Survey and spent part of their summer working in the USGS office in Denver, Colorado. This internship was a multi-faceted experience where they had the opportunity to do a lot of traveling. Elliz spent their first couple of weeks performing fieldwork in New Mexico in their study area, then moved into Denver to work at the USGS office. They were also lucky enough to work on a separate USGS project where they traveled to Hawaii to help their mentor conduct field research. Their summer was full of new experiences and cultures!

The URISE internship was highly targeted toward providing research experience and preparation for graduate school. While Elliz intends on taking a least one gap year before attending graduate school, the information the internship coordinators provided them about graduate school was instrumental in making their decisions about furthering their education. 

When reflecting on the value of the URISE internship, Elliz says, “For my needs, this internship was also immensely useful in determining my career path. I ‘put my boots on the ground’, so to speak, working directly with the USGS under a position I might like to hold myself in the future. My summer experience really confirmed for me that I love doing field work and I would enjoy working for an institution like the USGS.”

In December, Elliz presented their work at the AGU national conference in San Francisco, California. This conference is one of the biggest Earth Science conferences in the nation and is an excellent opportunity for students to meet potential employers, experience the professional research conference environment, and network with fellow geoscientists. For more details about Elliz’s internship experience and the research they conducted, you can visit their summer blog at URISE. Elliz would also like to highly recommend this internship to any geoscience students with an interest in research and geophysics. Anybody can apply and prior geophysics experience is not required! You can stay updated about internship applications at URISE.

Murchek Successfully Defends Geophysics Ph.D. Research Proposal

Published
By

Jacob T. Murchek presented his doctoral research proposal defense on Friday, December 1, 2023. Advised by Dr. James DeGraff, with Dr. Benjamin Drenth, Dr. Jeremy Shannon, and Dr. Aleksey Smirnov serving as committee members. 

Murchek pictured collecting geophysical data across the Keweenaw Fault using the Lacoste Romberg Model G Gravity Meter and the Trimble differential GPS unit to create better constrained models of the subsurface geology crucial to refine the history of the Midcontinent Rift System and copper mineralization.

Title: Integration of Geophysical Data with Geologic Constraints to Infer Tectonomagmatic Controls on Mineral Systems in the Yukon-Tanana Uplands, Alaska, and Keweenaw Peninsula, Michigan

Abstract: Critical minerals are necessary for the everyday needs of modern human society and are paramount for the advancement of technology. Lithium, cobalt, nickel, and graphite are some examples of critical minerals used in cell phones, military equipment, vehicles, batteries, and other essential products. To increase domestic production of critical minerals, the U.S. Geological Survey (USGS) seeks to identify areas favorable to host deposits of such minerals through the Earth Mapping Resources Initiative. In collaboration with the USGS, the proposed research aims to identify tectonomagmatic controls of mineral systems in the Yukon-Tanana Uplands (YTU), Alaska, and along the Keweenaw Peninsula (KP), Michigan, using geophysical and geologic data to better understand the distribution and origin of such systems and to judge critical mineral potential in the two areas.

Both the YTU and KP have the potential to host critical mineral deposits, however, mineral systems in these areas are not completely understood. Critical minerals in the YTU are most likely to occur as secondary minerals associated with precious metal mineral systems. Aeromagnetic data will be interpreted, modeled, and integrated with regional geology, magnetic susceptibility measurements, and geochemical data to aid in delineating the boundary between the parautochthonous North American Basement (NAb) and allochthonous Yukon-Tanana Terrane (YTT) that underlie the YTU. Establishing a firm boundary for these terranes has major implications for understanding the origin and distribution of mineral systems across the YTU (e.g., porphyry Cu-Au, orogenic Au) and, consequently, the potential for such systems to host critical minerals. The research will emphasize developing geophysically mappable criteria for these and other mineral systems and the plutonic suites that may be associated with their deposition and enrichment. Along the KP copper district and its southwest extension, gravity and magnetic data, and possibly seismic reflection data, will be acquired to model the structure of the Midcontinent Rift System (MRS), thereby testing published cross-sectional models for the rift and the Keweenaw fault system (KFS). Better definition of the KFS is relevant to understanding migration pathways of copper-bearing hydrothermal fluids that produced economic deposits of copper and silver in the region. Quantitative geophysical modeling in the region can be tightly constrained by bedrock outcrops and rock property measurements (e.g., density, magnetic susceptibility). A better constrained subsurface model across the southeast margin of the MRS will establish a stronger tie to offshore geophysical data previously collected across Lake Superior. Such models should also improve the definition of known faults in the KFS as well as identify new faults beneath Jacobsville Sandstone, thus helping to infer mineralization pathways for copper and other elements associated with the MRS.

Braxton Murphy Receives Research Fund from the Institute on Lake Superior Geology

Published

Braxton Murphy stands by a mineral wall.

Each year the Institute on Lake Superior Geology (ILSG) offers competitive funding for student research projects that focus on the geology of the Lake Superior region. This year, Braxton Murphy, a senior in geological engineering, was awarded $500 to support his project titled “Determine the Relative Paleostress State and Tectonic Conditions That Resulted in Formation and Movement of Faults of the Keweenaw Fault System near Houghton, Michigan.”

Braxton’s research with Jim DeGraff involves measuring slip indicators along the Hancock fault where it is exposed in the Quincy Mine workings and at a rock quarry near the town of South Range. These data will be analyzed to infer the paleostress state that caused faults in the Keweenaw fault system to move, thus allowing different ideas about the Midcontinent Rift System to be evaluated. Research activities in fall 2023 focused on the Hancock fault, and next year will focus on the South Range quarry.

Research findings will be presented at the 70th annual ILSG meeting to be held at Michigan Tech in May 2024.

Dear GMES Alumni and Friends,

When I became the department chair, I stopped using ‘Professor of Geophysics’ in my title and email signature. Instead, I now simply refer to myself as ‘Professor and Chair.’ This change reflects the fact that the success of all our programs and the department as a whole is equally important to me. I aspire to see our four major programs complement each other, combining our traditional strengths while equipping our students with the skills and tools needed for success in meeting the challenges of the 21st century.

Aleksey Smirnov, Professor and Chair

Student enrollment remains the first priority for the Department. Currently, our undergraduate cohort is a healthy size, consisting of 73 students split between our four majors: Geology (28), Geological Engineering (23), Mining Engineering (16), and Applied Geophysics (6). Our nearly equal gender parity has consistently been one of the best within Michigan Tech. We currently have 34 MS students and 12 PhD students, with 12 more MS students joining us this spring semester 2024.

Even so, we have the capacity to accommodate still more GMES students and we work hard to bring them to Michigan Tech. Scholarships remain one of the most efficient tools to attract new students.  

We also recently started development of a new articulation agreement with Minnesota North College, just as we did with Northwestern Michigan College last year. These agreements allow community college students to transfer their two-year credits to Michigan Tech and receive their Bachelor’s degree in two years.

Our capable, dedicated, enthusiastic students continue to be very successful in their classes and professional development. Our award-winning student chapter of the American Institute of Professional Geologists attended the AIPG National Conference in Kentucky in September. Student success stories—such as  John Myyard’s and Brendan Harville’s—are always inspiring and rewarding for all us who strive to help students.  

Our alumni community is invaluable to our department’s success. We’ve been delighted to reconnect with many of you at various events, including the GMES social event at the Annual SME Conference and Expo in Denver, and the Michigan Colleges/Universities Joint Alumni Reception at the GSA Annual Meeting in Pittsburgh. We look forward to reconnecting with you at future events, including the upcoming Alumni Reception at the SME MineXchange Conference in Phoenix on Tuesday, February 27, 2024, from 5:30 to 7:30 PM.

In October, it was a pleasure to welcome alumna Mary Herrmann-Foley, who returned to campus as a distinguished guest seminar speaker, sharing insights on the pivotal role of geological engineering in the energy transition. 

With your support, we can enhance our educational offerings, expand scholarship opportunities to benefit more students, and bolster their competitiveness in the job market. Your contributions also provide valuable support for student travel and professional development. For more details on how to make a difference, visit mtu.edu/geo/department/giving, or please feel free to contact me at asmirnov@mtu.edu.

Lastly, we are always glad to hear from you! Please share your thoughts on what and how we can do better, and update us on your own endeavors and achievements.

Title: An Investigation of Microseismicity During the 2018 Kīlauea Caldera Collapse

Abstract: The 2018 Kīlauea volcano eruption and incremental caldera collapse was accompanied by more than 60,000 seismic events cataloged by the Hawaiian Volcano Observatory as well as 62 caldera collapse events. The majority of seismicity occurred on the eastern side of the caldera between daily collapses. However, the majority of caldera subsidence occurred to the west. To understand the collapse mechanics behind this variance in subsidence and seismicity across the caldera region, repetitive waveforms and source properties can be studied.

Repeating seismic events suggests a common source that is not moving or destroyed. At Kīlauea, clusters of repeating events can indicate source processes throughout collapse cycles. REDPy, a repeating earthquake detector tool for Python, cross-correlates seismic events to determine repetition. Events are separated into families or listed as orphans if no matches are found. We used data from HVO network stations surrounding Kīlauea’s summit. Possible events were identified using an STA/LTA trigger algorithm with a long-time average trigger of 8 seconds, a short-time average trigger of 1 second, and a trigger on/off range of 1-2.5. A minimum correlation coefficient of 0.7 was used to group over 167,000 recognized events from April 29th to August 2nd into nearly 6,000 families. Of these families, 697 were chosen as ‘clusters of interest’ for including >100 events or persisting for 7 days or more. P wave first motions were manually picked for waveforms associated with clusters of interest. These clusters were then located using P wave arrival times, and focal mechanisms were modeled for viable events to learn more about their source processes and relationship to collapse mechanics.

Dilatational first motions dominate our catalog and indicate crack-closing sources with possible relationships to conduit collapse after magma withdrawal and crack closure due to fault motion. Focal mechanism models produced mismatched station polarities indicative of non-double-couple sources, further aiding the hypothesis that dominant events involve a negative volumetric component. Focal spheres show evidence of ring faulting that is likely responsible for these non-double-couple events through the motion of concave fault structures presenting as repetitive crack closure along caldera margins.

Brendan Harville Presents at the Michigan Space Grant Consortium Annual Conference in Kalamazoo, MI

Published
By

From his first weeks in the GMES Department, Brendan Harville was interested in getting involved in research. Through a handful of well-timed events in Brendan’s first semester, he seized an opportunity to submit a research proposal with Dr. Greg Waite to the Michigan Space Grant Consortium (MSGC) undergraduate fellowship to conduct research regarding “Seismic Amplitude-based Lahar Tracking for Hazard Risk Mitigation at Fuego Volcano in Guatemala.” Brendan’s proposal was selected, leading him to plan fieldwork in Guatemala with fellow PhD student Gustavo Béjar-López. Brendan and Dr. Waite used seismic data to create a model that
can locate and track how lahars propagate down drainages from Fuego’s flanks. The work took many twists and turns (as research often does!) and resulted in an improved understanding of how the morphology of Fuego and its many drainages influence lahars and their impacts. Brendan’s work was accepted by MSGC for an oral presentation at the MSGC Annual Conference on October 21, 2023. GMES student Conor Large accompanied Brendan for his presentation over MTU’s Fall Break.

Reflecting on the entire MSGC experience, Brendan says, “My experience with undergraduate research through MSGC was invaluable. I met, connected, and collaborated with many admirable and inspiring peers and mentors for which I am truly grateful for. Special experiences like these are what invigorate and propel students like me toward future goals and aspirations. I would never have enjoyed this opportunity if I hadn’t pushed through my initial fears and feelings of self-doubt.”

GMES celebrates Brendan’s accomplishment and is proud to have submitted four new MSGC proposals this week for the Consortium’s annual call.
