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.
