About My Research
My students and I focus our research in the broad areas of glacial geology, hydrogeology, air quality, and genesis of ore deposits. Much of my ongoing work focuses on reconstruction of large-scale flow patterns of the Laurentide Ice Sheet using dispersal of erratics and landform suites, particularly drumlins, eskers, and transverse ribbed moraine (Rogen moraine). Hydrogeology has always been of particular interest to me, particularly groundwater recharge at the regional scale. More recently, my research has focused on the reconstruction of air quality in central England during the Industrial Revolution. Weathering of lead-lettered marble gravestone provides an excellent record acid deposition. By measuring surface recession of marble gravestones in cemeteries across the Midlands of England, we can reconstruct the spatial and temporal history of acid deposition and air quality.
Another interest of mine in the genesis of ore deposits, and with the help of my colleagues Phil Larson (Hibbing Taconite Company) and George Hudak (Natural Resources Research Institute (NRRI), University of Minnesota Duluth) we have explored the genesis of Neoarchean, Algoma-type iron formation in the Vermilion District. Our work in the Vermilion District of northern Minnesota also involves the genesis of peperite, rock formed essentially in situ by disintegration of magma intruding and mingling with unconsolidated or poorly consolidated, typically wet sediments.
