Meeting Summary

The 47th Annual Institute on Lake Superior Geology Annual Meeting was held at the Sheraton Madison Hotel, the same location as the 1973 meeting. The 2001 meeting focused on hydrogeologic aspects of arsenic in groundwater, completion of acquisition of detailed regional geophysical data; the evolution of the post-Penokean--pre-Keweenawan crystal terrane of North American in 36 poster displays and 32 oral presentations . The two days of technical sessions were preceded by Field Trip 1 - Sedimentologic, Tectonic and Metamorphic History of the Baraboo Interval led by L. Gordon Medaris, Jr. , and Robert H. Dott, Jr. (University of Wisconsin-Madison) , and followed by Field Trip 2 - Upper Mississippi Valley Zinc-Lead District led by M.G. Mudrey, Jr. (Wisconsin Geological and Natural History Survey) and Thomas C. Hunt (University of Wisconsin-Platteville) and Field Trip 3- Industrial Mineral and Aggregate Resources of the Baraboo Interval Quartzites lead by Bruce A. Brown (Wisconsin Geological and Natural History Survey), Frank R. Luther (University of Wisconsin -Whitewater), James W. Schmitt (D.L. Gasser Construction), Susan M. Courter (Michels Materials) and Jennifer Lien (The Kraemer Company)

The meeting began with regional geologic summaries of the Pleistocene of Southern Wisconsin by D.M. Mickelson (University of Wisconsin-Madison) and Lee Clayton (Wisconsin Geological and Natural History Survey), Sequence Stratigraphic Analysis of the Paleozoic by Charles E. Byers (University of Wisconsin-Madison), and Stratigraphic Metamorphic Analysis of the Baraboo Supracrustal Rocks of the Midcontinent by L. Gordon Medaris, Jr. , (University of Wisconsin-Madison). A series of invited presentations completed the morning of the first technical sessions three presentations on Aeromagnetic Investigations in the Midwest.

An invited presentation on an Overview of Arsenic Occurrences and Processes Controlling Arsenic Moblity in Ground Water by D. Kirk Nordstrom (U.S. Geological Survey) kicked off a special session of four papers on the Hydrogeologic Setting of Elevated Arsenic and Heavy Metals in Public and Private Water Supplies. General geologic topics completed the first day.

Three papers on the Midcontinent Rift started Friday morning, followed an invited symposium of eight papers on the Thermo-Thermo-Tectonic History of 1800 to 1200 Ma post-Penokean to pre-Keweenawan. The remaining significant presentations dealt with Archean and platinum-group element geology. The technical program was completed by 3:30 p.m.

Proceeding including Pat 1 (Programs and Abstracts) and Part 2 (Field Trip Guidebook) are available from the Institute .

After the break, Mike Mudrey and Bruce Brown regaled the remaining participants with previews of their field trips (Field Trip 3 was eventful in that a flat tire delayed the trip ( How many ILSGers does it take to change a tire? Three! Frank Luther, Mark Jirsa and Bob Reszka), and Brad Singer and John Valley lead the group on an impressive tour of the isotope laboratories in the Department of Geology and Geophysics. The entire group of ILSG participants remaining in Madison joined the Department of Geology and Geophysics Geology Club for the annual Departmental Picnic courtesy of contributions from Steve Kircher, Crandon Mine Development, Nicolet Minerals, and William J. Cronk, Layne Northwest, directly to the Institute.


Annual Banquet and Goldich Award

At the Annual Banquet Bruce R. Doe prepared, and Michael G. Mudrey, Jr. delievered a biographic history of Samuel S. Goldich who passed away on 20 December 2000 in Applewood, Colorado. After the introduction of 6 of the surviving Goldich recipients, an upbeat Gene LaBerge presented John S. Klasner with the Goldich Medal for 2001 for his contributions to the Institute and Lake Superior Geology. Tom Hunt illustrated the successful reclamation of the Ladysmith Mine of Kennecott Mining for the after dinner address, and Peter Hinz of the Ontario Geological Survey invited participants to the 48 th Annual Meeting in Kenora .
