The 10th International Basement Tectonics Conference was conducted on
the campus of the University of Minnesota, Duluth, in Duluth, Minnesota,
USA, from August I through August 11, 1992. A total of 78 individuals
were in attendance, 47 of which represented the host country, with the
remaining 31 traveling from 11 different foreign countries. The four
days of presentations were divided into three technical sessions, namely
"Shear Zones", "Basement Control On Younger Structures", and "Rifting-
Midcontinent Rift System". This tripartite conference theme was also
employed in the field trip agenda with three excursions being offered,
all ably organized by Field Trip Chairman John C. Green. The
pre-conference trip set the stage through a two day review of the
"Archean and Early Proterozoic Rocks of Northeastern Minnesota". Under
beautiful summer skies, 16 sites were visited within the Vermilion
district of Minnesota, considered to be the best example of an Archean
greenstone belt in the United States. All registrants participated in
the mid-conference trip conducted along the gabbroic and volcanic
terrain of the "Midcontinent Rift, Northeastern Minnesota".
