    Information Circular 30. Workshop on the Applicability of Gold and Platinum-Group-Element Models in Minnesota
    (Minnesota Geological Survey, 1989) Morey, G.B.
    The geology of Minnesota is highly varied and contains combinations of lithologic and structural factors that are known to be associated with important deposits of metallic minerals elsewhere in the world. Despite this broadly favorable potential for a diverse array of deposit types, however, only the world-class deposits of iron ore have yet been discovered. This suggests that we know too little about the geology, too little about the criteria for recognizing nonferrous mineral deposits, or, as is probably the case, too little about both. As a step toward remedying these deficiencies, a mineral deposit workshop was convened in April 1989 with support from the Minnesota Legislature through the Mineral Diversification Program, as administered by the Minnesota Minerals Coordinating Committee (W.C. Brice, Minnesota Department of Natural Resources, Division of Minerals; P.C. Grew, Minnesota Geological Survey; K.J. Reid, Mineral Resources Research Center; T.B. Johnson, Natural Resources Research Institute). The topic of the workshop was a discussion of mineral deposit models applicable to gold and the platinum group of elements (PGE) in Minnesota. Co-convenors of the workshop were Priscilla C. Grew (Minnesota Geological Survey), Michael P. Foose (U.S. Geological Survey), and Steven A. Hauck (Natural Resources Research Institute, University of Minnesota, Duluth). Professor Samuel S. Adams (Colorado School of Mines) provided special assistance in planning the workshop program. Industry participation was coordinated by Keith Laskowski (Newmont Exploration, Ltd.) and William C. Ulland (American Shield), both of the Minnesota Exploration Association. The body of this report consists of two parts-an overview of Minnesota's geologic framework, by D.L. Southwick, and a summary of the workshop discussions.

    Information Circular 35. Geophysical Solutions to Geologic Problems of Continental Interiors: A Minnesota Workshop
    (Minnesota Geological Survey, 1991) Chandler, V.W.
    Geophysics has long been a companion to geologic studies in Minnesota, where most of the bedrock lies beneath a thick cover of glacial drift. In 1979 the Minnesota Geological Survey (MGS), through funding by the Legislative Commission on Minnesota Resources (LCMR), began an ambitious geophysical project-a state-wide program of high-resolution aeromagnetic surveying. On the occasion of the completion of this highly successful program, the MGS through LCMR support hosted an international geophysics workshop during March 3-6,1991. The main objective of the workshop was to determine how the LCMR data and other geophysical information can most effectively be used, and what sorts of new geophysical investigations are desirable for Minnesota. Such an assessment must address private, academic, and governmental needs and must consider a diversity of topics, including mineral exploration, environmental and ground-water studies, geologic mapping, and crustal studies. The recommended tasks must also be consistent with the MGS mission of geologic mapping and framework studies. Sessions were centered on near-surface studies, geologic mapping, mineral exploration, and crustal studies. Speakers were selected from diverse perspectives and included individuals from the United States, Canada, Australia, and Finland. Posters included presentations by some of the speakers, as well as other geophysicists working in the region. The workshop attracted over 100 earth scientists, representing 10 states and 4 countries, and the sessions stimulated many useful discussions and ideas. This report summarizes the workshop, and discusses some of its most important recommendations. These recommendations will help set the course for Minnesota geophysics into the 21st century.

    OFR13-02, Three-Dimensional Geological Mapping
    (2013) Thorleifson, Harvey; Berg, Dick; Russell, Hazen
    This workshop is designed for those constructing 3D geological maps and numerical models. Our objective is to bring together people dealing with large datasets, and who must integrate variable quality data with high quality data to construct 3D geological models for application such as hydrogeology, engineering, and energy resource assessment. Topics include (1) methods of model construction, (2) managing diverse data of variable quality, (3) ensuring data interoperability, (4) visualization tools, and (5) interaction between mappers, hydrogeologists, energy and mineral resource geologists, engineering geologists, and engineers. The emphasis is on deposits that host potable groundwater, as well as sedimentary basins as a whole.
