    Geology, geochemistry, and PGE potential of mafic-ultramafic intrusions in Minnesota, excluding the Duluth Complex
    (Minnesota Geological Survey, 2006) Jirsa, M.A.; Miller, James D., Jr.; Severson, M.J.
    This open-file contains data from both the first and the second phase of a 3-year study to evaluate platinum group element potential in mafic-ultramafic intrusions throughout Minnesota, excluding the Duluth Complex. Specifically, it reports the results of geochemical analyses conducted on 20 intrusions selected from more than 150 that were inventoried during the first phase of the study released in 2003. Some overlap may occur between the geochemical data listings from Phase 1 and Phase 2.
