    Bedrock Geologic Map of a Portion of the South Kawishawi Intrusion, Lake County, Minnesota
    (2014-08) Branham, Jesse; Dove, Andrea; Ferry, Carlos; Gorlick, Jacob; Hoeft, Erin; Pysher, Aaron; Mulcahy, Connor; Peterson, Dean M
    This map is the result of a six day mapping project in the South Kawishiwi Intrusion, which took place from August 3rd through the 8th of 2014. This map was created on a 1:5000 scale by Precambrian Research Center field camp students at the University of Minnesota Duluth under the supervision of Dr. Dean Peterson. Data for this project was compiled from Peterson (2014) and Phinney (1966) and combined with the data that was collected over the mapping period. The purpose of this project was to create a more detailed and accurate geological map of this locality on the Duluth Complex, as well as a better understanding of possible glacial till deposits in the area. This project was also performed to test the conceptual model of this location, which inferred that the lineaments seen on LIDAR of the area consisted of mainly fault-like features and that the area was primarily covered by glacial water table through these fractures/faults due to mining operations and tailings processes. This capstone area was selected under the idea that the proposed conceptual model for the lineaments in the mapping area were incorrect. After six days of mapping and data collection on this location it is accurate to conclude that this area consists of almost entirely bedrock composed of large amounts of varying types of troctolite and anorthosite, with a sparse amount of localized till piles that consist of small pebbles to large boulders. The 1227 outcrops that were mapped in this area were not found to be fractured/faulted but instead broke apart due to frost wedging. This is the dominant type of mechanical weathering in the area. of this area was found to be false and the local water table and aquifers in this area would not be in jeapordy by consequence of mining operations.

    Bedrock Geologic Map of the Central Part of Knife Lake, Boundary Waters Canoe Area Wilderness, Northern Minnesota
    (2014-08) Krogmeier, Ben; McKevitt, Dylan; Roepke, Liz; Sara, Michael; Szkilnyk, Paul; Jirsa, Mark J
    This map of the central Knife Lake area in the Boundary Waters Canoe Area Wilderness (BWCAW, Fig. 1) is the result of six days of bedrock mapping in August, 2014 by PRC Field Camp students under the guidance of Mark Jirsa, Minnesota Geological Survey, along with information gathered from Jirsa and Miller (2004), Gruner (1941), and Mulcahy and others (2013). The geology in this area has not been mapped in detail due to its remote location. The authors conducted extensive canoe shoreline mapping and inland traverses in an attempt to better define geologic contacts, structural features, and depositional facies for an improved understanding of the region. The relationships between mafic metavolcanic rocks, diverse metasedimentary units, and various intrusions were better characterized. Mineralized shear zones and locally intense sulfide mineralization may be indicators of economic significance within this complex Neoarchean terrane. Field mapping was conducted using 1:24,000 scale maps, and digitally compiled at 1:12,000 scale.

    Bedrock Geologic Map of the Central Wilder Lake Intrusion, Lake County, Minnesota
    (2013-08) Smith, John; Leu, Adam
    This study was done in an attempt more accurately define lithologic boundaries in the central area of the wilder lake intrusion. Data from a 2012 PRC capstone project, Adam Leu’s masters thesis, and previous mapping projects were used to map the western and eastern margins of the intrusion, leaving the middle section mostly inferred. The upper map shows the entirety of the wilder lake intrusion at a 1 to 24,000 scale and the lower map shows the area of interest at a 1 to10,000 scale. John Smith and Adam Leu spent five days camping on the edge of South WIlder Lake, traversing through areas with little to no lithologic data. Since the pagami creek burn had cleared out most of the the vegetation, the primary obsticals were dead fall and marshes. 160 outrops were mapped, but since the main goal was to better define lithologic boundaries, many outcrops that didn’t relate to a change in rock type were not put on the map.

    Bedrock Geologic Map of the Disappointment and Ima Lakes Area, Lake County, Northeastern Minnesota
    (2008-08) Stifter, Eric; Wartman, Jakob; Gibbons, Jack; Kane, Kevin; Murphy, Laura; Carlson, Anders; Mason, Tracey; Hudak, George J; Peterson, Dean M
    This map is the result of seven days of field mapping by the authors in 2008, as well as a compilation of information gathered from Van Hise (1901), Gruner (1941), and Chandler (1991). This map was created by PRC Field Camp students under the supervision and guidance of Dr. Dean Peterson, NRRI Senior Research Associate, and Dr. George Hudak, professor at UW-Oshkosh. The purpose of this map is to aid in understanding the nature of the basal contact between the Duluth Complex and Wawa Subprovince Archean metavolcanic-metasedimentary rocks, which was last mapped in the early 1940's. Additionally, this map will serve as a basis for additional undergraduate honors theses studies. Access to the 663 outcrops mapped for this project was provided by extensive canoe shoreline mapping and traverses in the blown-down bush of the Dissapointment and Ima Lakes field area. This map was made at a 1:10,000 scale, and is the first detailed map done in an area previously mapped on a reconnaissance scale.

    Bedrock Geologic Map of the Disappointment Lake Area, Lake County, Northeastern Minnesota
    (2009-08) Mulvey, Lucy; Ross, Cabin; Zeitler, Joseph; Pendleton, Matthew; McCarthy, Andrew; Copp, Lee; Nowak, Robert; Hudak, George J; Peterson, Dean M
    This map was created by PRC Field Camp students under the guidance of Dr. Dean Peterson, Duluth Metals Limited Senior Vice President of Exploration, and Dr. George Hudak, Associate Professor of Geology at the University of Wisconsin Oshkosh. The purpose of this map is to further understand the relationship between the Duluth Complex and the older Archean metasediment, volcanic and volcaniclastic rocks in the area which were last mapped in the early 1940's by Gruner. This map will also facilitate undergraduate research theses studies. This map is the result of seven days of field mapping by the authors in 2009. Access to the 955 outcrops included in this project was achieved through extensive mapping of shorelines within the Disappointment, Parent and Snowbank Lakes field area combined with multiple traverses through dense bush and swamp areas. This is the first detailed map of the area produced at a 1:10,000 scale.

    Bedrock Geologic Map of the Duluth Complex in the Northern South Kawishiwi Intrusion and Surrounding Area, Lake and St. Louis Counties, Minnesota
    (University of Minnesota Duluth, 2008-05) Peterson, Dean M
    This map is the result of numerous investigations by the author and many others over the last 8 years of the South Kawishiwi intrusion (SKI) and it's contained Cu-Ni-PGE mineralization. Detailed geological mapping evolved from a study of the Nickel Lake Macrodike (NLM) into a comprehensive geologic mapping and compilation project (104,000 acres) to answer some of the fundamental questions on the origin of the extensive known and undiscovered Cu-Ni-PGE mineralization in the northern portion of the SKI. Such an increase in scope is needed due to the economic significance of the published resource estimates (>$146 billion in contained metal) from this area. To date, nearly 15,000 outcrops, 1,400 structural measurements, geology and geochemistry from 773 drill holes totaling over 845,000 feet of core, and 12,500,000 meters of elevated contour lines (see Digital Topography image below) have been integrated into the comprehensive GIS database. The map units of the SKI depicted on this map sheet differ from previous maps from the area, in that the author has consulted with numerous company geologists and defined map units based on what industry geologists use to define rock masses encountered in drill core. This new map includes geology from each of the major lithologic units in the area, namely the Late Archean Giants Range batholith, the Paleoproterozoic Biwabik Iron and Virginia Formations, and the Anorthositic Series, Bald Eagle Intrusion, SKI, and the NLM of the Mesoproterozoic Duluth Complex. There are only a few faults depicted on the map, and literally hundreds of kilometers of linear topographic features that remain to be investigated in detail (see Digital Topography image below). However, little obvious offset of rock units have been observed along these features where investigated in detail, thus the author has purposely not drawn many faults on the map. One main new insight of this recently completed compilation is the recognition that the northeastern extent of the SKI is not a shallowly dipping sill but rather a southwest trending, inclined funnel-like body. Such an interpretation leads to the conclusion that the eastern contact of the SKI, which previously was interpreted as the top of the intrusion, is a basal contact, and thus has great potential for hosting Cu-Ni-PGE mineralization at its base. Understanding the origin of mineralized zones is the goal of all economic geologists, and in magmatic ore systems like the SKI, one must try to imagine the magmatic processes that culminated in the formation of the ores and surrounding rocks, i.e. how did the SKI form? Did the magmas intrude as crystal-laden slurries? Are the "Open" and "Confined" styles of mineralization defined by Peterson (2001) true mappable units? Such thoughts are the basis upon which the author began the quest to complete this map sheet. The author has inserted a number of inset maps and figures for the reader to review and ponder about the possible types of magmatic prosesses that occurred in the area (now depicted on this map sheet) 1.1 billion years ago. It is hoped that careful review of the bedrock geologic map and inset figures will give the reader and user of the map new geologic insight and ideas for future mineral exploration programs and scientific study.
