Thin sections prepared primarily in the course of research conducted by geologists of the Wisconsin Geological Survey. There appears to be a set of USGS-related thin sections, as well, but these are not evaluated at this time. Thin sections are tied to field notebooks, which are being reviewed as time allows. Certain physical collections have been located, but their geographic location is uncertain until the field notebooks can be tied to the actual thin section. We must tie physical materials to field notebooks in order to develop geographic coordinates for specific thin sections. Work to date has identified locations of physical items and is currently focused on assessing the notebooks themselves. There are 1,700...

Cores represent over 2,000 individual core sites drilled across the State of Wisconsin; stored in over 56,000 (mainly cardboard) boxes; representing approximately 650,000 linear feet of the subsurface. The Flambeau Core subcollection is approximately 3 percent of the collection of rock cores from Wisconsin. Documentation for the Wisconsin core collection is routinely updated, as information becomes available.
Index of unpublished, archival resources, that may aid researchers in locating critical mineral deposits in Wisconsin. The approximately 2500 items in this collection are from eight major and two smaller collections. The item title contains the focus area to which the item pertains. The resources listed are stored at the WGNHS office in Madison, Wisconsin, and though much of this collection is still on paper only, any items will be made available to researchers upon request.
The Lynne Deposit is a Volcanogenic Massive Sulfide Deposit in Oneida County in northern Wisconsin containing zinc, lead, silver, and small amounts of gold and copper. In 1990 and 1991, the Noranda Company drilled 133 exploration boreholes, and the core from some of these holes was donated to WGNHS and the Natural Resource Research Institute (NRRI) in Duluth, MN. In 2021, the NRRI donated core from seven holes to WGNHS. These cores were photographed, and detailed logs were created by Dr. Robert Lodge and students from the University of Wisconsin Eau Claire. Original documentation from the Noranda Company including logs, assays, cross sections, reports, and a site map are available at Oneida County’s website: https://www.co.oneida.wi.us/archive/mining/category1da1.html?linkcatid=9...
Approximately 23,000 data points showing depth to bedrock in Wisconsin in an ArcGIS Online map. Data points are based on water well drilling records.
This collection is comprised of approximately 1,945 boxes of well cuttings from holes drilled in Grant, Iowa, and Lafayette Counties, Wisconsin by the New Jersey Zinc Company. Locations are assigned to the center of the PLSS Quarter- Quarter section from geologic logs for each set of samples.

Sediment samples are splits from samples processed for textural analysis, geochemistry, color, and magnetic susceptibility. These are a variety of sediment samples, including mostly subsurface samples, collected in the course of Quaternary geology investigations at the UW-Madison Department of Geology and Geophysics and at the Wisconsin Geological Survey. These samples were transferred to the WGNHS in the winter of 2009-2010. They constitute the TillPro sub-collection of sediment samples in Geobase, our sample tracking system. There are more than 5,000 samples in this collection.
Collection of 20 geologic maps which are now available in geodatabase (.gdb) format following the USGS Geologic Mapping Schema (GeMS). Current collection consists of 16 county maps, Quaternary, Pleistocene, and bedrock, 1:100,000 scale, 3 regional maps, 1:250,000 scale, and one bedrock map at 1:100,000 with multiple counties. Geodatases are available as downloads from the WGNHS web site.
WGNHS has approximately 240 cores donated to us by the Wisconsin Department of Transportation. The cores are from shallow holes drilled in the course of construction projects, mostly for bridges, culverts, and retaining walls. Photographs of the core are available through the WGNHS Data Viewer, and logs for approximately 70 of the cores are available on request.
Collection of cores from 2069 holes in critical mineral focus areas in Wisconsin. This is a subset of the collection, Rock cores from Wisconsin, cores drilled from sites across the state. Metadata follows the UGSS borehole template, with an added field for focus area. Each point shows a drillhole in one of approximately 20 critical minerals focus areas in Wisconsin. Core has been indexed by location and may not show evidence of critical minerals. Three focus areas are quite large and are represented by a large number of drillholes: Pembine-Wasusau terrane VMS, Archaean gneiss terranes, and Midcontinent Rift conduit-type magmatic sulfide Ni-Cu-PGE, but the usefulness of this core in identifying critical minerals...
Roland D. Irving established the Lake Superior Division of the USGS in 1882. As head of the Division, Irving began a detailed survey of the Upper Midwest during which he pioneered the application of microscopic petrography. The Division laid the groundwork for all later investigations of the Lake Superior region Precambrian rocks (Dott, 2001). The raw data used to produce this influential work is detailed in the Lake Superior Legacy Collection field notebooks and ledgers. Scanned copies of the notebooks can be accessed through: http://data.wgnhs.wisc.edu/lake-superior-legacy/index.html.

Approximately 18,000 data points showing depth to Precambrian in Wisconsin in an ArcGIS Online map. Data points are based on well records, drillhole core, and geologists' interpretations of samples and drill records. Data points are sparse in areas where Paleozoic bedrock overlies the Precambrian.
Quaternary Core collected from more than 600 sites drilled in unconsolidated geologic materials across the State of Wisconsin since 2011. This collection represents more than 36,000 linear feet of the subsurface. In addition to locations of core, the collection includes data on type, date and depth of boring as well as sediment characteristics such as grain-size, if the sample was subsampled for further testing, as well as more than 1,300 photos taken at 5-ft depth intervals of core. Locations and available metadata can be viewed at https://data.wgnhs.wisc.edu/data-pres-2018/. New locations are added to this online map as they are added to the WGNHS sample tracking system, Geobase.

Hand specimens of rocks collected as a part of field work conducted primarily by present and former WGNHS staff members. Samples date from the early 20th century to the 1990s and were collected throughout the state. Many of the samples are described in the historical field notebook collection, and relationships between the samples and the field notebooks have been established and captured in identifiers. Locations for samples were taken from field notes, maps, and accession lists. There are approximately 5,700 hand samples in this collection.

Rock cores from Wi - Flambeau Mine. The Flambeau Core is a sub-collection of WGNHS’s collection of rock core. It consists of 1490 boxes taken from 50 holes drilled in Anomaly 22 of the Flambeau Mine site near Ladysmith in Rusk County, Wisconsin. These core samples have been thoroughly inventoried, logged, photographed, and evaluated for pyrite degradation. Logs, photographs and other metadata are available to researchers upon request. The subject of an FY2015 data preservation project, this core is represented by much more extensive metadata than is the rest of the core in our repository. This data preservation work also resulted in re-evaluation of the geochemistry and petrography of the ore body in Anomaly...
The collection contains location maps, logs, cross sections, geochemical sampling results, geologic maps, and reports. These records are primary source information for 289 rock cores in our collection. These documents complement the rock cores that Lehmann and Associates had earlier donated to the Wisconsin Geological Survey. These documents can be viewed on an online interactive map application at https://wgnhs.wisc.edu/mineral-exploration-in-northern-wisconsin-web-app/ or http://arcg.is/1PaySr.

Photographs of core from 56 boreholes in Earth MRI focus areas in Wisconsin hosted on the WGNHS data viewer. Focus areas represented are: Midcontinent Rift mafic-ultramafic satellite intrusions, Paleoproterozoic weathering beneath mature quartzites, Upper Mississippi Valley Mineral District, Wolf River Batholith, and Upper Ordovician Phosphates.Focus areas are south of ceded territories except for the Midcontinent Rift mafic-ultramafic satellite intrusions, also know as the Round Lake exploration, as this is the only known site of exploration for a critical mineral, vanadium, in Wisconsin. Borehole data for these 56 drillholes has also been created. The core represented in the photographs is a subset of the collection,...
The Mineral Development Atlas (MDA) was a joint project by the United State Geological Survey (USGS), the United States Bureau of Mines (USBM), and the state surveys of Wisconsin, Illinois, and Iowa, and was launched in 1945 to gather information about mining and exploration in the lead-zinc district. The Atlas consists of section maps at 1:2400 scale showing exploration and mining activity in the lead-zinc district of the Upper Mississippi Valley. When the USGS offices in Platteville, WI closed, the Atlas was distributed to the states. The Wisconsin portion covers primarily Grant, Iowa, and Lafayette Counties, and WGNHS is currently working towards making the Wisconsin portion of the Atlas publicly available online....
