Description:

Abstract: In order to support science-based water resource management, a systematic effort was undertaken to characterize the nature and function of the hydrogeology in Jo Daviess County, Illinois. Jo Daviess County is a karst area. Karst is a geologically and hydrologically integrated or interconnected and self-organizing network of landforms and subsurface large-scale, secondary porosity created by a combination of fractured carbonate bedrock, the movement of water into and through the rock body as part of the hydrologic cycle, and physical and chemical weathering (Panno, S.V. et al, 2017). Springs, cover-collapse sinkholes, crevices, and caves are among the defining features of a karst terrain; each of these features is found in Jo Daviess County. Examples of these features have been located in the field and characterized by scientists from the Illinois State Geological and Water Surveys (Prairie Research Institute, University of Illinois at Urbana-Champaign). The lead-zinc ore deposits of the Driftless Area, which includes Jo Daviess County, were emplaced within the Galena Dolomite 270 million years ago (Brannon et al. 1992). Ore-forming and associated solutions (hot brines) migrated through carbonate rocks along existing fractures and were responsible for enlarging many of these fractures into crevices. The crevices and infilling sulfide ore deposits created by these solutions have the same distribution and orientation as those identified as crop lines by Panno, Luman and Kolata (2015) using remote sensing techniques. Consequently, maps of mines and mining activities reflect the fracture and crevice orientations and provide additional information about the physical characteristics of the bedrock and aquifers of the Driftless Area. This dataset was developed from the original IMDA documents by the Illinois State Geological Survey (ISGS) in fulfillment a grant from the United States Geological Survey (USGS) National Geological and Geophysical Data Preservation Program (NGGDPP). The IMDA is a detailed set of paper records for the Lead-Zinc District in Jo Daviess County in northwestern Illinois for the period 1949-1970. The IMDA consists of large-scale (1"=200') 36"x30" sheet section maps depicting mining digs and borehole locations, and a set of 8-1/2"x11" datasheets containing borehole logs and mineral analyses (assays and/or visual estimates at various depths).The following document is directly related to this dataset:Klass, R. and Z.

Purpose: This dataset contains GIS polygons depicting surveyed outlines of named mine diggings digitized from the U.S. Bureau of Mines (USBM) Illinois Mineral Development Atlas (IMDA) for Jo Daviess County, Illinois. This is one of several datasets compiled for the Karst Feature Database of Jo Daviess County, IL and hosted by the U.S. Fish & Wildlife Service. Thumbnail photo credit: Mansberger et al. 1997

Data Quality Information:

Logical Consistency Report: The IMDA grant project scanned IMDA mining borehole datasheets and corresponding location maps for the Lead-Zinc mining district of Jo Daviess County IL. The scanned TIFF maps were georeferenced to GeoTIFF files using ArcGIS and used to precisely create digitized outlines of Named Mines and Unnamed Mines areas as marked on the scanned and georeferenced maps. The completed ArcGIS file geodatabase dataset contains the digitized outlines of 15 known (Named) mines and the digitized outlines of 310 unknown (Unnamed) mines, all of which were precisely located and digitized from 246 scanned and georeferenced section maps. To facilitate feature digitization, the 246 georeferenced map images were programmatically trimmed at the section lines and combined into a single mosaicked image using automated methods. This eliminated the need to handle 246 separate map layers in ArcGIS, as well as the need to frequently re-order or turn on and off map layers in GIS due to adjoining map border overlap.

Process Description: This dataset was developed from the original IMDA documents by the Illinois State Geological Survey (ISGS) in fulfillment of a grant from the United States Geological Survey (USGS) National Geological and Geophysical Data Preservation Program (NGGDPP). The grant project scanned IMDA mining borehole datasheets and corresponding location maps for the Lead-Zinc mining district. The maps were georeferenced and used to precisely locate each borehole (separate and co-related dataset) as well as create GIS outlines of mined areas as marked on the maps (this dataset and co-related Unknown Mines dataset). The project results included GIS location and basic data for 4871 boreholes each linked to the corresponding datasheet/log, outlines of 15 known (named) mines, and outlines of 310 unknown mines/diggings, all precisely located from 246 section maps. To facilitate borehole and other feature digitization, the 246 georeferenced map images were programmatically trimmed at the section lines and combined into a single mosaicked image using automated methods. This eliminated the need to handle 246 separate map layers in GIS, as well as the need to frequently re-order or turn on and off map layers in GIS due to adjoining map border overlap. The project also compared and reconciled current ISGS digital records with the IMDA records, filling in gaps in ISGS digital data. Reconciliation also discovered errors in both sets of data which were corrected.
