Geological and Geophysical Survey of Fluorspar Areas in Hardin County, Illinois (open access)

Geological and Geophysical Survey of Fluorspar Areas in Hardin County, Illinois

From abstract: Pt 1. The present work seems to confirm the genetic theory previously published, namely that [Illinois Cave in Rock] deposits were formed by ascending solutions. These solutions probably followed minor fissures that connected below with larger fissures, which in turn probably connected with a major fault zone. It is believed that where such minor fissures extended upward only to the shale or other impervious cap rock, or were greatly reduced in size where they penetrated such beds, the solutions spread laterally along the contact and along the limestone beds beneath it and replaced the limestone. Pt 2. This report is a presentation of the results of an electrical-resistivity survey conducted in the fluorspar-bearing areas of Hardin County, Ill., principally during the field seasons of 1934 and 1935.

Hydrologic Effects of Storing Liquified Sewage Sludge on Strip-Mined Land, Fulton County, Illinois

From introduction: In 1971, the U.S. Geological Survey (USGS) began a cooperative study to measure stream discharge, suspended-sediment load, and chemical quality of surface waters draining the project area. In 1976, the study was expanded to include measurement of ground-water levels and quality. The general hydrologic system in the vicinity has been described by Patterson, Fuentes, and Toler (1982).

Plan of Study for the Northern Midwest Regional Aquifer-System Analysis (open access)

Plan of Study for the Northern Midwest Regional Aquifer-System Analysis

From abstract: Sedimentary rocks of Cambrian and Ordovician age form a major aquifer system in most of Wisconsin and Iowa, northern Illinois, northwestern Indiana, southeastern Minnesota, and northern Missouri. Many metropolitan areas depend on the aquifer for all or part of their water supplies. Declines in potentiometric head have been large in the most heavily pumped areas, most notably Chicago, Milwaukee-Waukesha, Minneapolis-St. Paul, and Des Moines.
