Excerpt from Integrated Seismic, Resistivity, and Geologic Studies of Glacial Deposits

A study integrating seismic, resistivity, and geologic meth ods was made of the glacial deposits in three areas in the northern half of Illinois. Employment of all three methods increased the te liability of the identification of materials and determination of thick ness of units by eliminating some of the problems encountered when a single method was used.

Resistivity values are a guide to the identification of, and depth to, low-velocity sand and gravel, and with these layers ao counted for, seismic refraction methods give more reliable bedrock depths Resistivity methods also aid in identifying the sequence and lithologic type of high-velocity drift materials. Depths to the base of high-velocity layers can be determined from resistivity curves, and bedrock depths can then be more accurately calculated from seismic refractions.
