This collection consists of glass microscope slides (1"x3") on which is glued a thin slice of rock ~3cm long, 2cm wide, and 0.003cm thick. At this thickness, most minerals are transparent, so they can be easily seen and studied in great detail. The slides are numbered and filed in special slide boxes located in the basement of the Indiana Geological Survey. The numbers correspond to a listing with pertinent information about the well itself, such as county, location, farm name, number, operator's name, etc. The listing is found next to the slide boxes. Also included is the number of the core from which it came. There are 11 boxes (5.5"x10") of slides with supporting documentation.
The Research and Teaching Core Repository was completed in 1976 and houses drilled cores taken from all over Indiana. It contains approximately 35,000 boxes of core containing 51 miles of rock and sediments. The Core Repository is an asset to the citizens of Indiana and allows both geologists and the public to understand Indiana's geologic past and provide for its future.

State Geologist Charles Deiss (1945-1959) combined the efforts of the Indiana Geological Survey and Indiana University Department of Geology shortly after the start of his tenure, establishing subject-specific research sections within the Survey. This collection contains crushed rock specimens created for use in various analyses, including X-ray fluorescence spectrometry, by members of the Geochemistry Section from 1947-1994. Specimen sources varied but primarily came from bedrock cores in the IGWS core library. Specimens are currently organized by sample ID.
