Collection of Thin sections and polished sections for Indiana

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.
