Sieve Analysis Physical Samples

The Indiana Geological Survey (IGS) has a collection of approximately 40,000 processed grain-size sediment samples. These samples are kept in individual packets labeled with an identifier and are stored in about 700 core boxes. This collection of physical sediment samples was derived from sieve analysis tests performed on drill-cutting samples collected between 1967 and 1997. The collection is broken down into original samples as well as grain sizes including less than 2mm, sand, granules, and pebbles.
