This programme is based on the Handbook for Soil Thin Section Description by P. Bullock, N. Fedoroff, A. Jongerius, G. Stoops and T. Tursina. 1985, published by Waine Research. Wolverhampton (UK).

The keys that Stoops has developed to make it easier to interpret the terms defined in the "Handbook" will also be used (Key to the ISSS "Handbook for Soil Thin Section Description" Stoops, G. Laboratorium voor Mineralogie, Petrologie en Micropedologie, Geologisch Instituut, Universiteit Gent, Krijgslaan 281, S8, B-9000 Gent, Belgium).
