What Is A Thin Section? - When soil scientists and geologists cannot discern characteristics of soil particles and other Earth material with the naked eye, thin sections are prepared.
To prepare thin sections, undisturbed blocks of soil or other Earth material are filled with a glue, called epoxy resin, and are heated. Next, the blocks are allowed to harden
and then placed in a block machine that saws off 1 cm diameter chips. A good specimen chip is selected and polished, then placed on a glass slide. The slide and the chip
are placed in the thin section machine and are trimmed to 50 microns thick on the slide.
