Exciting microscope images of clays (Kaolinite and Bentonite pure clay minerals, and the fine portion of a natural soil).

The collection was released on December 2015 by Associate Professor Joseph Dove from Virginia Tech and his research team for educational use, as a result of an ongoing research on the silicification of fine-grained soils, supported by the Geomechanics and Geomaterials program of the National Science Foundation.

Images were acquired at several "regions" on each sample. Within each region, images were collected at progressively higher magnifications.
