WebNov 23, 2024 · In most cases, however, the crystallites found in nature are much smaller in size. Most rocks, soils, and sands, consist of small submillimeter particles such as iron-containing rocks. If you’d make a cross-section of a rock fragment in preparation for the optical microscope, you’d see the small crystallographic domains in the rocks. Webcrystallography, branch of science that deals with discerning the arrangement and bonding of atoms in crystalline solids and with the …
