Charoite is a rare silicate found only at one location in Yakutia, Russia. For its beautiful and uncommon purple color it is used as a semi-precious stone in jewelry. Under the microscope charoite-bearing rocks give an overall feeling of movement, with charoite forming fibrous mats that swirl and fold as a result of deformation during metamorphism. Due to the variable orientation with respect to the polarized light the charoite may exhibit different interference colors. It may be difficult to conceive, but these microstructures tell us that solid rocks can flow. Polarized light photomicrograph of a thin section of rock. Polarized light, crossed polarizers and red tint (lambda) plate. The rock slice (thin section) is 30-micron-thick. Width of view: 5.3 mm | |
