Nontronite is a fascinating clay mineral belonging to the smectite group, which also includes well-known minerals such as montmorillonite and saponite. Named after the picturesque town of Nontron in France, where it was first discovered, nontronite is commonly found in low-grade metamorphic rocks, hydrothermal deposits, and weathered volcanic ash layers. This mineral is prized for its beautiful green coloration, which ranges from soft pale green to deep rich green depending on its iron content, making it a favorite among mineral collectors and enthusiasts.
