Nontronite is a green clay mineral belonging to the smectite group, which also includes minerals like montmorillonite and saponite. Named after the town of Nontron in France, where it was first discovered, nontronite is typically found in low-grade metamorphic rocks, hydrothermal deposits, and weathered volcanic ash layers. Its green coloration ranges from pale to dark green, depending on its iron content, making it a prized mineral for collectors, geologists, and mineral enthusiasts.
