- Abstract
An occurrence of variscite containing strengite, as well as other minerals from both the variscite and metavariscite groups, was discovered in the late 1970s in central Tajikistan. The material, ranging from light blue to light green to green, is suitable for cabochon cutting. The samples presented in this study showed traces of sulfur and arsenic, with higher iron and generally lower vanadium and chromium concentrations than variscites reported from other localities. These differences may result from the intergrowth of variscite with other minerals from the variscite and metavariscite groups.
