Svanbergite

Lars Fredrik Svanberg, a Swedish chemist and Professor of Mineralogy at the University of Uppsala in Uppsala, Sweden, is honored as the namesake of this mineral. Svanbergite can be found in aluminum-rich, mid-grade, metamorphic deposits, in bauxite depositsm and replacing apatite in hydrothermal vein and disseminated ore deposits as a product of sulphatic alteration. There are quite a few repoted localities for Svanbergite. Svanbergite is insoluble in acids.
