Svabite is also the arsenate analogue of Fluorapatite. When the mineral Fluorapatite occurs near arsenic-bearing ores, some of the phosphate ions are often replaced by arsenate ions. When the arsenate ions outnumber the phosphate ions the mineral becomes Svabite. It was named in 1891 by Hjalmar Sjögren after Anton von Swab. Svabite can be found in both Sweden and Germany.
