Arangasite, Al2(PO4)(SO4)F · 7.5H2O, a new mineral from the Alyaskitovy deposit, Eastern Yakutia, Russia

A new hydrous aluminum sulfate-phosphate-fluoride arangasite, Al 2 (PO 4 )(SO 4 )F · 7.5H 2 O, has been found in cassiterite-silicate-sulfide ore at the Alyaskitovy deposit, Indigirka River basin, eastern Sakha (Yakutia) (64°39′ N, 142°70′ E). The new mineral was named after its type locality, Arang...

Description
Summary:A new hydrous aluminum sulfate-phosphate-fluoride arangasite, Al 2 (PO 4 )(SO 4 )F · 7.5H 2 O, has been found in cassiterite-silicate-sulfide ore at the Alyaskitovy deposit, Indigirka River basin, eastern Sakha (Yakutia) (64°39′ N, 142°70′ E). The new mineral was named after its type locality, Arangas Creek. It belongs to the secondary minerals of the oxidation zone and occurs in cavities within quartz-muscovite-tourmaline-sulfide veins and adjacent greisen. Arangasite is associated with other secondary minerals: phosphorscorodite, fluellite, gypsum, colquiriite, strengite, mansfieldite, and sinkankasite. Arangasite forms white compact segregations composed of fine-lamellar aggregates. This paper reports data on its chemical composition, optical, radiographic, thermal, and IR-spectroscopic characteristics.
