Chemistry of dark zinnwaldite from Bom Futuro tin mine, Rondônia, Brazil
Journal: Mineralogical Magazine
Published: 01 August 2000
Mineralogical Magazine (2000) 64 (4): 699–709.
...G. R. Lowell; M. Ahl Abstract Physical and chemical properties of lustrous black mica from greisen veins at the Bom Futuro tin mine indicate that it is a relatively Fe-F-rich, Li-poor zinnwaldite with a composition near the midpoint of the polylithionite-siderophyllite join. On the basis of 22...
