About Jeanbandyite
Formula:
Fe3+xFe2+1-xSn(OH)6-xOx
(1 ≥ x > 0.5)
Ideal end-member: Fe3+Sn(OH)5O; originally assumed to be (Fe3+1-x,◻x)(Sn1-y,◻y)(OH)6
Ideal end-member: Fe3+Sn(OH)5O; originally assumed to be (Fe3+1-x,◻x)(Sn1-y,◻y)(OH)6
Colour:
brownish orange
Hardness:
3½
Specific Gravity:
3.81
Crystal System:
Tetragonal
Member of:
Name:
Honouring Mrs. Jean A. Bandy (1900-1991), of Wickenburg, Arizona, USA, who donated to the Los Angeles Natural History Museum the collection on one of whose specimens this new mineral was discovered. The mineral bandylite was named for her husband.
Dimorph of:
Stottite Group. Jeanbandyite and natanite represent the only hydroxide-bearing minerals with dominant Fe and Sn.
Oxidised counterpart of natanite with partially deprotonated oxygen sites. Double perovskite of BB'(OH)6 type. The deprotonated domains have local short-range order.
A dark violet and hard mineral of the (Fe,Mn)(Sn,Ge)(OH)6 composition is reported as "Mineral D" and the Sn-analogue of stottite, from Tsumeb, Namibia (Geier & Ottemann, 1970).
