Note on the mineral list:
"Asbestos" refers to Asbeferrite, a name introduced by Igelström (1867) for a greyish white asbestos amphibole from Brunnsjögruvan, thought to be a variety of Dannemorite (which was renamed Manganogrunerite by IMA in 1997).
Asbeferrite was discredited by CNMMN and defined as a synonym of asbestos (Leake 1978).
Newer studies are needed to establish the exact amphibole species.

'Manganogrunerite' ?
Formula: ◻{Mn2+2}{Fe2+5}(Si8O22)(OH)2
Description: An asbestos-like amphiboles were named as asbeferrite, later thought to be a variety of Dannemorite (which was renamed Manganogrunerite by IMA in 1997). Samples of this materiale is thus sold as " Manganogrunerite". Asbeferrite was however discredited by CNMMN and defined as a synonym of asbestos (Leake 1978). Newer studies are needed to establish the exact amphibole species of this material
