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.
