|Name:||Ottoliniite was named for Luisa Ottolini (Pavia, Italy) to acknowledge her contribution to crystal-chemical studies of minerals, and particularly of amphiboles.|
Ferri-ottoliniite was approved as a new mineral in 2001. In the 2012 amphibole nomenclature, it's compposition is considered intermediate between clino-ferri-holmquistite and magnesio-riebeckite, and the ottoliniite root name is discredited.
The holotype material, A(K0.07Na0.38)B(Na0.70Li1.24Ca0.06)C(Mg1.35Fe2+0.92Mn2+0.13 Zn0.31Fe3+1.71Al0.10Ti0.06Li0.42) Si8 O22 (OH1.51F0.47). has Li>Na in the B position and is consequently considered a clino-ferri-holmquistite.
(TL) indicates type locality. ? indicates mineral may be doubtful at this locality. All other localities listed without reference should be considered as uncertain and unproven until references can be found.
