    www.mindat.org/min-6928.html The original material used to describe clino-ferri-holmquistite (IMA1995-045) by Caballero et al (1998) (originally named by them as "ferri-clinoholmquistite") was renamed "sodic-ferri-clinoholmquistite" and finally became Clino-ferro-ferri-holmquistite, its current valid name. The mineral now named clino-ferri-holmquistite was originally published as ferri-ottoliniite (IMA2001-067) in 2001.

    adsabs.harvard.edu/abs/2004PCM....31..375I Abstract This work reports the synthesis of ferri-clinoholmquistite, nominally Li2 (Mg 3 Fe 3+ 2)Si 8 O 22 (OH) 2, at varying f O 2 conditions. Amphibole compositions were characterized by X-ray (powder and single-crystal) diffraction, microchemical (EMPA) and spectroscopic (FTIR, Mössbauer and Raman) techniques.

Amphiboles have been synthesized by hydrothermal techniques at 500-600 degrees C, 1 Kbar P((H2O)) and low oxygen fugacity (close to NNO) at nominal compositions along the join ferri-clinoholmquistite [square Li2Mg3Fe3+ 2Si8O22(OH)21 - ferri-clinoferroholmquistite [square Li2Fe32+Fe23+Si8O22(OH)(2)]- SEM-EDS and X-ray powder diffraction show that at 500 degrees C, amphibole is the ...
