Ferro-glaucophane from
Chalcis, Euboea, Central Greece, Greece


Locality type:Municipality
Classification
Species:Ferro-glaucophane
Formula:◻Na2(Fe32+Al2)Si8O22(OH)2
Comments:Xypolias et al. (2012) presents a microprobe analysis from blueschist facies amphiboles from the Ochi Nappe. The analysis corresponds to the following formula:

Na0.036(Na1.942Ca0.058)2.00(Mg1.45Mn2+0.04Fe2+1.6Fe3+0.495Al1.415)5.00(Si7.996Al0.004)8.00O22(OH)2


F3+ and O content is calculated, and formula normalized in accordance with Andrew J. Locock (2014): An Excel spreadsheet to classify chemical analyses of amphiboles following the IMA 2012 recommendations. Computers & Geosciences, Volume 62, pp 1-11.
