ⓘ Albite
Formula: Na(AlSi3O8)
ⓘ Diopside
Formula: CaMgSi2O6
ⓘ Jadeite
Formula: Na(Al,Fe3+)Si2O6
ⓘ Magnesio-arfvedsonite
Formula: {Na}{Na2}{Mg4Fe3+}(Si8O22)(OH)2
Description: A microprobe analysis by Wang et al (2013) corresponds to magnesio-arfvedsonite by using 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 for normalization. The ID depends on the calculated Fe3+/Ftot ratio, and the composition will correspond to eckermannite for low Fe3+. SiO2- 58.98 TiO2 Al2O3- 0.33 FeO- 6.36 MnO MgO- 19.47 CaO- 3.13 Na2O- 9.25 K2O- 0.82
ⓘ Magnesio-riebeckite
Formula: ◻{Na2}{Mg3Fe3+2}(Si8O22)(OH)2
Description: Wang et al (2013) publish 4 microprobe analyses of amphiboles from here. The normalization and naming of these amphiboles deviates significantly from good practice. Both 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 and Andy Tindle's xl spreadsheet Probe-Amph3.01 give a richterite composition of the analyses published as magnesio-riebeckite.
ⓘ Natrolite
Formula: Na2Al2Si3O10 · 2H2O
ⓘ Omphacite
Formula: (NaaCabFe2+cMgd)(AleFe3+fFe2+gMgh)Si2O6
ⓘ Richterite
Formula: Na(NaCa)Mg5(Si8O22)(OH)2
Description: Microprobe analyses from Wang et. al (2013) corresponds to the following formula: (Na1.105K0.051)1.156(Na0.970Ca1.03)2.00(Mg4.105Fe2+0.387Mn0.019Al0.262Ti0.015)4.788(Si7.977Al0.023)8.00O22(OH)2 Please note that A>1 and C<5, thus indicating that the analysis may be inaccurate.
ⓘ Winchite
Formula: ◻{CaNa}{Mg4Al}(Si8O22)(OH)2
Description: Wang et al (2013) publish 4 microprobe analyses of amphiboles from here. The normalization and naming of these amphiboles deviates significantly from good practice. Both 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 and Andy Tindle's xl spreadsheet Probe-Amph3.01 give a richterite composition of the analyses published as winchite.
