Magnesio-arfvedsonite from
Phakant Mine, Hpakant (Hpakan; Phakant; Phakan), Hpakant-Tawmaw Jade Tract, Hpakant Township (Hpakan; Phakant; Phakan), Mohnyin District, Kachin State, Myanmar
Locality type: | Mine | |
Classification | ||
---|---|---|
Species: | Magnesio-arfvedsonite | |
Formula: | {Na}{Na2}{Mg4Fe3+}(Si8O22)(OH)2 | |
Comments: | 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 | |
