Locality type:Mine
Classification
Species:Ferro-gedrite
Formula:◻{Fe22+}{Fe32+Al2}(Al2Si6O22)(OH)2
Comments:Published is sodimu rich, and the composition corresponds to ferro-gedrite or sodic-ferrogedrite based on natural chemical variation in the amphibole, but also based on the method used to normalize the formula. Locock (2014) give ferro-gedrite for all samples pubilshed by Matsubara et al. (1980)
