He also held the post of President for both the the Crystallographic Society of Japan and the Mineralogical Society of Japan.\r\n\r\nSadanagaite was first described as a new silica-poor amphibole (IMA 1980-027), published by Shimazaki et al. (1984). It was redefined in the 1997 amphibole nomenclature (Leake et al., 1997). The original definition of sadanagaite has K>Na in the A position, this was reversed in 1997. It should also be noted that there is a probable typo in the 1997 nomenclature report, defining sadanagaite with Fe\u003Csup>3+\u003C\u002Fsup>>Al in the formula, which has led some authors to use the term aluminosadanagaite (see Nikandrov et al., 2001).\r\n\r\nSadanagaite was again redefined in the 2012 amphibole nomenclature to be the Na-, Mg- and Al-dominant member of the sadanagaite group (Hawthorne et al., 2012).\r\n\r\nConsequently, the material originally described as sadanagaite in 1984, became potassic-sadanagaite in 1997 and potassic-ferro-sadanagaite in 2012. \r\n\r\nNa- and Fe\u003Csup>2+\u003C\u002Fsup>-dominant material described as sadanagaite between 1997 and 2012 is now (2012) ferro-sadanagaite. \r\n\r\nThe material described by Banno et al.
