Name:
Named in honor of Ryoichi Sadanaga (定永両一) (25 June 1920, Osaka, Japan - 17 January 2002), crystallographer and professor of the Mineralogical Institute, University of Tokyo. He also held the post of President for both the the Crystallographic Society of Japan and the Mineralogical Society of Japan.
Sadanagaite 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 Fe3+>Al in the formula, which has led some authors to use the term aluminosadanagaite (see Nikandrov et al., 2001).
Sadanagaite 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).
Consequently, the material originally described as sadanagaite in 1984, became potassic-sadanagaite in 1997 and potassic-ferro-sadanagaite in 2012.
Na- and Fe2+-dominant material described as sadanagaite between 1997 and 2012 is now (2012) ferro-sadanagaite.
The material described by Banno et al. (2003) as magnesiosadanagaite was defined as sadanagaite in the 2012 ampibole nomenclature.

Interference Colours:
The colours simulate birefringence patterns seen in thin section under crossed polars. They do not take into account mineral colouration or opacity.
Michel-Levy Bar The default colours simulate the birefringence range for a 30 µm thin-section thickness. Adjust the slider to simulate a different thickness.
Grain Simulation You can rotate the grain simulation to show how this range might look as you rotated a sample under crossed polars. Each grain retains its interference colour (retardation) while its brightness falls to black at extinction and reaches a maximum between extinction positions.

This shows the grain boundary and Becke line effect under plane-polarised
light, based on the contrast between this mineral's average refractive
index and the mounting medium. It does not take into account mineral
colouration.
In focus
Interference Figure:
This shows the idealized biaxial acute bisectrix (Bxa) interference figure
- the conoscopic view for a grain cut perpendicular to the acute bisectrix, using
this mineral's 2V. The two small white dots mark the melatopes - the points
where the two optic axes emerge - and are shown only when they fall within the
field of view. The coloured bands are isochromatics, and the dark bands are
isogyres.
Rotate the stage: at 0°/90° the isogyres form a cross through the melatopes; at 45° they pull apart into curved hyperbolas. That splitting on rotation - absent in a uniaxial figure - is the standard diagnostic test for telling biaxial minerals from uniaxial ones. If 2V is large, the melatopes may fall outside the field of view, as they often do at the microscope too.
