(Belongs to Ehime prefecture, but closest city is Innoshima in Hiroshima prefecture, leading to erroneous labels assigning Yuge to Hiroshima.) Al-Ti-Fe-rich skarn in marble bed in a limestone quarry.

Shimazaki et. al.(1984) used material from Yuge in the type description of sadanagaite and magnesiosadanagaite. The sadanagaite-group minerals has been redefined twice sine this paper, latest by Hawthorne et.al (2012). By reviewing Shimazaki's analysis (Electron microprobe), using the software published by Oberti et al. (2012) for identification, the following amphiboles are present:

Potassic-ferro-rootname4:

(Na0.170K0.690)(Na0.020Ca1.970Mn0.010)(Mg1.520Fe2+1.600Mn2+0.040Al0.850Fe3+0.480Ti4+0.510)(Si4.770Al3.230)(O22(OH)2.000)

Potassic-ferro-sadanagaite
(Na0.290K0.710)(Ca2.000)(Mg1.500Fe2+1.550Mn2+0.020Al1.070Fe3+0.400Ti4+0.460)(Si4.61Al3.390)(O22(OH)2.000)

Potassic-ferri-sadanagaite
(Na0.200K0.680)(Ca1.960Mn0.040)(Mg1.750Fe2+1.130Al0.710Fe3+0.970Ti4+0.460)(Si4.520Al3.480)(O22(OH)2.000)

The software operates with 4 valid digits as a standard, and this does not necessarily reflect the accuracy of the original analysis,

Any references to other sadanagaite-group minerals should be validated by micropobe data.
