UM1995-05-E:FeMn (original) (raw)

Invalid as an unnamed mineral

First Fe-Mn alloy mineral reported.

Reported as "the manganese analog of taenite".

As lamellar grains, up to 0.8 mm in length, in (1) eruptive breccia or (2) a high temperature exhalative product.

Electron microprobe results, wt.% (mean of 6 analytical points): Fe 83.91, Mn 13.01
(11.82-15.17), Cr 0.24, Si 0.73, total 97.90.

Opaque with metallic luster, white in reflected light, isotropic. Reflectance data also reported.

Note: V.A. Kovalenker suggests this phase is a Mn-bearing variety of taenite rather than its analogue.
