Rock-Forming Minerals: Orthosilicates, Volume 1A:
The possible exsolution origin of the willemite intergrowths in tephroite has been
discussed by Hurlbut. The tephroite-bearing manganese deposists of the United
States have been reviewed by Hewett et al. (1961); common assemblages ...

and rare at Sterling where tephroite is more widespread. Granite pegmatite
occurs at Franklin but has not been identified at Sterling Hill. Some of the

The Archaeometallurgy of Copper: Evidence from Faynan, Jordan
The oxidation in our light have also happened via a sudden oxygen input,
because Muan (1959b) istrated that tephroite is oxidized into Mn304 + braunite
or to Mn304 + rhodonite :low its liquidus at decreasing temperatures (<1204°C)
and ...
The degree of the increase of the absorbances at 600 and 400 nm of the
hydroquinone solution in the tephroite system is greatest, followed by actinolite,
hornblende, fayalite, augite, biotite, and muscovite = albite = orthoclase =
microcline ...

The sequence of the catalytic power of the primary minerals is: tephroite >
actinolite > hornblende, fayalite > augite > biotite > muscovite ≅ albite ≅
orthoclase ≅ microcline ≅ quartz (Shindo and Huang, 1985a). The degree of
acceleration of ...

The Chemistry of Weathering
The Birrimian metamorphic parent-rock consists roughly of 50 % tephroite, 35 %
spessartite garnet, 7.5 % quartz, 5 % manganocalcite , 2 % Mn-chlorite and 0.5 %
sul- f ides . These minerals respond differently to weathering. Thus, at the base ...

been identified at Sterling Hill. Some of the pegmatite apparently is earlier than
the ore and some later. The pegmatite is pink to gray and composed of quartz, ...
