Geological Survey Professional Paper
Bowen finds 89 that quartz, where present, was most susceptible of replacement,
feldspars were the next mineral to be replaced, and aegirite was very resistant to
replacement. In quartz-bearing rocks the quartz had commonly been more ...

United States Geological Survey Professional Paper
Euhedral prisms of aegirite more than 2 centimeters long embedded in calcite
and arranged perpendicular to the walls in 1 vein suggest that open-vein filling
was a dominant process of vein formation. Abnormal radioactivity is found in at
least ...

Phenocrysts of greenish-black aegirite as much as 3 mm. long, most of which are
fresh and show zonal growth, occur In a small stock of Tertiary age on the south

Geology and Ore Deposits of the Tintic Mining District, Utah
The phenocrysts are plagioclase in well-formed laths and small irregular pitchy
black grains, which the microscope proves to be aegirite-augite. In thin section (
PL XVI, A, p. 78), the plagioclase is zonal and the zones range in composition
from ...

Fluorspar Prospects of Montana
The pyroxene observed during the present study is augite, possibly somewhat
soda-rich. Kemp and Billingsley 19 noted the presence of aegirite needles in the
groundmass, but aegirite was not found in the rock examined by the writer during
...

the earlier porphyritic pyroxenes is taken up by long needles of a paler diopside,
