uralitic and brief extracts from same to provide context of its use in English literature.
Dark-green hornblende, largely uralitic (derived from pyroxene), is common and
is one of the chief minerals in some deposits. Pyrrhotite is the dominant mineral
in a deposit at Glennville, Calif. Pyrite is abundant in the deeper workings near ...

Uralitic <1abbro of Palmer Mountain. — In the exposure east of the head of
Palmer Lake this rock shows macroscopically a marked ophitic structure of rather
coarse grain. Microscopically the rock is found to consist essentially of
plagioclase ...

It is composed of planar distributed fine-grained biotite, generally intergrown with
uralitic amphi- bole. Quartz is completely recrystallized to form subgrains with
anastomosing boundaries and undu- lose extinction. In low-strain lenses, ...

ferromagnesian minerals are altered to garnet, biotite, chlorite, sericite, epidote,
and ealcite. Uralitic gabbros east of the Gold Hill fault are similar in composition
and have many sill-like relations to the volcanic-sedimentary rocks of the slate
belt ...

Geological Survey of Canada, Memoir 308
Original augite has been mostly replaced by uralitic hornblende, and plagioclase
feldspar by sodic plagioclase and epidote-group minerals. Further breakdown of
uralitic hornblende is generally to actinolite; in some cases augite and/or uralitic ...

Constitution Diagrams of Pennsylvania Anthracite
Under the microscope plagioclase, hornblende, augite, and accessory magnetite
and sphene can be seen as primary minerals, and actino- lite, tremolite, uralitic
hornblende, chlorite, zoisite, epidote, sericite, albite, calcite, pyrite, and prehnite ...

Geology of the Globe Copper District, Arizona
Every large mass of the diabase is made up in part of such uralitic facies, and
some of the smaller bodies are more or less uralitic throughout. Near the intrusive
contact of the diabase with other rocks, the former often exhibits well-marked ...

Diabasic dikes, herein described as fine-grained diorites, have been found in the
Mayari district and in other parts of Cuba. Keijzer (p. 64-65), described gabbroic
dike rocks including uralitic diabases and uralitic gabbro on the Rio ...

U.S. Geological Survey professional paper
The felsic layers consist mainly of calcic plagioclase (bytownite), whereas grains
of uralitic amphibole, some having residual augite cores, are abundant in the
dark-colored layers. Hornblende, magnetite, apatite, sphene, and locally bi- otite
