Geological Survey Professional Paper
Mineral assemblages are characterized by various combinations of quartz,
feldspar, hornblende, anthophyllite, gedrite, cummingtonite, garnet, biotite,
epidote, and diopside. Hornblende-an- thophyllite, gedrite-oligoclase, and
gedrite-garnet ...

U.S. Geological Survey professional paper
The orthorhombic amphibole gedrite occurs as a minor component in meta-
agglomerate of the Lightning Creek Schist just west of the bridge across the
Salmon River at Lake Creek. The gedrite is in part in monominerallic prisms,
variably ...

Geology and Regional Metamorphism of Some High-grade ...
In the Central City area, cordierite-gedrite gneiss forms slightly elongate bodies
parallel to the regional foliation that range in length from a few tens of feet to 300
feet and in width from a few feet to 100 feet. Most bodies are in direct contact with
...

High-Temperature Metamorphism and Crustal Anatexis
cordierite + staurolite + quartz = gedrite + sillimanite + H2O (9.9b) (Fig. 9.11,
cordierite is on the low-/5 side of the reaction curves) have been slightly modified
from the approximate P-T location given by Spear & Rumble (1986), as has the ...

Geological Survey Bulletin
South of the canyon, along the mountain front, the unit is more homogeneous
and seems to be principally a biotite-cordierite-garnet- gedrite gneiss, except that
in southernmost exposures it has a varied lithology and is poorer in gedrite.

Precambrian Geology of the Tobacco Root Mountains, Montana
This, along with the lack of crosscutting relationships, suggests that much of the
hornblende gneiss has been derived from mafic extrusive rocks probably
including some volcaniclastic sedimentary rocks. Anthophy Ilite-Gedrite Gneiss
and ...

CORDIEHITE-AMPHIBOLE GNEISS DISTRIBUTION AND CHARACTER Rocks
that contain cordierite and either gedrite or cummingtonite as principal
constituents were mapped as cordierite-amphibole gneiss. These rocks were first

Geology of Massachusetts and Rhode Island
A cordierite-gedrite schist occurs in a considerable layer in the Brimfield opposite
the school southwest of West Ware. The large well-twinned pleochroic cordierite
anhedra are associated with stout blades of hairlike brown gedrite like that on ...
