Geological Studies in the Klamath Mountains Province, ...
Contact metamorphism was chiefly under hornblende-hornfels–facies conditions
and grades into the regional greenschist-facies metamorphism characteristic of
this part of the Klamath Mountains (Coleman et al., 1988). The Bear Peak ...

Rock-forming Minerals in Thin Section
Alteration: rare in volcanic rocks, where green hornblende can be replaced by
brown hornblende, due to oxidation of Fe2* to Feu (-»oxyhornblende). This
process can be accompanied by a partial or complete opacitization (Part B,
section ...
Hans Pichler, Cornelia Schmitt-Riegraf, 1997

Petrologic and Structural History of Tobago, West Indies: A ...
The fabric is defined by tabular plagioclase and hornblende prisms, whereas
interstitial quartz is anhedral and only weakly strained. This fabric thus is chiefly
of magmatic origin developed early in the crystallization history, although local ...

The rocks contain small phenocrysts of albite some of which have been changed
to sericite and epidote, and aggregates of blue-green hornblende usually
crowded with magnetite inclusions, set in a granular groundmass of albite,
hornblende, ...
The mineralogy consists of ortho- and clinopyroxene, garnet, K-feldspar,
plagioclase, quartz, biotite and hornblende, that, together with textural evidence,
indicates the association is in part the result of the decomposition reactions: ...

Natural Hazards in El Salvador
Hornblende phenocrysts exhibit textures that could also be explained by a
heating event. The dehydration reaction of hornblende, producing an anhydrous
assemblage of plagioclase, pyroxenes, and Fe- Ti oxides, may occur in response
to ...

(CasoMgsgFea), shows schiller inclusions, and is overgrown and partially
replaced with hornblende (2K« = 79°, 7=1-678) and together clinopyroxene and
hornblende constitute approximately 37% of the rock by volume. Ores are
abundant ...

Precambrian Geology of the Tobacco Root Mountains, Montana
associated with thin layers of quartzofeldspathic gneiss and other rock types
including thin lenses of marble. The total thickness of the hornblende gneiss is
about 2.5 to 3 km. The hornblende gneiss units are readily distinguished, by their
grain ...

Ophiolites in Earth History
It cuts the harzburgite and high-level gabbros (Fig. 2), which contain flattened
and stretched hornblende and plagioclase grains that display a strong S-C fabric
(Lister & Snoke 1984). The stretching lineation, defined by hornblende- and ...
