Hornblende is a complex inosilicate series of minerals. It is not a recognized mineral in its own right, but the name is used as a general or field term...

Ellery, the Hornblende Bluffs, Heth Ridge and Mount Send are to the west. To the north, near its mouth, it passes Northrup Head, Whited Inlet and Belousov...

often small grains of hornblende. Extensive recrystallization often goes on, and the ultimate product is a spotted rock with white rounded patches of scapolite...

orthoclase, and both feldspars — orthoclase and plagioclase — are white. Hornblende is rare, compared to other Yosemite granites. Most black minerals...

also extends towards hornblende and arfvedsonite. There is not a continuous series between calcic clinoamphiboles, such as hornblende, and low-calcium amphiboles...

silicate minerals plagioclase feldspar (typically andesine), biotite, hornblende, and sometimes pyroxene. The chemical composition of diorite is intermediate...

(/æmˈfɪbəlaɪt/) is a metamorphic rock that contains amphibole, especially hornblende and actinolite, as well as plagioclase feldspar, but with little or no...

with a large garnet crystal (black) in a matrix of quartz and feldspar (white and gray grains) and parallel strands of mica (red, purple and brown). View...

actinolite and chlorite. This gives way to hornblende, plagioclase, pyroxene, and garnet in the hornblende hornfels facies, which in turn gives way to...

minerals, usually hornblende, pyroxene or a feldspar mineral, and may need to be named after their phenocryst mineral, such as 'hornblende-bearing felsite'...

the Blue Ridge Mountains of Virginia. Plagioclase phenocrysts (white) and hornblende phenocryst (dark; intergrown with plagioclase) are set in a fine...

contains biotite and plagioclase. Vogesite contains hornblende and orthoclase. Spessartite contains hornblende and plagioclase. Monchiquite contains no feldspar...

feldspar and quartz with scattered darker biotite mica and amphibole (often hornblende) peppering the lighter color minerals. Occasionally some individual crystals...

(variety of fluorite) Anyolite (metamorphic rock - zoisite, ruby, and hornblende) Aquamarine (light blue variety of beryl) Argentite (high temperature...

growth, but rather through the mixture of chalcedony and oxidized iron hornblende. Dendritic agate also displays vegetative features, including fern-like...

contains only hornblende, has the same composition as some of the camptonites of the same locality that contain feldspar and hornblende of a different...

suite. There is a moderate quantity of phenocrysts, including biotite, hornblende, ilmenite, hypersthene, magnetite and plagioclase, with little apatite...
