Metamorphic rock - Wikipedia

Metamorphic rocks are one of the three great divisions of all rock types, and so there is a great variety of metamorphic rock types. In general, if the protolith of a metamorphic rock can be determined, the rock is described by adding the prefix meta-to the protolith rock name. For example, if the protolith is known to be basalt, the rock will be described as a metabasalt.

Amphibolite | rock | Britannica

Amphibolite, a rock composed largely or dominantly of minerals of the amphibole group. The term has been applied to rocks of either igneous or metamorphic origin. In igneous rocks, the term hornblendite is more common and restrictive; hornblende is the most common amphibole and is typical of such rocks. Hornblendite is an ultramafic rock (dominantly dark minerals).

amphibole | mineral | Britannica

The term biopyribole has been used to describe any mineral that has both I beams and sheetlike structures. The name comes from biotite (mica), pyroxene, and amphibole. Biopyriboles have chain widths and repeat sequences like pyroxenes (single-chain repeats), amphiboles (double-chain repeats), and triple-chain repeats.

Hornblende Mineral | Uses and Properties

The mineral hornblende has very few uses. Its primary use might be as a mineral specimen. However, hornblende is the most abundant mineral in a rock known as amphibolite which has a large number of uses. It is crushed and used for highway construction and as railroad ballast. It is cut for use as dimension stone.

Amphibolite - Meanings List

Amphibolite has the meaning and properties of an amulet against evil. It is a gemstone to strongly block surrounding negative energy. It is also used when you want to break an unfortunate flow. It is a valuable amulet such as when you want to strengthen the defense of life.

Wisconsin Geological & Natural History Survey » Hornblende

Some of the amphibolite has been used to make bookends, tie tacks and pendants. (Lovvik, 1976). FLORENCE COUNTY: Hornblende is a major constituent of amphibolite and hornblende schist in the Quinnesec Formation throughout the county. It is in grains up to 0.5 mm in diameter, associated with oligoclase, biotite and quartz (Dutton, 1971).


For example, use "horn-blende schist" or "amphibolite" instead of "sericite-chlorite-calcite-hornblende schist." The term "granite" may be used as the rock name and conveys more to the designer than the petrographically correct term "nepheline …

Amphibole | Minerals Education Coalition

As noted above, amphibolite is used locally where it is easily quarried, reducing the costs of transporting rock in from other regions. There are many options to amphibolite as dimension stone. Marble, granite, and quartzite, for instance, can all be polished and used as facing on the interior and exterior of buildings.

Amphibolite is largely composed of long, thin crystals of amphiboles aligned in a common direction. Sometimes separate light bands of feldspar are evident. Amphibolite forms through metamorphism of mafic igneous rocks. 6. If metamorphism reaches a temperature > 700 o C, rocks may begin to partially melt.
