Amphibolite is a rock in which "Basalt" or "Gabbro" has changed. It changes in "hot" and "high pressure" environments deep underground. It is a type of rock called "Metamorphic Rock". Amphibolite is a rock formed …
Amphiboles are only one of the mineral sources for jade and asbestos though. Some jade is formed of a pyroxene mineral, while most modern asbestos is mined from chrysotile, a fibrous variety of serpentine. Description and Identifying Characteristics
The amphibolite sample (11JG-13b) with anomalously low δ 66 Zn (−0.07 ± 0.03‰) is characterized by higher δ 26 Mg (−0.11 ± 0.04‰; Wang et al., 2016) than that of the mantle (δ 26 Mg = −0.25 ± 0.04‰, Teng et al., 2010) (Fig. S4c). We suggest that the igneous protolith of this sample was likely derived from a mantle source ...

At lower degrees of metamorphism it grades into amphibolite. Granulite can be a very attractive rock and is often used for countertops (pictured). Unfortunately, it is usually mislabeled as 'granite' when being sold to consumers. Non-Foliated Non-foliated metamorphic rocks are one of two major groups of metamorphic rocks.

Both important tools in mineral exploration can then be used in a more targeted and cost-effective way. Petrophysical parameters measured on drill core and field samples and acquired through geophysical borehole logging are compiled in the first database for European Pegmatite deposits: EuroPeg_PetroDB. ...

Amphibolite has a variety of uses in the construction industry. It is harder than limestone and heavier than granite. These properties make it desirable for certain uses. Amphibolite is quarried and crushed for use as an aggregate in highway construction and as a ballast stone in railroad …
An important group of rock-forming minerals in igneous and metamorphic rocks, amphiboles share a similar crystal structure and cleavage pattern, but contain different proportions of sodium (Na), calcium (Ca), iron (Fe) and magnesium (Mg), which substitute for one another in its crystal structure. Amphibole minerals are generally dark-colored ...
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 …
Although hard to see, the specimen contains native gold near the bottom of the sample. If you enlarge the photo you can see the gold. At still higher grade, chlorite, epidote, and actinolite break down by dehydration reactions, producing a specific kind of rock called an amphibolite. The photo in Figure 8.67 is an example.
What kind of uses can amphibolite be used for? These properties make it desirable for certain uses. Amphibolite is quarried and crushed for use as an aggregate in highway construction and as a ballast stone in railroad construction. It is also quarried and cut for use as a dimension stone. What makes amphibolite a popular dimension stone?
In antiquity, amphibolite was carved into sculpture. Modernly, this durable material is commonly used in cemetery markers, commemorative tables and public art. …
The study samples form a continuum in terms of textural relationships and mineral compositions, but they can be divided into three main types: metagabbro, lineated metagabbro, and amphibolite. Metagabbro samples preserve both relict igneous and metamorphic textures and a combination of igneous and metamorphic mineralogy.
The Amphibole crystal you mention looks to be one from China, It is a pink Hematite Included Quartz crystal, so the color is provided by the Hematite itself. Check out the hematite properties page at https://crystal-information.com/encyclopedia/hematite-properties-and-meaning/
Amphibolite. Amphibolite is a common metamorphic rock. It is made of amphiboles (usually hornblende) and plagioclase. Most samples have a relatively simple composition: hornblende + plagioclase. Garnet (almandine), pyroxene, biotite, titanite, magnetite, epidote, chlorite, and quartz are also frequent constituents.
The following are the physical properties and chemical characteristics of the amphibole mineral: Amphibole is made up of double chains of silica in a tetrahedral structure with both the chains being linked to each other at their vertices. The crystalline structure of the amphibole contains ions of iron and/or magnesium within it.
The protolith for an amphibolite must be a rock type with a large amount of dark ferromagnesian minerals, such as a mafic or ultramafic igneous rock. Amphibolites require higher temperatures and pressures to form as well and are considered to be high-grade metamorphic rocks.
Geochemical studies indicate that the protolith of these amphibolites is calc-alkaline island arc basalt, which was formed during the reconstruction of the Paleo-Middle Archean crust on the northern margin of the Yangtze Block 2,362 ± 100 Ma ago (equivalent to metamorphic rocks of the Yudongzi group).
Amphibolite is a gneissose or granofelsic metamorphic rock mainly consisting of green, brown or black amphiboleand plagioclase(including albite), which combined form ≥75% of the rock and both of which are present as major constituents; the amphiboleconstitutes ≥50% of the total mafic constituents and is present in an amount of ≥30%.
Aluminum can partially substitute for silicon in the tetrahedral (T) site. Partial substitution of fluorine (F), chlorine, and oxygen for hydroxyl (OH) in the hydroxyl site is also common. The complexity of the amphibole formula …

The term is very commonly used to describe the fibrous form of Chrysotile Serpentine, and may also be used in regards to the fibrous variety of Tremolite or Actinolite. Asbestos Amphibole - Describes any finely fibrous mineral of the amphibole group, especially Tremolite and Actinolite. Byssolite
epidote-amphibolite facies, one of the major divisions of the mineral-facies classification of metamorphic rocks, the rocks of which form under moderate temperature and pressure conditions (250°–400° C [500°–750° F] and up to 4 kilobars [1 kilobar equals about 15,000 pounds per square inch]).

Amphibolite is a common metamorphic rock that forms through the high-grade metamorphism of mafic rocks. It is characterized by the presence of amphibole minerals, typically hornblende and/or actinolite. These minerals give amphibolite its typical dark greenish-black color. Metamorphic means "changed form," and amphibolite is a good …
Amphibolite is a grouping of rocks composed mainly of amphibole (as hornblende) and plagioclase feldspars, with little or no quartz. It is typically dark-colored and heavy, with a weakly foliated or schistose (flaky) structure. The small flakes of black and white in the rock often give it a salt-and-pepper appearance.
