Foliated rocks can be identified by their layered or banded appearance, which is caused by the alignment of mineral grains in a preferred orientation. They often show visible mineral grains like mica or chlorite, and can split into thin sheets or layers due to their parallel alignment. Foliated rocks are commonly found in metamorphic environments where intense heat and pressure have altered the original rock.
Aquamarine is a form of the mineral beryl.
The black in igneous and metamorphic rocks could be any of numerous black minerals. Two that are commonly found are biotite mica and hornblende.
The ore of mica is called "muscovite." It is a type of mica mineral that is commonly found in metamorphic and igneous rocks. Muscovite is known for its pearlescent luster and excellent cleavage properties.
Large mineral crystals are commonly found in igneous rocks, such as granite and pegmatite, where slow cooling allows minerals to grow large. Certain metamorphic rocks, like marble and schist, can also contain large mineral crystals due to high pressures and temperatures. Veins and pockets within rocks can sometimes host large crystals as well.
Metamorphic rock with mineral grains arranaged in bands or lamellar planes are called foliated metamorphic rocks.

No, sodalite is a metamorphic mineral, not a rock. It is a blue mineral commonly found in igneous rocks like syenite or nepheline syenite.
The mineral commonly found in all three metamorphic rocks slate, schist, and gneiss is mica. Mica is a group of minerals known for their perfect cleavage, flexibility, and mineral composition, which make them prevalent in metamorphic rocks.
Fluorite is a commonly found mineral that forms from hydrothermal processes and is often associated with rocks of various origins, including sedimentary, igneous, and metamorphic rocks. While it can be found in metamorphic environments, fluorite itself is not considered a metamorphic rock.
Biotite is definitely a mineral. It's in the same family as muscovite, another mineral in the mica family.
Hornblende is a mineral, specifically a silicate mineral belonging to the amphibole group. It is commonly found in igneous and metamorphic rocks.
Calcite is a mineral commonly found in sedimentary rocks. It can also be found in some metamorphic rocks, as it can recrystallize under heat and pressure. It is unlikely to be found in igneous rocks except in trace amounts.
Aquamarine is a form of the mineral beryl.
A pyroxene is any of a group of crystalline silicate mineral common in igneous and metamorphic rocks.
Feldspar is primarily an igneous rock-forming mineral, commonly found in intrusive and extrusive igneous rocks such as granite and basalt. However, feldspar can also be present in some metamorphic rocks as a result of the recrystallization of pre-existing feldspar minerals during metamorphic processes.
The black in igneous and metamorphic rocks could be any of numerous black minerals. Two that are commonly found are biotite mica and hornblende.
