The dark, prismatic crystal known as hornblende is a common constituent of quite a few igneous and metamorphic rocks. This includes not only granite, but also schist, syenite, gabbro, diorite, andesite, basalt, and gneiss. The word hornblende itself is in reference to it's similarity in appearance to metal-bearing ore minerals.

What type of rock is hornblende diorite?
Hornblende diorite is a type of intrusive igneous rock. It is composed primarily of plagioclase feldspar, hornblende, and small amounts of other minerals. It has a medium to coarse-grained texture and is typically gray or greenish in color.
Where is hornblend found?
Hornblende is a common mineral found in a variety of igneous and metamorphic rocks, including granite, diorite, and gneiss. It can also be found in some hydrothermal veins and as a constituent of some skarn deposits. Hornblende is widespread and can be found in many locations worldwide.
Is diorite a rock?
Yes, diorite is a type of rock. It is a granular igneous rock that is commonly found in mountain ranges and other geologically active areas. Diorite is composed mainly of plagioclase feldspar, biotite, hornblende, and other minerals.
What color rock is syenite?
Igneous Rock
What are the special properties of hornblende?
Hornblende is a mineral group that typically has a dark color with two cleavage directions at nearly 60 and 120 degrees. It is commonly found in igneous and metamorphic rocks, and its composition includes calcium, magnesium, iron, aluminum, and silica. Hornblende is an important mineral in geology due to its role in understanding the conditions of rock formation and metamorphism.
What type of rock is hornblende diorite?
Hornblende diorite is a type of intrusive igneous rock. It is composed primarily of plagioclase feldspar, hornblende, and small amounts of other minerals. It has a medium to coarse-grained texture and is typically gray or greenish in color.
Is hornblende a rock or mineral?
Hornblende is a mineral, specifically a silicate mineral belonging to the amphibole group. It is commonly found in igneous and metamorphic rocks.
What will a rock look like when hornblende is added?
It will look like greenish to blackish color and will be a part of igneous rock.
What class of rock is hornblende?
Hornblende is a mineral commonly found in igneous and metamorphic rocks. It belongs to the amphibole group of minerals, which are inosilicates with a double-chain structure. Hornblende is dark green to black in color and can form large crystals in certain rock types.
What is amphibolite made of?
Amphibolite is a type of metamorphosed mafic igneous rock. It is composed largely of minerals such as hornblende and plagioclase.
Where is hornblend found?
Hornblende is a common mineral found in a variety of igneous and metamorphic rocks, including granite, diorite, and gneiss. It can also be found in some hydrothermal veins and as a constituent of some skarn deposits. Hornblende is widespread and can be found in many locations worldwide.
Is diorite intrusive or extrusive?
Diorite is an intrusive igneous rock, formed from the cooling and solidification of magma beneath the Earth's surface. It contains a mix of minerals such as plagioclase feldspar, biotite, hornblende, and pyroxene.
Is a gabbro a intrusive rock or a extrusive rock?
it is an intrusive igneous rock with composition equivalent of basalt.it is dark colored due to high concentration of dark minerals;olivine,biotite,hornblende.
Is diorite a rock?
Yes, diorite is a type of rock. It is a granular igneous rock that is commonly found in mountain ranges and other geologically active areas. Diorite is composed mainly of plagioclase feldspar, biotite, hornblende, and other minerals.
How is hornblende made?
Hornblende forms as a result of solidification of magma deep within the Earth's crust. It typically crystallizes in igneous rocks like granite and diorite, where it cools slowly allowing for the growth of large crystals. Hornblende can also be found in some metamorphic rocks that have undergone high temperatures and pressures.
What color rock is syenite?
Igneous Rock
What describes an andesite?
Andesite are fine-grainedextrusive, igneous volcanic rock composed essentially of plagioclase feldspar and one or more mafic minerals, such as hornblende, pyroxene or biotite.(Refer to Geology.com -Igneous Rocks)
