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 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.
Where is hornblende mined?
Hornblende was originally found in Edenville, Orange County, New York. However, hornblende is a common mineral found in many different rock types and mined in place all over the world. For a map of localities, please refer to the related link.
What are some examples of how rock layers can become disturbed?
Their worldview could be unexpectedly challenged; for instance, schist may angrily accuse hornblende of cheating on feldspar with granite, whom hornblende fancied at university but never approached (until now). This could happen, for instance, if feldspar became too absorbed with work and took hornblende for granted, and schist, seeking to drive a wedge between hornblende and feldspar, made a series of unfortunate and tactless posts on hornblende's Rockbook wall.
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.
How much hornblende is in granite?
Hornblende is only an accessory mineral in granite, so its less than 5% of the total rock.

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 an igneous rock?
No, hornblende is a mineral commonly found in igneous rocks such as basalt and granite, but it is not a rock itself. Hornblende is a type of amphibole mineral that is typically dark green to black in color and is a common component of many igneous rock formations.

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.
