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.
hornblende
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.
Yes. Gabbro, an igneous rock, has iron-bearing hornblende and augite.
Diorite is a light to dark grey rock comprised mostly of biotite, hornblende, proxene and plagioclase feldspar (more often than not, andesine). Diorite is a relatively rare form of rock.
Hornblende is a series of dark minerals.

Hornblende is only an accessory mineral in granite, so its less than 5% of the total rock.
Hornblende is a common mineral found in igneous and metamorphic rocks. The crystals form from the consolidation of elements found in the magma or parent rock.
It will look like greenish to blackish color and will be a part of igneous rock.
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.
