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 found in both igneous and metamorphic rocks and can be recognized by its colour and prismatic shape.
Is Gabbro iron rich?
Yes. Gabbro, an igneous rock, has iron-bearing hornblende and augite.
How do igneous rocks like granite form?
Igneous form when molten rock cools and solidifies. Granite is an intrusive igneous rock, meaning it forms when molten rock cools deep underground. There are also extrusive igneous rocks, which cool on the surface after erupting from a volcano.
What metamorphic rock is formed by dolerite?
hornblende

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.
How is hornblende made?
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.
Where is hornblend found?
Hornblende is found in both igneous and metamorphic rocks and can be recognized by its colour and prismatic shape.
Is Gabbro iron rich?
Yes. Gabbro, an igneous rock, has iron-bearing hornblende and augite.
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.
Is hornblende a rock or mineral?
Hornblende is a series of dark minerals.
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.
What mineral does magma turn into when it cools?
Magma solidifies into a combination of minerals that are collectively called igneous rock. Minerals common in igneous rock are potassium feldspar, plagioclase feldspar, muscovite and biotite mica, quartz, hornblende, olivine, and magnetite.
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)
How do igneous rocks like granite form?
Igneous form when molten rock cools and solidifies. Granite is an intrusive igneous rock, meaning it forms when molten rock cools deep underground. There are also extrusive igneous rocks, which cool on the surface after erupting from a volcano.
What class of rock is hornblende?
