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 else can I help you with?
Is hornblende attracted to magnet?
Hornblende is not attracted to magnets because it is primarily composed of silicate minerals and does not possess significant magnetic properties. While it may contain some iron, the overall mineral structure does not exhibit magnetism. Thus, hornblende is considered non-magnetic.
What color is hornblende's streak?
Hornblende's streak color is typically white to gray.
What is hornblende's hardness?
the hardness scale for the mineral hornblende is 5-6.
Is hornblende metallic?
Hornblende is not metallic; it is a complex silicate mineral that belongs to the amphibole group. It typically exhibits a dark color, often black or green, and has a glassy to dull luster. Its composition includes iron, magnesium, and calcium, which contribute to its properties, but it lacks the characteristic shine and conductivity associated with metallic minerals.
Can hornblende be scratched from a fingernail?
Hornblende is a mineral with a hardness of about 5 to 6 on the Mohs scale, which means it is harder than a fingernail, which has a hardness of about 2.5 to 3. Therefore, hornblende cannot be scratched by a fingernail. Instead, a fingernail would likely be scratched by hornblende if they came into contact.
Is hornblende magnetic?
No, hornblende is not a magnetic mineral. It does not exhibit any magnetic properties.

What color is hornblende's streak?
Hornblende's streak color is typically white to gray.
What is the Mining Process of Hornblende?
Hornblende is a mineral commonly found in metamorphic and igneous rocks and is not mined directly. If hornblende-bearing rocks are mined for other minerals, the hornblende may be extracted during the processing of the ore. Hornblende itself does not have any industrial uses that require specific mining processes.
What is hornblende's hardness?
the hardness scale for the mineral hornblende is 5-6.

Therefore, hornblende cannot be scratched by a fingernail. Instead, a fingernail would likely be scratched by hornblende if they came into contact.
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 is the definition of special properties?
The definition of special properties are the unique features of a substance. They are commonly derived from other intrinsic and extrinsic properties.
Does granite have hornblende?
Yes
What are the properties of marbles?
Usually , marble contains several other minerals besides calcite. Others such as hornblende and serpentine give it a black or green tone. Hematite makes it red.
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.
