Granite is a coarse grained igneous rock without Pyroxene.
What else can I help you with?
Which is a coarse-grained igneous rock composed of mainly pyroxene plagioclase feldspar and olivine?
Gabbro.
What is a coarse-grained rock composed of intermediate plagioclase feldspar and pyroxene?
The rock you are referring to is likely gabbro, which is a coarse-grained igneous rock composed mainly of intermediate plagioclase feldspar and pyroxene minerals. Gabbro forms from the slow cooling of molten magma deep within the Earth's crust, resulting in its coarse texture.
Which would weather faster a fine grained or a coarse grained igneous rock?
A fine-grained igneous rock would likely weather faster than a coarse-grained igneous rock. This is because the smaller grains in a fine-grained rock provide more surface area for weathering processes to act upon, leading to quicker breakdown and erosion.
How is gabbro formed?
Gabbro is a medium-grained, ultramafic igneous rock. It is made up of plagioclase feldspar and pyroxene. Gabbro is an intrusive igneous rock, meaning that it forms from the solidification of magma within the earth. Intrusive igneous rocks are medium- to coarse-grained because they cool slowly over time
What igneous rock has no visible crystals?
Obsidian is an igneous rock that has no visible crystals due to its rapid cooling process, which prevents crystal formation. It is often dark in color and has a glassy appearance.
Name a coarse grained igneous rock with no pyroxene?
Granite is a coarse grained igneous rock without Pyroxene.
Which is a coarse-grained igneous rock composed of mainly pyroxene plagioclase feldspar and olivine?
Gabbro.

Is Peridotite fine or coarse grained?
A peridotite is a dense, coarse-grained igneous rock
Do metamorphic rock and igneous rock have fine grained and coarse grained?
Yes. Exactly, they do have both, fine grained and coarse grained rocks.
What type of igneous rock has a coarse-grained texture?
pegmaitie
Which would weather faster a fine grained or a coarse grained igneous rock?
A fine-grained igneous rock would likely weather faster than a coarse-grained igneous rock. This is because the smaller grains in a fine-grained rock provide more surface area for weathering processes to act upon, leading to quicker breakdown and erosion.
What are two different igneous rock textures?
*fine-grained *coarse-grained

What is Earth's mantle made from?
It is made from a rock type known as Peridotite.Peridotite is an ultramafic dense, coarse-grained igneous rock consisting mostly of the minerals olivine and pyroxene containing less than 45% silica.
Peridotite is what type texture?
Peridotite is a dense, coarse-grained igneous rock.
