What clasts would you obtain if you crushed gabbro?
If you crushed gabbro, you would obtain clasts primarily composed of minerals such as pyroxene, plagioclase feldspar, and olivine. These minerals are common in gabbro, which is a coarse-grained igneous rock primarily made up of these mineral components.
Is gabbro a phaneritic rock?
Yes, gabbro is a phaneritic rock. It is an intrusive igneous rock with large crystals that are visible to the naked eye, typically composed of minerals such as plagioclase feldspar and pyroxene.
What minerals could you find in a gabbro?
You can find minerals such as plagioclase feldspar, pyroxene, and olivine in gabbro. These minerals are typically dark in color and have a crystalline structure due to the slow cooling process of gabbro forming beneath the Earth's surface.
Can gabbro contain mineral quartz?
No, gabbro does not typically contain mineral quartz. Gabbro is a coarse-grained igneous rock composed primarily of calcium-rich plagioclase feldspar and pyroxene minerals. Quartz is not a common mineral in gabbro; it is more common in granitic rocks.
What type of rock may be formed by fractional crystallization of olivine and pyroxene.?
A mafic rock, such as gabbro or basalt, may be formed through fractional crystallization of olivine and pyroxene. Mafic rocks are characterized by their high content of magnesium and iron, which are common components of olivine and pyroxene minerals.
What is the percentage of olivine in gabbro?
The percentage of olivine in gabbro is typically low, ranging from 0-10%. Olivine is not a common mineral in gabbroic rocks, which are primarily composed of pyroxene, plagioclase feldspar, and sometimes amphibole.
Which minerals are found in basalt and gabbro?
Basalt contains minerals such as plagioclase feldspar, pyroxene, and olivine. Gabbro also contains plagioclase feldspar and pyroxene, but generally has a coarser texture due to slower cooling rates underground.
What clasts would you obtain if you crushed gabbro?
If you crushed gabbro, you would obtain clasts primarily composed of minerals such as pyroxene, plagioclase feldspar, and olivine. These minerals are common in gabbro, which is a coarse-grained igneous rock primarily made up of these mineral components.
Which minerals are found in the igneous rocks gabbro and basalt?
Gabbro and basalt are both mafic igneous rocks and contain minerals such as pyroxene, plagioclase feldspar, and olivine. Gabbro typically has a coarser grain size compared to basalt, which has a fine-grained texture due to its rapid cooling at the Earth's surface.
Is gabbro a phaneritic rock?
Yes, gabbro is a phaneritic rock. It is an intrusive igneous rock with large crystals that are visible to the naked eye, typically composed of minerals such as plagioclase feldspar and pyroxene.

Can gabbro contain mineral quartz?
No, gabbro does not typically contain mineral quartz. Gabbro is a coarse-grained igneous rock composed primarily of calcium-rich plagioclase feldspar and pyroxene minerals. Quartz is not a common mineral in gabbro; it is more common in granitic rocks.
Which is a coarse-grained igneous rock composed of mainly pyroxene plagioclase feldspar and olivine?
Gabbro.
Is gabbro a foliated or nonfoliated rock?
Gabbro is a nonfoliated rock, meaning it does not have a layered structure like foliated rocks such as slate or schist. Gabbro is a coarse-grained, intrusive igneous rock composed mainly of pyroxene, plagioclase feldspar, and sometimes olivine.
Does gabbro have a streak?
Gabbro does not have a streak because it is a coarse-grained rock made up of minerals like plagioclase feldspar and pyroxene that are harder than the streak plate. As a result, gabbro does not leave a streak when rubbed on a streak plate.
Can gabbro contain the moneral quartz?
No, gabbro typically does not contain quartz. Gabbro is a coarse-grained, dark-colored intrusive igneous rock composed mainly of calcium-rich plagioclase feldspar and pyroxene minerals. Quartz is not a common mineral in gabbro due to its typically silica-poor composition.
What type of rock is gabbro?
Gabbro is an intrusive igneous rock that is coarse-grained and dark in color. It is primarily composed of calcium-rich plagioclase feldspar and pyroxene minerals. Gabbro is the plutonic equivalent of basalt.
