an ultramafic composition
Is pyroxene a mineral or rock?
Pyroxene is a group of minerals.
Which mineral pyroxene or orthoclase crystallizes from magma first?
Usually pyroxene crystallizes from magma before orthoclase. Pyroxene has a higher melting point than orthoclase, so it will crystallize first as the magma cools and reaches temperatures where pyroxene can form.
Which ferromagnesian minerals and which of the feldspar's would be the first minerals to crystallize?
The first ferromagnesian mineral to crystallize is usually olivine, followed by pyroxene and amphibole. Among the feldspars, plagioclase feldspar is usually the first to crystallize, followed by potassium feldspar.
What type of rock is made of only pyroxene and olivine?
Peridotite is made only of olivine and pyroxene
Which rock is foliated shows mineral alignment but not banding and contains medium sized grains of quartz and pyroxene?
shist
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.
An igneous rock that contains mostly pyroxene and olivine has .?
an ultramafic composition
What igneous rock contains mostly pyroxene and olivine?
Ultramafic igneous rocks are comprised mostly of olivine and pyroxene. Examples include peridotite (pegmatic and porphyritic) and komatite.
What rocks does a gneiss rock contain?
Gneiss contains the minerals mica, quartz, feldspar, amphibole, garnet, and pyroxene.
What is a volcanic rock that contains pyroxene and has a fine grained texture?
A volcanic rock that fits your description is basalt. Basalt is dark-colored, fine-grained, and contains pyroxene minerals such as augite and pigeonite. It forms from the rapid cooling of lava on the Earth's surface.
Sand collected at a beach contains a mixture of pyroxene olivine amphibole and plagioclase feldspar . The rock from which this mixture of sand came is best described as?
The rock most likely belongs to the igneous category, such as a basalt that contains pyroxene, olivine, amphibole, and plagioclase feldspar.
Is pyroxene a mineral or rock?
Pyroxene is a group of minerals.
What minerals are in scoria?
Scoria typically contains minerals such as olivine, plagioclase, pyroxene, and magnetite. Additionally, it may also have glassy material resulting from the rapid cooling of the magma during its formation.
Is pyroxene good for arthritis?
No. Pyroxene is a crystalline silicate mineral.
Which mineral pyroxene or orthoclase crystallizes from magma first?
Usually pyroxene crystallizes from magma before orthoclase. Pyroxene has a higher melting point than orthoclase, so it will crystallize first as the magma cools and reaches temperatures where pyroxene can form.
