Olivine and quartz are rarely found together in igneous rocks due to their differing crystallization conditions and compositions. Olivine typically forms at higher temperatures in mafic and ultramafic magmas, while quartz crystallizes at lower temperatures in more silica-rich, felsic magmas. The presence of olivine usually indicates a more magnesium- and iron-rich environment, whereas quartz is associated with more silicon-rich compositions, making their coexistence in the same rock highly unlikely.
What else can I help you with?
What are the six minerals that make up igneous rocks?
Olivine, Pyroxene, Amphibole, Biotite, Muscovite, Potassium Feldspar, Quartz, Plagioclase are the minerals that make up the Igneous Rocks!:)another one is mica
Why are olivine and calcium-rich plagioclase often found together in igneous rocks?
Because both crystallize at similar temperatures and pressures according to Bowen's Reaction Series.
What does the minerals talcmuscovite mica quartz and olivine?
Talcmuscovite, commonly referred to as talc, is a soft mineral used in cosmetics and paper production. Mica, specifically muscovite, is a shiny mineral used in electronics and as a filler in various products. Quartz is a hard, crystalline mineral widely used in glassmaking, electronics, and jewelry. Olivine is a magnesium iron silicate often found in igneous rocks and is used in refractory materials and as a gemstone.
Where is quartz mostly found?
Quartz is mostly found in igneous and metamorphic rocks, such as granite and gneiss. It is also commonly found in sedimentary rocks, such as sandstone. Additionally, quartz can be found in hydrothermal veins and geodes.
Is quartz felsic?
Yes, quartz is felsic. Felsic minerals are rich in silica (SiO2) and aluminum (Al2O3), which are primary components of quartz. Quartz is commonly found in felsic igneous rocks such as granite and rhyolite.
Why would you would you not find quartz or olivine in the same igneous rock?
Quartz and olivine have different crystallization temperatures, with olivine forming at higher temperatures than quartz. This means that in most cases, olivine and quartz are not typically found together in the same igneous rock as they would have crystallized at different stages in the cooling process. Olivine is a common mineral in mafic rocks (rich in magnesium and iron) while quartz is more common in felsic rocks (rich in silica).
What is plagioclase feldspar with quartz and olivine?
Plagioclase feldspar is a common mineral in igneous rocks, while quartz is a mineral often found in a variety of rocks. Olivine is a green mineral commonly found in mafic igneous rocks. When all three minerals are present in a rock, it typically indicates a mafic igneous rock such as basalt or gabbro.
Are Olivine and quartz commonly found together in the same rock?
Yes, olivine and quartz are not commonly found together in the same rock. Olivine typically forms in mafic and ultramafic rocks like basalt and peridotite, whereas quartz is common in felsic rocks like granite. The two minerals have different chemical compositions and are usually associated with different rock types.
Is peridot a igneous rock or is it something else?
Peridot is a gemstone composed of the mineral olivine. Olivine is a common mineral found in igneous rocks such as basalt and peridotite. So, while peridot itself is not an igneous rock, it is closely associated with igneous rocks due to its mineral composition.
What are three main rocks found on this planet?
The three main rocks found on this planet are sedimentary, igneous, and metamorphic.
What are the six minerals that make up igneous rocks?
Olivine, Pyroxene, Amphibole, Biotite, Muscovite, Potassium Feldspar, Quartz, Plagioclase are the minerals that make up the Igneous Rocks!:)another one is mica
True or False Olivine and quartz commonly crystallize together from mafic or basaltic magmas?
false. SiO2 + CaMg(CaCO3)2 -> MgSiO4 + CaCO3 + CO2 (not balanced) Quartz + Dolomite -> Forsterite +Calcite + excess CO2 that is released as gas Forsterite is a type of olivine. Olivine's chemical formula is (Mg,Fe)SiO4, with the Mg as forsterite and the Fe as fayelite. Oceanic crust is rick in basalt and gabbro and these rocks have a very low quartz content or are void of it. Continental crust contains a large amount of granitic rocks from which quartz is found in most frequently. Olivine usually forms in very hydrous situations where there is water involved, and comes from oceanic crust usually.
Why are olivine and calcium rich plagioclase often found together in igneous rocks?
Olivine and calcium-rich plagioclase are often found together in igneous rocks because they have similar crystallization temperatures and are both common minerals in mafic igneous rocks. They are compatible minerals that can crystallize simultaneously from a cooling magma, leading to their coexistence in the same rock.
What two rocks are found in the outer core?
igneous quartz
Why are olivine and calcium-rich plagioclase often found together in igneous rocks?
Because both crystallize at similar temperatures and pressures according to Bowen's Reaction Series.
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.
