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 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.
Identify three minerals that are normally found with quartz in samples of andesite rock?
Three minerals commonly found with quartz in andesite rock are feldspar (specifically plagioclase), biotite mica, and amphibole (such as hornblende). These minerals are all typically present in andesite as part of the overall composition of the rock.
Is quartz in Ohio?
Yes, quartz can be found in Ohio. It is commonly found in rock outcrops, riverbeds, and glacial deposits throughout the state. Quartz is a common mineral that can be found in many different types of rocks in Ohio.
Why are olivine and quartz never found together in an igneous rock?
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 is formed when Quartz and Feldspar are mixed together in nature?
Quartz and feldspar are commonly found together in granite and gneiss.
Would you find quartz and olivine in the same igneous rock?
Quartz and olivine typically do not occur together in the same igneous rock. Quartz is commonly found in felsic rocks, which are rich in silica, while olivine is prevalent in mafic and ultramafic rocks, which have lower silica content and are rich in magnesium and iron. The contrasting mineral compositions reflect different cooling histories and magma compositions. Therefore, while both minerals can be found in igneous rocks, they are usually indicative of different rock types.

Which mineral is not a typical mineral found in granite?
One mineral that is not typically found in granite is olivine. Granite is primarily composed of quartz, feldspar, and mica, while olivine is more commonly associated with mafic and ultramafic igneous rocks, such as basalt and peridotite. Thus, olivine's presence in granite would be unusual.
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 pyroxene most likely to be found in felsic rock?
No, olivine and pyroxene are more commonly found in mafic rocks due to their high iron and magnesium content. Felsic rocks, on the other hand, typically contain minerals like quartz, feldspar, and mica, which have lower iron and magnesium content.
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.
How are the mineral talc mica quartz and olivine are similar?
Talc, mica, quartz, and olivine are all silicate minerals, meaning they contain silicon and oxygen in their structures. They are commonly found in igneous, metamorphic, and sedimentary rocks and are important constituents of the Earth's crust. Each mineral has distinct physical properties and uses, but they share similarities in their crystalline structures and formation processes. Additionally, they all contribute to various geological processes and have industrial applications.
Is quartz in Ohio?
