Olivine weathers faster than quartz because it is less chemically stable when exposed to water and carbon dioxide in the atmosphere, leading to faster breakdown and weathering processes. Olivine is also more susceptible to chemical reactions and alteration compared to quartz, which is a more inert and resistant mineral.
What else can I help you with?
What elements combine to form pyrite?
Pyrite is composed of iron and sulfur atoms arranged in a crystal lattice structure. The chemical formula for pyrite is FeS2, indicating that each unit of pyrite contains one iron (Fe) atom bonded to two sulfur (S) atoms.
Are diamonds able to scratch quarts?
Yes, diamonds are harder than quartz on the Mohs scale, so diamonds can scratch quartz.
What is the independent variable of do colored candles burn faster than white candles?
The independent variable is the color of the candles - whether they are colored or white.
Are quartz and diamonds the same?
No, quartz and diamonds are not the same. Quartz is a mineral made of silicon and oxygen, while diamonds are made of carbon. Diamonds are harder than quartz and have different physical and chemical properties.
What is Quartz is rich in which element?
Quartz consists of silicon and oxygen (2 times as many oxygen atoms than silicon atoms).
Which would weather faster olivine or quartz?
Olivine would weather faster than quartz because it is less stable chemically and more prone to reactions with water and acids from the environment. Quartz, being a more resistant mineral, is more durable and less susceptible to weathering processes.
Is olivine more stable and weathering faster than quartz?
Following Goldich Dissolution Series (Or going backwards by Bowen's Reaction Series), olivine weathers before Quartz. Quartz has a framework silicate structure and olivine has a isolated silicate structure.
Does Olivine contain more silica than quartz?
No, quartz contains more silica than olivine. Quartz is made up of silicon dioxide (SiO2), which is about 46.7% silicon and 53.3% oxygen, while olivine is a magnesium iron silicate (Mg,Fe)2SiO4, containing less silica.
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).
Which mineral will scratch fluorite galena and pyroxene?
Quartz would be able to scratch fluorite, galena, and pyroxene as it is harder than these minerals on the Mohs scale of hardness.
What specific solid does sound travel through the fastest?
The denser the faster. ie: it will travel faster through quartz than sandstone.
What does this indicates A cubic centimeter of quartz olivine and gold weighs 2.5 3.0 and 19.8 grams respectively?
this indicates that gold is much more dense than quartz and olivine
Why does calcite weather faster then quartz?
Calcite weathers faster than quartz because it is more soluble in water. Calcite readily dissolves in acidic conditions, such as rainwater, leading to faster weathering compared to quartz, which is more resistant to chemical weathering due to its low solubility in water. Additionally, calcite has weaker chemical bonds that make it more susceptible to breakdown compared to quartz.
Why does granite or quartzite remain in boulder-sized pieces longer than older rocks that do not contain quartz?
Quartz is a mineral that is resistant to weathering due to its chemistry and crystalline structure. Granite will weather faster than quartzite because granite is only partially quartz in composition.
What are the main mineralogical differences between basalts and granites?
Basalts are higher in plagioclase feldspar, pyroxene, olivine and iron content than granites, which are typically higher in quartz, alkali feldspars, and micas.
Which will weather faster a rock containg a lot of iron or a rock made up mostly quartz?
A rock containing a lot of iron will likely weather faster than a rock made up mostly of quartz. Iron is prone to oxidation when exposed to moisture and oxygen, leading to rusting and faster deterioration compared to quartz, which is chemically more stable and less reactive.
How much gabbro is in olivine?
Olivine does not contain Gabbro. Gabbro can contain olivine. Usually no more than a few percent.
