What elements combine to form pyrite?
A pyroxenite is an ultramafic rock composed mainly by clinopyroxene, orthopyroxene and in minor amount, olivine (less than 40%). Depending of the modal mineralogy, the can be subclassified as orthopyroxenite (90% or more of opx), clinopyroxenite (90% or more than cpx), websterite (10% or less of olivine) and olivine-websterite (10-40% of olivine). Because the composition of these mineral phases is highly variable, pyroxenites have a broad range of compositions, however, they usually tend to have more SiO2 than peridotites.
What is Quartz is rich in which element?
Quartz consists of silicon and oxygen (2 times as many oxygen atoms than silicon atoms).
Which a halite crystal differs from a quartz crystal?
1) The covalent bonds in quartz are much stronger than the ionic bonds in halite. 2) The stronger bonds of quartz make it harder than halite. 3) You can easily scratch halite with a steel knife ,while you cannot scratch quartz.
Does oil pour faster than water?
No, oil does not pour faster than water
Why do you use quartz cuvette rather than using glass cuvettes?
Glass will absorb radiation below 320nm whereas quartz will allow transmission of the UV wavelengths. So use glass cuvettes for wavelengths in the visible range from 380nm to 780nm and quartz cuvettes for wavelengths below 380nm.
Which would weather faster olivine or quartz?
Olivine would weather faster than quartz
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 it doesnt
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
What specific solid does sound travel through the fastest?
The denser the faster. ie: it will travel faster through quartz than sandstone.
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.
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.
How much gabbro is in olivine?
Olivine does not contain Gabbro. Gabbro can contain olivine. Usually no more than a few percent.

How would you describe the composition of igneous rock?
There are many sorts of igneous rocks. Granite is made of quarts, feldspar, and mica, while basalts are made of less than 20% quartz and less than 10% feldspar and the rest made up of pyroxenes and olivine.
What minerals make up a rhyolite rock?
The mineral assemblage of Rhyolite is usually quartz, alkali feldspar and plagioclase (in a ratio > 1:2) and biotiteand hornblende are common accessory minerals. More importantly quartz has got to comprise more than 69% of the rock.
What is faster the speed of light or speed of sunlight?
That's like asking whether a car is faster than a Ford, or whether an animalcan outrun a horse.Sunlight is light, and it travels at the speed of that which it is.
