What mineral tends to form last in Bowen's series?
Quartz.
Is a Tourmaline quartz the same as Tourmaline gemstone?
Tourmaline often occurs in long thin needles densely included inside Quartz. Such material is known as Tourmalinated Quartz. Tourmalinated quartz is carved into valuable ornamental objects and figures.
How does a smoky quartz crystal form?
Smoky quarts is a greyish-brownish type of quarts that occurs naturally in some parts of the world. Some sources of smoky quartz are in Brazil, Mozambique, Madagascar, Australia, Scotland, Switzerland, and in New Hampshire and Colorado in the United States.
Last mineral to crystalize cooling magma?
The most common igneous rock forming minerals (i.e. those which crystallize from magma) include:QuartzPotassium FeldsparPlagioclase Feldspars (ranging from sodium to calcium rich, known as Albite and Anorthite respectively).BiotiteHornblendePyroxeneOlivinePlease see the related link.
What is the volume of quartz?

How long does a quartz battery last in a wristwatch?
watch batteries last for 1-2 years, check the manual
How does smoky quartz crystal form?
Smoky quartz is normally found in granite mountains. Smoky quartz is regular quartz which is exposed to radiation on a long term basis.
What mineral crystallizes last and is most resistant to weathering?
Quartz
What mineral tends to form last in Bowen's series?
Quartz.
Which mineral is last to crystallize?
In solidifying igneous rock, usually quartz.

Is quartz a silicate mineral?
Quartz is not a salt; it is silicon dioxide, SiO2.
What is the mineral classification of quartz?
The group of rocks that usually have the mineral quartz as part of their composition is the granitic group. Quartz is one of the last minerals to crystallize filling in the gaps in granite as it cools.
How long does it take for a quartz crystal to grow one millimeter?
A small quartz crystal can grow about 1mm a week assuming it is in a stable matrix.
Why is quartz shapeless?
"Shapeless" quartz is usually associated with tectonic movements and metamorphic rocks. In granites it is about the last mineral to crystallise and it fills the spaces between the micas and feldspars. In a crystalline form it forms long hexagonal (six sided) usually clear transparent crystals which are topped off with a hexagonal pyramid
How long does piezo material last?
Great question: A piezoelectric material such as quartz might a very long time, but they do age. But for applications where absolute frequency stability is needed, other methods are used. See: http://en.wikipedia.org/wiki/Crystal_oscillator
How was quartz formed?
it was formed from extreme pressure for a long time under the earth.
