A pegmatite is an intrusive igneous rock comprised of coarse, interlocking mineral grains usually above three centimeters in diameter. Although very many pegmatites are granitic in composition, several hundred mineral species have been found in the most famous pegmatites worldwide, including many rare and valuable minerals. A few discovered pegmatite crystals have grown to several meters across.

Why do your new jeans have a furry texture to it?
It depends on the material they are made from. Some jeans are made from brushed cotton, and this texture would be normal.
Why are figs so gross?
They tend to have a horrible texture.
What color and texture is the skin of the Kiwi?
The skin of a kiwi is typically brown and has a fuzzy texture, covered in short, hair-like fibers. The color can vary slightly, with some kiwis being more yellowish-brown. The texture contributes to its distinctive appearance and is usually not eaten, as the flesh inside is bright green or golden and smooth.
What is the appearance and texture of the diaphragm of a pig?
The diaphragm of a pig appears as a thin, dome-shaped muscle that separates the thoracic and abdominal cavities. It has a smooth and shiny appearance with a rubbery texture.
What texture does horse hair have?
it is rather coarse no matter how much you wash it. it is just how horses are made.
What is pegmatite texture?
Pegmatite texture is a coarse-grained igneous rock texture characterized by exceptionally large crystals. These crystals can be several centimeters to several meters in size. The slow cooling of molten rock in pegmatite formations allows for the growth of such large crystals.
Which characteristic provides the best evidence that pegmatite is solidified deep underground?
Very coarse texture.
What kinds of fossils are in pegmatite?
Pegmatite is typically an igneous rock characterized by its coarse-grained texture and is not commonly associated with fossils, as it forms from the crystallization of magma. However, in some cases, pegmatite can contain minerals that may preserve organic material or trace fossils, such as stromatolites, especially if the pegmatite intrudes sedimentary layers. These organic remains are rare and typically not well-preserved, but they can provide insights into ancient biological activity. Overall, pegmatite is primarily valued for its mineral content rather than fossil preservation.
Which characteristic provides the best evidence that his pegmatite solidified deep underground?
Large crystal size is the best evidence that a pegmatite solidified deep underground. This is because slow cooling at depth allows sufficient time for minerals to grow into large crystals before solidification.
Where can you find a pegmatite rock?
There is no such thing as a "pegmatite rock" in the Pokemon D/P games.
What Pegmatite used for?
Pegmatite is used for feldspar, sheet mica, beryllium, tantalum niobium, and lithium minerals.
Where can you find pegmatite?
in the core
What shape is an pegmatite?
it has a round shape
What kind of rock is pegmatite is it sedimentary igneous or metamorphic?
Pegmatite is an igneous rock that forms in the final stage of magma crystallization. It typically contains large crystals due to the slow cooling of the magma.
Why is pegmatite igneous?
Pegmatite is classified as an igneous rock because it forms from the cooling and solidification of molten material, typically within the Earth's crust. Pegmatite is characterized by its large crystal size, which indicates that it cooled slowly, allowing the minerals to grow to a significant size.
What is the hardness of pegmatite?
The hardness of pegmatite can vary depending on its mineral composition, but it typically falls between 6 to 7 on the Mohs scale of mineral hardness. This means that pegmatite is harder than steel but softer than quartz.
How are the ways in which pluton and pegmatite minerals from similar?
yes
