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 do fish-ball contain starch?
Starch is commonly added to fish balls as a binder to help the mixture hold its shape and texture during cooking. It also helps to improve the overall consistency and enhances the chewy texture of the fish balls.
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.
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
What is the chemical composition of pegmatite?
Pegmatite is a light-colored, extremely coarse-grained intrusive igneous rock. It forms near the margins of a magma chamber during the final phases of magma chamber crystallization. It often contains rare minerals that are not found in other parts of the magma chamber.
