They are associated with the late stages of granite intrusions and the minerals formed in pegmatites literally had the time to enjoy the benefits of a slow crystallization process from a rich chemical stew produced by the cooling granite.

Can you find any crystals or diamonds in California?
Crystals of many different minerals can be found in California. California's most famous mineral would perhaps be tourmaline, found in huge pink crystals at the Himalaya Mine. Diamonds are commonly found in the placer gold mines of California, but are generally quite small.
How is hornblende made?
Hornblende is a common mineral found in igneous and metamorphic rocks. The crystals form from the consolidation of elements found in the magma or parent rock.
Are large crystals found in diorite?
diorite crystals are large and andesite crystals are small
The size of the mineral crystals found in an igneous rock is directly related to the?
the rate melted rock cools.
Do rocks have crystals?
Some rocks may contain crystals, but not all rocks contain crystals. Crystals can be found in rocks that have volcanic origin.
Is beryl a mineral or rock?
Beryl can be found in alluvial deposits from erosion out of pegmatite veins. This is the easy way, sorting through sand and gravel. The hard way is to attack the granitic pegmatite with tools and see what's inside.
What is a pegmatite texture?
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.
What are large mineral crystals commonly found in?
large mineral crystals are most likely found or have grown in igneous or metamorphic rocks
Where is the mineral orthoclase found?
The mineral orthoclase is found all over the world. It can also be found in Granite rock. It would be the pink or white crystals in it.
What kind of faces are found in mineral crystals?
Mineral crystal faces of varying luster and geometric shapes.
Where and what was the largest crystal found?
Quartz crystals have been found that are over 30 meters in length. For a list of the world's largest mineral crystals, click on the link below.
What is an element or inorganic compound that is found in nature as solid crystals?
inorganic chemistry
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.
Which thing is Beryl found in?
beryl is usually found in pegmatite of different kinds.
What kind of crystals are found in clay?
Gypsum crystals are the most common type of crystal mineral found in clay. Gypsum Crystal are known for their flexibility and is commonly used for wallboards or plaster products.
What are the uses for atacamite?
Atacamite can be an ore of copper. It can be found as flashy green crystals that are popular among mineral collectors.
What is adularia?
Adularia is a form of orthoclase feldspar, a mineral which forms igneous rock, found in white prismatic crystals.
