What size are the crystals on diorite?
Diorite, being an intrusive igneous rock, formed underground by slow cooling, would have crystals large enough to be visible.
Does granite have anything to do with diorite?
Both are intrusive igneous rocks. Diorite is sometimes found in association with granite.
Compare the mineral composition of diorite with the mineral composition of andesite?
Both andesite and diorite are igneous rocks with an intermediate color index. Diorite; however, is intrusive and phaneritic, whereas andesite is aphanitic and extrusive. Andesite is said to be the extrusive equivalent of diorite. Diorite is made up of plagioclase feldspar and ferromagnesian mineral crystals, mainly amphibole. Contrarily, andesite may resemble rhyolite, meaning it presents a need for microscopic examination to see its mineral crystals. The two have a composition of plagioclase feldspar and amphibole, but it is much more difficult to detect in andesite.
Where are crystals found?
In rocks, mines....practically everywhere. Crystals are found all around the world. One place is in caves where they can be quite large. Geodes contain crystals and there are many types/colors of crystals. One of the most common is quartz that is often white, but there is also smoky quartz, and rose quartz. Many gem stones are a form of crystals.
Do igneous rocks have small crystals large crystals or no crystals?
It depends on the type of igneous rock. Intrusive igneous rocks such as granite have large crystals, extrusive igneous rocks may have small crystals as in basalt or no crystals as in pumice.

Diorite, being an intrusive igneous rock, formed underground by slow cooling, would have crystals large enough to be visible.
Are there crystals on diorite?
YEAH
What is an example of an intrusive igneous rock with large crystals?
Porphyrite of any composition, granite, gabbro, diorite. Most intrusive igneous rocks have crystals large enough to see with the naked eye. Another term used to define an igneous rock with large crystals is coarse-grained.
What are large mineral crystals commonly found in?
large mineral crystals are most likely found or have grown in igneous or metamorphic rocks

How can you tell that diorite rock is an intrusive igneous rock?
because most intrusive igneous rock are found underground and diorite is found under the earth.
Where is diorite lava quartz and limestone found?
in Mexico
What is a type of igneous rock that forms visible crystals?
Granite, gabbro, and diorite are a few igneous rocks that forms crystals. Igneous rocks that form visible crystals are intrusive igneous rocks, rocks that form under the earth's surface.
How do the igneous rocks granite and diorite form?
They form in essentially the same way, the only real difference being in composition. They form as magma slowly cools deep underground, allowing large crystals to form. Granite forms from magma that is rich in silica, sodium, and potassium. Diorite forms from magma that has somewhat less silica and more iron, calcium, and magnesium.
Can large crystals be found in rocks?
Yes, rocks can contain a variety of crystal sizes.
Where is lava quartz diorite and limestone found in the same location?
Aruba
