A pegmatite is a rock formed under certain favorable circumstances that enhance the crystal size of the rock. The crystals would be larger than those in basalt, an extrusive igneous rock, and granite, and intrusive igneous rock.

What is an igneous rock with crystals?

Granite with larger crystals, basalt with smaller crystals.


What are the difference between the sizes of the particles in granite with those in basaalt?

The crystals in granite, being intrusive in nature, will be larger than those in basalt, an extrusive igneous rock. Intrusive igneous rocks have cooled slowly from magma, extrusive rocks have cooled quickly from magma. Crystals grow larger from slow cooling magma.


Why does Granite take much longer to form than Basalt?

hmmm, granite is intrusive, formed and cooled slowly at depth with larger individual crystals. Basalt is extrusive, fine grained (small crystals and cooled quickly. The intrusive equivalent of basalt is gabbro. For granite; rhylolite


What type of rock has crystals embedded within it?

Igneous rocks, such as granite and basalt, often have crystals embedded within them.


How will the size of crystals in granite be different to the size of crystals in basalt?

because they take longer to cool from the magma it is formed from


What type of rock has crystals inside?

Igneous rocks, such as granite and basalt, often have crystals inside due to their formation from cooling magma.


Is igneous rock granite or basalt?

Both granite ans basalt are types of igneous rock.


Which rock has more silica granite or basalt?

Granite has more silica than basalt in it.


How do you differentiate granite from basalt?

Although they are both igneous rocks which have solidified from magma, granite is an intrusive igneous rock and basalt is an extrusive igneous rock. As an extrusive igneous rock, the magma that formed granite had a long time to cool underground, and therefore consists of larger, visible mineral crystals. Basalt on the other hand, cooled rather rapidly from magma after eruption from a volcano and therefore is aphanitic, with crystals too small to be seen with the naked eye. There is also a difference in chemistry. Granite is considered felsic, with a preponderance of silicate minerals like quartz and orthoclase feldspar. Basalt is considered mafic, with an abundance of heavier minerals like olivine and amphibole, thus making it heavier than granite. These minerals also give basalt a dark color compared to the lighter colored granite.


How does Basalt differ from granite?

Basalt is an extrusive, mafic igneous rock, which means that it solidifies from lava at or near the surface, and is composed partly of iron and magnesium minerals. Granite is an intrusive felsic igneous rock, meaning that it solidifies from magma below the surface, and is relatively high in minerals containing silicon and aluminum. Basalt has a higher specific gravity than granite, and is also darker than granite. Basalt may have visible air pockets, frozen in place when it solidified from lava. Granite will not exhibit this characteristic. Basalt has mineral crystals that are not visible with the naked eye. Granite has visible mineral crystals.


Which type of rock contains minerals arranged in crystals and forms when molten rock cools and turns solid?

Igneous rock contains minerals arranged in crystals and forms when molten rock cools and solidifies. Examples include granite and basalt.


Why would granite rock have larger crystals than igneous rocks formed from lava cooled above the earth's surface?

Because crystals in granite had more time to form
