Slow cooling of diorite results into coarse grain size due to large crystals formation with more ion transport.
What is the grain size of granite in.
Grain size determines just how far a piece of sediment can travel before coming to a halt.
Since granite are generally thought to be coarse grained does that mean the grain size of granite at egs conditions is between 5 mm to 3 cm.
Igneous rocks are made up of several different mineral crystals that grow within the melt as it cools.
49 that is a lower yield strength material will typically have a larger grain size.
The pink grains are orthoclase feldspar and the clear to smoky grains are quartz or muscovite.

One objection to the earth being only 6 000 years old as described in the bible is the claim that the coarse grained texture of granites shows they cooled slowly over millions of years.
The specimen above is a typical granite.
Clastic sediments form a wide range of rocks from mudstone to conglomerate and soil depending on their grain size.
The black grains can be biotite or hornblende.
You can change the grain size of a metal by heating it up to its melting point and then allowing it to cool again.
The grain size is coarse enough to allow recognition of the major minerals.
It is about two inches across.
The video below is a clip of crystals forming in solution.
Crystals in magma grow in a similar way as the melt cools.
As magma cools it begins to crystallise and form solid rock.
Granites can be predominantly white pink or gray in color depending on their mineralogy the word granite comes from the latin granum a grain in reference to the coarse grained structure of such a completely crystalline rock.

Numerous other minerals can be present in granite.
The difference is grain size and cooling rate during the rock formation process.
Within many of these rocks the sediments are clearly distinguishable especially with a little help from a magnifier.
Rapid cooling of andesite which is forming closer to the surface results in fine grained textured rocks.
