Granite is composed of numbers of individual mineral crystals and these crystals of individual minerals can be referred to as grains. Due to the formative processes involving granite, individual mineral crystals may not have what is popularly thought of as a crystal form, although they truly are mineral crystals. Grains could also be crystals or particles of other rocks which make up some sedimentary rocks. The grain size is part of the determination of the rock's texture: fine-grained, coarse grained, etc..

∙ 13y agoNo. Granite is composed mainly from the minerals potassium and plagioclase feldspar, along with quartz, and varying amounts of biotite and muscovite mica with some hornblende.
However the weathering of feldspar minerals in granite can form clays and the quartz from a weathered granite may ultimately form sand.

What type of grains is metamorphic made from?
crystals
Which has smaller crystals basalt or granite?
i think that basalt is the smaller crystals out of the two, as the crystals in granite are larger.
What are mineral grains made up of?
Mineral grains are crystals or pieces of crystals that vary widely in chemical composition. There are over 4,000 different minerals that have been identified so far.
What is C is the name used to describe grains that fit together?
Crystals
Why do some igneous rocks have big crystals or grains and some igneous rocks have small crystals or grains?
how long they stayed in the volcano; how much time the crystals had to form
Granite have small or large grains?
Large grains, and crystals
Is granite made from interlocking crystals?
not sure but i know it's an example of interlocking grains.. Interlocking visible crystals would be good descriptive words for granite.
Does granite have grains sometimes called crystals?
no
Does granite have Gaps between the Grains?
No. Granite does not have gaps between the grains. The crystals in an intrusive igneous rock are interlocking.
How is granite different to sandstone?
Granite is an Igneous rock, sandstone is a sedimentary rock, sandstone is made up of grains that are bonded together lightly, you can even rub some of the grains off with your hands. Granite is not made from grains, they are deep into the mountains, and used for building materials, they even have crystals in them.
Does granite have large mineral grains?
Granite is formed from magma that cools slowly, deep below the earth's surface. Very coarse-grained granite, called pegmatite, is formed when the magma cools extremely slowly. Most granite is hard grained
What is a hard rock made of crystals-not permeable?
granite is a hard rockk madeof crystals
What type of grains is metamorphic made from?
crystals
What is a rock's texture?
The texture of a rock consists of it's grain or mineral crystal size, the arrangement of the grains or crystals, and the degree of uniformity of the grains or crystals. Examples of rock texture would be: * Coarse grained--visible crystals or grains as in granite. * Fine grained--small grains, invisible to the unaided eye as in shale. * Porphyritic--large visible crystals in a fine grained matrix as in granite porphyry. * Schistose--layers of flattened micaceous minerals such as in mica schist. * Foliated--a metamorphic rock texture of parallel mineral banding as in gneiss. * Homogenous--same grain apperance in all directions as in basalt.
Which has smaller crystals basalt or granite?
i think that basalt is the smaller crystals out of the two, as the crystals in granite are larger.
Why do they call granite granite?
Granite is actually made of mineral grains that are stuck together and solidified. It appears that the name "granite" comes from the based word "grain".
Does granite have rounded grains?
Granite does not have rounded grains but contains interlocking grains. An example of a rock with rounded grains is a sandstone.
