Granite does not belong to any crystal structure group because granite is a rock, not a mineral, and only minerals can be grouped by crystal form or shape. Minerals are naturally occurring solids which form the earth and make up its rocks. Minerals develop in predictable geometric patterns called crystals. The term used to describe a crystal's general shape is habit. Some examples of crystal habit groups are cubic, prismatic, tabular, etc. Minerals are sometimes called the building blocks of rocks because rocks are usually made up of 2 or more minerals which formed together in the same space, often without enough room for recognizable crystal formation. The minerals involved and the environment they formed in will determine the type of rock they make. Granite is a rock formed underground from cooled magma (lava that never reached the earth's surface) containing the minerals quartz, feldspar, mica and others. Each individual mineral in a rock belongs to a particular crystal group, but not the rock itself.

What is an fact about Granite?

Granite is very resistant to fracture because of its interlocking mineral crystal structure.


Is granite crystal or grain size?

How is Granite different from Sandstone?

Granite is composed of interlocking grains, a result of minerals solidifying at different temperatures as they cool from magma. This interlocking structure makes granite very durable and hard. Sandstone is formed of cemented sand sized grains. The bond between grains is not as strong as the interlocking grain found in granite.

Will sulfuric acid dissolve granite rock?

Yes, sulfuric acid will attack granite. We're only going to approach this from a general perspective, but we can answer the question. Granite is what is called a felsic mineral, and much of it is composed of compounds that are individually composed of a metal plus silicon plus oxygen. The acid will, in general, target the metal, and will combine with it. This will tear it away and out of the crystal structure of the rock, and it will effectively destroy the structure of the granite.

Why is a crystal of salt classified as a pure substance and a slab of granite classified as an impure substance?

Salt is a single compound, but granite contains different compounds. Salt has a single crystal, but a slab of granite contains more than one crystal. Salt contains different compounds, but granite contains different elements. Salt can be dissolved in water, but granite can not be dissolved.


Is granite hard?

Feldspar and quartz, with a hardness of 6 and 7 on the Mohs Scale respectively, are the minerals that give granite its abrasion resistance. Its hardness is due to the interlocking crystal structure as it cools from melt, making it among the hardest of rock types.
