Granite Rock

Granite''s main minerals are quartz, feldspar and mica, however with so many different variations, the whole mineral composition of course varies. If the magma with the same composition forms an extrusive igneous rock, it will be rhyolite .

The Density of Common Rocks and Minerals

 · Rock density is very sensitive to the minerals that compose a particular rock type. Sedimentary rocks (and granite), which are rich in quartz and feldspar, tend to be less dense than volcanic rocks. And if you know your igneous petrology, you will see that the more mafic (rich in magnesium and iron) a rock is, the greater its density.

Rocks and minerals

For example granite is an igneous rock mostly made from different proportions of the minerals quartz, feldspar and mica, as interlocked crystals. A sandstone is a sedimentary rock that can also contain quartz, feldspar and mica minerals, but as grains compacted and cemented into each other.

Granite Rocks : What Is Granite Rock And How Is It …

 · The term "granite" is used for granite and a group of intrusive igneous rocks with similar textures and slight variations in composition and origin. These rocks consist mainly of feldspar, quartz, mica, and amphibole minerals, forming an interlocking, somewhat equigranular feldspar and quartz matrix with dispersed darker biotite mica and amphibole (often hornblende) peppering the lighter …

On Vancouver beaches, granite (an igneous rock made up of different minerals) is often in the form granodiorite (black granite), which is speckled black, white, and grey/pink. Other common Vancouver beach rocks: smooth black rocks are likely to be basalt (igneous rock, cooled lava), and flat rough light brown rocks are likely to be sandstone (sedimentary rock made up of different minerals).

Granite

Granite is a light-colored plutonic rock found throughout the continental crust, most commonly in mountainous areas. It consists of coarse grains of quartz (10-50%), potassium feldspar, and sodium feldspar. These minerals make up more than 80% of the rock.
