Difference Between Granite And Rhyolite

One is intrusive and the other is extrusive.

So I'yard going to make a general comment and say that a granite is genetically the same (has the aforementioned composition) as a rhyolite. Delight don't take this as ever truthful but it is a close enough judge in most cases.

And so if we assume the above to exist truthful then the simply difference between the rocks is that one is plutonic and the other is volcanic.

A plutonic igneous rock is ane that crystallises deep in the crust (can be 10s of kilometres deep). They are characterised by large crystals which we term coarse-grained. Some other term for this type of rock is an intrusive stone. A granite is this.

The other blazon is chosen an extrusive igneous rock and is one that breaks through to the surface to crystallise on or near the Globe's surface resulting in a fine-grained rock. A rhyolite is this and is usually erupted onto Earth'south surface.

So if we look at the Quartz-Alkali-Plagioclase (QAP) ternary diagram you can see that granite and rhyolite sit in similar positions. The difference is that granite sits on the plutonic diagram and rhyolite sits on the volcanic diagram. Then they accept a similar limerick but ane is volcanic and the other is plutonic.

Summary:

  1. Granite is plutonic and rhyolite is volcanic.
  2. They have very like compositions but one is erupted onto Earth's surface and the other crystallises at depth.
  3. As a event, plutonic rocks are coarse-grained and volcanic rocks are fine-grained.
