What Is The Main Difference Between Granite And Rhyolite

So i m going to make a general comment and say that a granite is genetically the same has the same composition as a rhyolite please don t take this as always true but it is a close enough estimate in most cases.

What is the main difference between granite and rhyolite. Volcanic in origin it makes up much of the earth s oceanic crust. The key difference between basalt and granite is that basalt is mostly occurring on ocean floors while granite is in the crust of the earth in all continents. What is the difference between gneiss and granite. Match each igneous rock with its correct texture.

Appearance of granite is veined or pebbled and that of rhyolite is banded. Properties of rock is another aspect for granite vs rhyolite. Granite is an igneous rock whereas gneiss is formed after metamorphosis of an existing igneous rock. Both granite and rhyolite are felsic igneous rocks with roughly the same amount of silica.

Both rhyolite and basalt are types of igneous rocks igneous rocks are usually found in two forms as intrusive and extrusive igneous rocks based on the method of formation. Gabbro is a dark medium to coarse grained intrusive igneous rock composed of calcium plagioclase pyroxene and minor olivine but no quartz. A plutonic igneous rock is one that crystallises. Hardness of granite and rhyolite is 6 7.

Granite is available in black grey orange pink white colors whereas rhyolite is available in grey white light black colors. All rocks of igneous origin consist of magma or molten earth that finds its way up to. As nouns the difference between granite and rhyolite is that granite is rock a group of igneous and plutonic rocks composed primarily of feldspar and quartz usually contains one or more dark minerals which may be mica pyroxene or amphibole granite is quarried for building stone road gravel decorative stone and tombstones common colors are gray white pink and yellow brown while. Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks.

The main difference between the two is granite forms beneath the surface where it has sufficient amount. As nouns the difference between rhyolite and basalt is that rhyolite is geology an igneous volcanic extrusive rock of felsic composition with aphanitic to porphyritic texture while basalt is mineral a hard mafic igneous rock of varied mineral content. So if we assume the above to be true then the only difference between the rocks is that one is plutonic and the other is volcanic. The mineral composition of both granite and gneiss is same but alteration of granite because of very high pressure and temperature leads to the formation of gneiss.
