Is Granite And Basalt A Sedimentary Rock

It forms from lava flows which extrude onto the surface and cool.

Is granite and basalt a sedimentary rock.

The main minerals present in granite rocks are quartz feldspar and mica. Summary of basalt vs. These rocks are the major continental rocks. But granitic basement rock can be found just about everywhere east of the rockies if you re willing to dig through the dirt and sedimentary rocks at the surface.

It is common both on earth and other planetary bodies. A few examples for types of igneous rocks are granite scoria or basalt pumice and obsidian. Basalt occurring on continents is often associated with rifting and forms part of a large igneous province and or flood basalt. Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks.

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. All rocks of igneous origin consist of magma or molten earth that finds its way up to. Its principle minerals include pyroxene feldspar and olivine. Granite rocks form due to the slow cooling of pockets of magma deep below the earth s surface.

Granite is intrusive which means that the magma was trapped deep in the crust and probably took a very long time to cool down enough to crystallize into solid rock. Basalt is an igneous volcanic rock that forms commonly in oceanic crust and parts of continental crust. It commonly comprises the bulk of ocean islands and the oceanic crust.
