Is Granite And Basalt A Sedimentary Rock

Summary of basalt vs.

Is granite and basalt a sedimentary rock.

Basalt is an extrusive and mafic igneous rock. It is common both on earth and other planetary bodies. 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.

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. The main minerals present in granite rocks are quartz feldspar and mica. 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.

These rocks are the major continental rocks. It commonly comprises the bulk of ocean islands and the oceanic crust. Granite rocks form due to the slow cooling of pockets of magma deep below the earth s surface. All rocks of igneous origin consist of magma or molten earth that finds its way up to.

A few examples for types of igneous rocks are granite scoria or basalt pumice and obsidian. Basaltic lava flow idaho basalt is the stuff of the ocean floor. 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.
