Is Granite And Basalt A Sedimentary Rock

It commonly comprises the bulk of ocean islands and the oceanic crust.

Is granite and basalt a sedimentary rock.

Basalt is an extrusive and mafic igneous rock. The main minerals present in granite rocks are quartz feldspar and mica. Basalt occurring on continents is often associated with rifting and forms part of a large igneous province and or flood basalt. Granite and basalt are opposites on these axies for the description of igneous rocks granite is a slow cooled quartz rich rock basalt a rapidly cooled mafic rock.

Basaltic lava flow idaho basalt is the stuff of the ocean floor. Summary of basalt vs. Basalt is an igneous volcanic rock that forms commonly in oceanic crust and parts of continental crust. 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. 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. It is common both on earth and other planetary bodies. It forms from lava flows which extrude onto the surface and cool.

A few examples for types of igneous rocks are granite scoria or basalt pumice and obsidian. 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. All rocks of igneous origin consist of magma or molten earth that finds its way up to.
