Basalt is an extrusive and mafic igneous rock. 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. 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. Summary of basalt vs.

It commonly comprises the bulk of ocean islands and the oceanic crust. The main minerals present in granite rocks are quartz feldspar and mica. A few examples for types of igneous rocks are granite scoria or basalt pumice and obsidian. Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks.

Granite rocks form due to the slow cooling of pockets of magma deep below the earth s surface. Basaltic lava flow idaho basalt is the stuff of the ocean floor. It is common both on earth and other planetary bodies. Basalt is an igneous volcanic rock that forms commonly in oceanic crust and parts of continental crust.

Its principle minerals include pyroxene feldspar and olivine. Basalt occurring on continents is often associated with rifting and forms part of a large igneous province and or flood basalt. These rocks are the major continental rocks.
