Basalt is mafic while granite is felsic. Gabbro is coarse-grained while basalt is fine-grained. Granite and Gabbro cooled slowly beneath the surface of the earth in igneous intrusions plutons 1 consequently allowing time for the formation of large macroscopic mineral crystals 1.

Moreover gabbro is an intrusive rock while basalt is an extrusive rock. State the name of rock B. Mount Rushmore was sculpted between 1927 and 1941 out of an outcrop of granite near Keystone South Dakota.

Basalt is a dense dark fine grained igneous rock of a lava flow or minor intrusion composed of labradorite and pyroxene. Samples 30 61 291 Granodiorite is an igneous rock intermediate between granite and diorite in composition and can form directly by partial melting or by mixing of different. Minerals in these specimens refer to chart at end of handout.

While gabbro is usually green in colour basalt is grey to black. Basalt is volcanic or extrusive forming at the surface while granite is plutonic or intrusive forming beneath the surface. Granite is a hard igneous rock that is mostly made up of feldspar and quartz.

Gabbro is deep beneath the Earths surface while basalt is at or near the surface of the Earth. Although both granite and granodiorite are very rich in quartz granite tends to have less magnesium and iron and other dark minerals while granodiorite has more calcium and sodium and therefore more dark minerals. As against Granite is a coarse-grained igneous rock composed of orthoclase and albite feldspars and quartz.

The differences between Granite and Rhyolite and Gabbro and Basalt relate to differences in the rate and environment of cooling. Granite is a coarse-grained igneous rock with average grain size ranging from 1 to 25 millimeters. The difference is that granite sits on the plutonic diagram and rhyolite sits on the volcanic diagram.
