Is gabbro as good as granite.

Gabbro is a dark medium to coarse grained intrusive igneous rock composed of calcium plagioclase pyroxene and minor olivine but no quartz.

Gabbro vs granite compare nature. It means that it formed as magma cooled slowly in the crust.

Gabbro any of several medium or coarse grained rocks that consist primarily of plagioclase feldspar and pyroxene essentially gabbro is the intrusive plutonic equivalent of basalt but whereas basalt is often remarkably homogeneous in mineralogy and composition gabbros are exceedingly variable gabbros are found widely on the earth and on the moon as well. Gabbro in continental crust on the continents gabbro can be found within thick lava flows of basaltic composition where slow cooling allows large crystals to form. It is frequently used for countertop and flooring materials gravestones and exterior and. Polished gabbro is sold under the name black granite and is used for cemetery markers floor tile kitchen counter tops facing stone and other dimension stone uses.
