Granite Vs Gabbro: Similarities and Differences, Definition, Texture, Classification, Mineralogy, Occurrence, Uses. Biotite and perthitic microcline were separated from a fresh granite and its attendant weathering-rind system. In contrast, gabbro weathering-rind systems are characterized by many thin (< 1 cm) rindlets whose alteration products are dominated by limonitization of ferromagnesian minerals. The streak of Granite is white while that of Gabbro is black. Granite and rhyolite are considered felsic, while basalt and gabbro are mafic (click here for more information on mafic and felsic).

Also, gabbro has no alkali feldspar, only plagioclase feldspar with a high calcium content. It’s easy to confuse Granite with other types of intrusive rocks like gabbro, but it is very easy to differentiate it from extrusive rocks like basalt. - AND not all granites, basalts, and gabbros contain exactly the same minerals. Igneous rocks with similar composition are basalt (extrusive equivalent of gabbro) and diabase (the same rock type could be named dolerite or microgabbro instead).. Gabbro with large augite phenocrysts embedded in white plagioclase. Stone Selection: Granite Slabs: All. The granite–syenite–gabbro association was emplaced in two major episodes.
