WebGabbro is an intrusive igneous rock composed primarily of plagioclase feldspar and large amounts of mafic minerals like pyroxene. It has a phaneritic texture, meaning its interlocking crystals can be seen with the naked eye. It is usually dark gray, black, or dark greenish, and is closely related to basalt. thinkcar thinkscan 600WebGabbro and norite are basic intrusive rocks composed principally of calcic plagioclase and pyroxene, with or without olivine. In gabbro the dominant ferromagnesian mineral is clinopyroxene, whereas it is orthopyroxene in norite. The expression “gabbroic rocks” includes both gabbro and norite. thinkcar thinkscan 660WebFelsic intrusive igneous rocks (e.g., granite) are usually light in color because they are rich in minerals like feldspar that contain a lot of Al, Na, or K. Mafic intrusive igneous rocks (e.g., gabbro and peridotite) are darker in color, again reflecting the compositions of the minerals present, which tend to be rich in Mg and Fe. thinkcar thinkscan 600 obd2 scannerWebGabbro is an igneous rock, is coarse-grained, dark-colored and intrusive.
