Granite doesn’t result from volcanic eruptions and is rarely found on the surface like extrusive rocks. The primary difference between a granite and a gabbro is the silica content (gabbro has less silica than granite). Absolute Black Granite is a very dark black, fine to close-grained black basalt (dolerite) of the Precambrian period with equi-granular crystalline texture. In contrast, gabbro weathering-rind systems are characterized by many thin (< 1 cm) rindlets whose alteration products are dominated by limonitization of ferromagnesian minerals. Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. Diorite is an intrusive igneous rock composed principally of the silicate minerals plagioclase feldspar (typically andesine), biotite, hornblende, and/or pyroxene. Engineered Quartz for Your Kitchen Countertop. Gabbro (/ ˈ ɡ æ b r oʊ /) is a phaneritic (coarse-grained), mafic intrusive igneous rock formed from the slow cooling of magnesium-rich and iron-rich magma into a holocrystalline mass deep beneath the Earth's surface. They have very different textures because they form differently (slow cooling vs fast cooling). Therefore, more basalt than gabbro, and more granite than rhyolite. Appearance of Granite is Veined or Pebbled and that of Gabbro is Veined and Shiny. Most pegmatites have a composition that is similar to granite (granite pegmatites) with abundant quartz, feldspar, and mica.
