What is the luster of gabbro?
As a rock, gabbro does not have a luster. Luster is a term used to characterize a mineral.
Does gabbro have crystals?
Yes. Gabbro is an intrusive igneous rock with visible mineral crystals.
Can gabbro contain mineral quartz?
No, gabbro does not typically contain mineral quartz. Gabbro is a coarse-grained igneous rock composed primarily of calcium-rich plagioclase feldspar and pyroxene minerals. Quartz is not a common mineral in gabbro; it is more common in granitic rocks.
How does a basalt differ from gabbro?
Gabbro has much larger grains that basalt does. This is because basalt cools faster than gabbro and has less time to form crystals.
What type of rock is gabbro?
Gabbro is a type of rock that is dense and dark in color. It is made up of parts of oceanic crust, which is highly compressed.
What makes gabbro a rock and not a mineral?
Gabbro is usually made up of minerals such as pyroxene, plagioclase, amphibole and olivine which makes it an intrusive igneous rock.
Which mineral is present in much greater quantities in peridotite than in gabbro?
The answer is peridotite.
Which mineral is present in much greater quanitites in peridotite than in gabbro?
olivine
Which mineral is present in much greater quantities in peridotite than gabbro?
Olivine
What rock is similar to basalt in mineral make up is intrusive and has coarse grains?
It is Gabbro
Does Gabbro and granite have a similar mineral composition and texture?
the textures are similar yes but gabbro is made up of calcite and olivine while granite contains biotite mica, feldspar, and quartz.
Dark course grain intrusive igneous rock simliar to basalt and mineral make up?
Gabbro.
