Which igneous rock has a dark color?
Mafic
What is the dark colored igneous rock with rich in iron and magnesium?
The dark-colored igneous rock rich in iron and magnesium is called basalt. Basalt is a fine-grained rock that is commonly found in volcanic areas and oceanic crust. It is characterized by its dark color due to the presence of minerals like pyroxene and olivine.
Basaltic magma forms what kind of igneous rock?
Mafic igneous rock. ( due to Ferromagnesian minerals).
Is basalt metamorphic?
Yes. Basalt is an extrusive mafic igneous rock.
classificatio of igneous rock?
felsic, intermediate, mafic, and ultramafic.
What is the igneous rock between granite and basalt?
Andesite is considered an intermediate rock between granite (felsic igneous rock) and basalt (mafic igneous rock), based on chemical composition.
How An igneous rock that contains mostly Pyrexes and Olive has?
The igneous rock with mostly pyroxenes and olivine is likely a mafic rock, such as basalt or gabbro. These minerals are common in mafic rocks due to their high iron and magnesium content. Mafic rocks are associated with oceanic crust and volcanic activity.
Which of the igneous rock types has the lowest silica content?
Ultramafic igneous rock contains the least silica.
Are all rocks either mafic or felsic?
No. First of all, the terms mafic and felsic generally only apply to igneous rock. even among igneous rocks, mafic and felsic are just ranges on a "spectrum" of composition. Other classifications and examples include ultramafic (peridotite), intermediate (andesite), and intermediate-felsic (dacite).
Is diorate a metamorphic rock?
No, diorite is a simply an igneous rock with lots of mafic minerals and quartz.
What is a mafic rock and what color is it?
A Mafic rock is a type of igneous rock that is rich in Iron and Magnesium instead of silica. The rocks are also darker in color like Basalt.
Is a limestone mafic?
No. The terms mafic and felsic apply to igneous rocks. Limestone is a sedimentary/biochemical rock and so cannot be said to be mafic, felsic, or intermediate.
