Which minerals are not present in felsic type igneous rocks but are present in mafic type igneous rocks?
Mafic igneous rocks typically contain minerals like olivine, pyroxene, and amphibole which are not commonly found in felsic igneous rocks. These minerals have higher concentrations of iron and magnesium and form at higher temperatures as compared to the minerals present in felsic rocks.
What are 2 elements that can be found in both olivine and pyroxene?
Silicates.
What are the common minerals in ignous rock?
Igneous Rocks have many different mineral compositions.---- * Felsic-High in silica,low density,light colored* Mafic-less silica than felsic,dark colored,higher density than felsic * Ultramafic-lowest content of silica
What minerals are found in the asthenosphere?
The minerals found in the asthenosphere are primarily olivine, pyroxene, and garnet. These minerals have high melting points and are able to withstand the high temperatures and pressures present in the asthenosphere.
what are the 2 minerals present in mantle of the earth?
The two primary minerals found in the Earth's mantle are olivine and pyroxene. Olivine is a magnesium iron silicate, while pyroxene is a group of silicate minerals containing varying amounts of iron, magnesium, and calcium. These minerals are crucial in understanding the mantle's composition and behavior, as they play a significant role in the mantle's physical properties and dynamics.

Mafic igneous rocks typically contain minerals like olivine, pyroxene, and amphibole which are not commonly found in felsic igneous rocks. These minerals have higher concentrations of iron and magnesium and form at higher temperatures as compared to the minerals present in felsic rocks.
Olivine and pyroxene are commonly found in igneous rocks that are?
Olivine and pyroxene are commonly found in igneous rocks that are mafic in composition. These minerals indicate that the rock formed from magma with a higher iron and magnesium content. Mafic igneous rocks tend to be dark in color and have higher densities compared to felsic rocks.
What are 2 elements that can be found in both olivine and pyroxene?
Silicates.
Which minerals are found in basalt and gabbro?
Basalt contains minerals such as plagioclase feldspar, pyroxene, and olivine. Gabbro also contains plagioclase feldspar and pyroxene, but generally has a coarser texture due to slower cooling rates underground.
What igneous rock contains mostly pyroxene and olivine?
Ultramafic igneous rocks are comprised mostly of olivine and pyroxene. Examples include peridotite (pegmatic and porphyritic) and komatite.
What minerals are found in mafic rocks?
mafic rocks can be made up of orthoclase feldspar and quartz
Which minerals are found in the igneous rocks gabbro and basalt?
Gabbro and basalt are both mafic igneous rocks and contain minerals such as pyroxene, plagioclase feldspar, and olivine. Gabbro typically has a coarser grain size compared to basalt, which has a fine-grained texture due to its rapid cooling at the Earth's surface.
Which material will most likely be found in the mantle?
Olivine.
Which pair of minerals is most likely to be found in felsic rock?
Quartz and feldspar are the most likely pair of minerals found in felsic rock. Felsic rocks are rich in silica, which forms minerals like quartz, and feldspar is another common mineral found in these rocks.
