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 is the mineral composition of syenite?

Syenite is primarily composed of alkali feldspar minerals such as orthoclase and plagioclase feldspar, along with small amounts of other minerals such as quartz, hornblende, and mica. It lacks significant amounts of calcium-rich plagioclase feldspar, which distinguishes it from granite.


What composition refers to rocks with many dark silicate minerals and plagioclase feldspar?

The composition referring to rocks with many dark silicate minerals and plagioclase feldspar is called basalt. Basalt is a fine-grained igneous rock that is commonly found in oceanic crust and volcanic islands.


What igneous rocks have a mineral composition between that of granitic and basaltic rocks?

Andesite and diorite are two common igneous rocks that have a mineral composition intermediate between granitic and basaltic rocks. Andesite is fine-grained and contains plagioclase feldspar and pyroxene minerals, while diorite is coarse-grained and composed of plagioclase feldspar, amphibole, and other minerals.


Which rock has an intermediate composition?

Andesite is a rock with an intermediate composition. It contains minerals such as plagioclase feldspar, amphibole, and pyroxene, giving it a balance between light and dark minerals. Andesite forms from the cooling of magma with a composition between basalt and granite.

What minerals does the rock granite always contain?

Granite always contains the minerals quartz, feldspar (potassium feldspar or plagioclase feldspar), and mica (biotite or muscovite). These minerals give granite its characteristic appearance and properties.

What minerals form the rocks diorite and andesite?

The minerals that form diorite include plagioclase feldspar, biotite, and hornblende. Andesite is primarily composed of plagioclase feldspar, pyroxene, and hornblende. Both rocks are intermediate in composition between granite and basalt.

What four minerals make up rocks in the intermediate family?

The four minerals that make up rocks in the intermediate family are plagioclase feldspar, amphibole (such as hornblende), biotite, and quartz. These minerals are typically found in rocks like diorite and andesite, which have a composition between felsic and mafic rocks.


Rocks that contain dark silicate minerals and plagioclase feldspar have?

Basaltic composition, commonly found in oceanic crust and volcanic islands.


What minerals are in granite but not gabbro?

Granite contains Quartz and Plagioclase Feldspar and Gabbro does not have neither if these minerals in it.


What is the chemical composition of a basalt?

The mineralogy of basalt is characterized by a preponderance of calcic plagioclase feldspar and pyroxene. Olivine can also be a significant constituent.
