The mineralogy of basalt is characterized by a preponderance of calcic plagioclase feldspar and pyroxene. Olivine can also be a significant constituent.
Basalt varies in mineral composition. Plagioclase feldspar, pyroxene, olivine, magnetite, and ilmenite are common minerals present in basalt.
Basalt is made up of three minerals. Basalt is consist (by volume) of quartz (less that 20 percent), feldspathoid (less than 10 percent), and plagioclase (65 percent the least).
Pyroxene and calcium-rich plagioclase are the most abundant minerals. Some basalt contains olivine.
Basalt is mainly comprised of calcic plagioclase feldspar and pyroxene. Olivine can also occur in large amounts in basalt and a number of other minerals may appear in minor amounts.
Basalt is fine-grained so that the individual minerals are not visible, but they include pyroxene, plagioclase feldspar and olivine.

Rhyolite has a more felsic composition than basalt.
Intrusive: Extrusive Equivalent Granite: Rhyolite Diorite: Andesite Gabbro: Basalt
Rocks have a composition between that of granite and basalt
How are basalt and granite diffrerent in their origin texture and mineral composition How are the similar
It is most similar to the composition of the rock basalt.

Basalt, welcome
Rhyolite has a more felsic composition than basalt.
Andesite is considered an intermediate rock between granite (felsic igneous rock) and basalt (mafic igneous rock), based on chemical composition.

No. Basalt is a Mafic Extrusive Igneous Rock.
It is most similar to the composition of the rock basalt.
The magma and lava of Surtsey has a composition of alkali Olivine Basalt.

It is that it has high silica content
