Where do most rocks have basaltic composition?
Most rocks with basaltic composition are found in volcanic regions, such as volcanic islands and mid-oceanic ridges. They are also commonly found in continental flood basalt provinces, which are large expanses of basaltic lava flows that cover extensive areas of land. Basaltic rocks can sometimes be found in other settings as well, such as in certain types of metamorphic rocks.
Where do rocks have a basaltic composition?
Oceanic crust is made of basaltic rock. The rocks formed from hotspot volcano lavas are also often basaltic too.
Does Light-colored rocks with lower densities form from basaltic magma?
Basaltic Magmas are dark colored, heavy and are ferromagnesian in composition, so they most times do not form light colored rocks, rather, the Felsic Granitic Magma forms the light colored rocks with lower densities.
What is magma composition of Mount Tambora?
It is that it has high silica content
Andesitic rocks have mineral compositions between those of basaltic rocks and?
granitic
Are basalt rocks pyroclastic?
Usually not. Although it is possible to have pyroclastic material with a basaltic composition, most basaltic rocks are from simple lava flows.

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

How are rocks from the Highland and Maria areas of the Moon different?
The Lunar Highland rocks reflective and anothositic in composition, while the Lunar Maria are less reflective and basaltic in composition.
What is the average composition of rocks comprising a large composite cone or stratovolcano?
The average composition of rocks comprising a large composite cone or stratovolcano is andesitic magma. It is the intermediate type between basaltic and dacitic magma.
What type of magma is closer to intrusive rocks?
magma can be classified into two,magma of granitic composition(originates from lower continental crust) and magma of basaltic composition (which originates from upper mantle).Both can form intrusive rocks.
What is the composition of a rock depends on?
For igneous rocks,the composition depends on the source magma,either basaltic or granitic,For Sedimentary rocks it depends on source of sediments or nature of salts which existed in the basin from which precipitation took place, and for metamorphic rocks it depends upon the source rock.
Why are granitic igneous rocks lighter in color than basaltic rocks?
Because granitic rocks are poor in iron and magnesium, which gives basaltic rocks it dark color.
Copper is found in what type of rock?
Copper can be found in Granitic and Basaltic rocks.
Is rhyolite a basaltic composition?
No. Basalt is a low-silica igneous rock while rhyolite is high-silica. As far as volcanic rocks go, they are essentially opposites.
