What else can I help you with?
It is generally true that igneous rocks are composed of what type of mineral?
igneous rocks are composed of silicate minerals
Is aluminium in igneous rocks?
Yes. Aluminum-based minerals occur in all three of the main rock types, including igneous rocks.
Can one magma produce several different igneous rocks having different minerals?
Yes, it is possible for one magma to produce several different igneous rocks with different mineral compositions. This can occur when the magma undergoes different cooling rates or crystallization processes within the Earth's crust, resulting in the formation of various igneous rocks with distinct mineral assemblages.
How do igneous rocks form into metamorphic and sedimentary rocks?
Igneous rocks can form metamorphic rocks by being subjected to high heat and pressure, causing recrystallization of minerals. Igneous rocks can also weather and erode to form sediment, which can then be deposited, compacted, and cemented to form sedimentary rocks.
Can a single magma can produce several different igneous rocks having different mineral compositions?
Yes; through the process know as fractional crystallization, which changes the composition of the magma, therefore changing the minerals that eventually crystallize from it. Fractional crystallization occurs largely from the varying temperatures at which minerals crystallize.
How are minerals arranged in igneous rocks?
Most igneous rocks have a relatively homogenous mix of minerals which are interlocked.
Igneous rocks were formed from what minerals?
Igneous rocks are formed from minerals such as quartz, feldspar, pyroxene, and olivine. These minerals solidify from magma or lava as it cools and hardens, resulting in the formation of igneous rocks.
How is igneous depended on minerals?
because racks are rocks and minerals are minerals
Why don't igneous rocks look like magma rocks if igneous rock is formed from magma?
Because that is the very definition of igneous rock.
It is generally true that igneous rocks are composed of what type of mineral?
igneous rocks are composed of silicate minerals
Rocks which contain a variety of minerals are examples of a?
Igneous Rocks
Why can two igneous rocks have the same name minerals but different names?
Although chemically equivalent, they would be different in their method of formation. Granite is an intrusive igneous rock, cooled from magma under the surface. The rock rhyolite is the chemical equivalent of granite, but formed on the surface, making it an extrusive igneous rock. Intrusive rocks have larger crystals.

What type of rock forms from a melt by crystallization?
igneous rocks- rocks that are formed from melted minerals. ore-a rock that has a large amount of minerals.

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.
Is igneous rock made out of minerals?
No it is not. Sedimentary rocks are made of minerals.
