Basalt typically contains a greater percentage of biotite compared to rhyolite. Rhyolite is a silica-rich volcanic rock that generally has a lower abundance of mafic minerals like biotite, while basalt, being more mafic, often includes higher amounts of biotite and other ferromagnesian minerals. Therefore, basalt has a higher percentage of biotite than rhyolite.
What else can I help you with?
Is basalt an igneous rock and how is it use full?
basalt is an extrusive igneous rock to be specific.you can use it to extract mafic minerals such as ,Biotite(used to make insulators).But as a rock it is used in construction as building material.
Basalt has a greater specific gravity than granite?
Basalt does have a greater specific gravity. Granite is not as dense as basalt.
Why does alkalic basalt contain less silica than tholeiites?
The magma that forms alkalic basalt forms under conditions with a higher fraction of partial melting that the magma that forms tholeiitic basalt. This means that the resulting alkalic melt contains a higher percentage of the minerals with a low silica content.
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 is the dark colored rock the makes up most of the oceanic crust?
Basalt
Which has a greater percentage of biotite in it rhyolite or basalt?
Rhyolite typically has a greater percentage of biotite compared to basalt. This is because rhyolite is a silica-rich volcanic rock that contains more biotite, a mica mineral, which forms in silica-rich environments. Basalt, on the other hand, is a silica-poor volcanic rock that generally contains lower amounts of biotite.
Is basalt an igneous rock and how is it use full?

Basalt has a greater specific gravity than granite?
Basalt does have a greater specific gravity. Granite is not as dense as basalt.
What is andestic?
If u are referring to andesitic basalt, lava having a greater silica content than that of basalt. Andesite is a rock.
What has the author Michael J Kunk written?
Michael J Kunk has written: 'p40sAr/p39sAr age-spectrum data for whole rock basalts, and plagioclase and biotite from tephra' -- subject(s): Basalt, Potassium-argon dating
This igneous rock is coarse-grained. The dark-colored mineral composing this rock is probably?
The dark-colored mineral in coarse-grained igneous rocks is likely to be biotite or hornblende. These minerals are commonly found in rocks like diorite, gabbro, and basalt.
Why does alkalic basalt contain less silica than tholeiites?
The magma that forms alkalic basalt forms under conditions with a higher fraction of partial melting that the magma that forms tholeiitic basalt. This means that the resulting alkalic melt contains a higher percentage of the minerals with a low silica content.
What is the Rosetta stone made of?
The Rosetta Stone is a dark grey-pinkish stone of granodiorite, although it was originally thought to have been basalt. Granodiorite is an igneous rock, rather like granite, but the presence of more biotite mica and hornblende makes it darker in appearance than granite.
Where is the Basalt Rld in Basalt located?
The address of the Basalt Rld is: 14 Midland Ave, Basalt, 81621 8305
What is a sentence using the word 'basalt'?
That rock was not Basalt, it was different. This is not a diamond, just a normal Basalt.
What type of stone is the Rosetta stone?
The Rosetta Stone is a dark grey-pinkish stone of granodiorite, although it was originally thought to have been basalt. Granodiorite is an igneous rock, rather like granite, but the presence of more biotite mica and hornblende makes it darker in appearance than granite.
How does the Rosetta stone look like?
The Rosetta Stone is a dark grey-pinkish stone of granodiorite, although it was originally thought to have been basalt. Granodiorite is an igneous rock, rather like granite, but the presence of more biotite mica and hornblende makes it darker in appearance than granite.
