What else can I help you with?
What magma is silica-rich thick magma?
An acid magma or a granitic magma.
Is granitic magma dark or light?
granitic is light, basaltic is dark.
Is basaltic magma or granitic magma hotter?
Baslatic magma is hotter.
What does granitic magma contain a lot of?
Silica.
When equal amounts of a basaltic and granitic magma mix what is the resulting magma?
basaltic
Is granitic magma very silica-rich.?
Yes
Do cinder cone volcanoes have granitic magma?
No. Cinder cones are formed by basaltic magma.
At what depth does granitic magma form?
Granitic magma forms at relatively shallow depths, typically between 1 and 10 kilometers beneath the Earth's surface. This type of magma is formed through the partial melting of continental crust, which is composed mainly of granitic rocks.
Why does granitic magma cause explosive eruptions?
Granitic magma is highly viscous (resists flow). This high viscosity results in the entrapment and buildup of gases which create explosive eruptions.
What kind of magma does Yellowstone have?
The magma is primarily granitic/rhyolitic, but there are occasional basaltic lava flows.
What are granitic rocks?
Granitic rock is intrusive igneous rock, meaning that it has been formed from the slow cooling of magma underground and will have visible crystals. Granitic, in general, refers to a mineral composition that is felsic in nature, meaning it consists of 69% or more silicate minerals, like quartz, alkali feldspars, and micas.
What kind of rock is likely to form where the heat from the granitic magma is conducted to the limestone country rock?
The metamorphosed limestone will most likely be a skarn or marble, both formed from contact with an intruding granitic magma.
