Is rhyolite silica rich or silica poor?
Rhyolite is silica-rich, containing over 70% silica. It is an extrusive igneous rock with a fine-grained texture that forms from the rapid cooling of magma rich in silica content.
What is Krakatoa a silica rich or a silica poor?
Krakatoa is silica-rich, meaning it contains a high amount of silicon dioxide (silica) in its composition. This high silica content is associated with explosive volcanic eruptions due to the interaction between silica and magma.
What magma is rich in feldspars and silica?
no its the least silica rich of granitic and andesitic magma.
Is obsidian made of silica?
Not entirely, though it is rather rich in silica.
Is scoria mafic?
Mafic, infact it is often refered to as: "the mafic version of pumice"
Are scoria and rhyolite the same in mineral composition?
Rhyolite is a rock type that is categorized by mineral composition. Scoria is a textural rock type. Like, Rhyolite can be smooth, or it can be scoria (sharper, bumpier, lots of vesicles).Think of it as a rock adjective.
Was krakatau's erupted by lava rich in silica or lava low in silica?
lava rich in silica
Is rhyolite silica rich or silica poor?
Rhyolite is silica-rich, containing over 70% silica. It is an extrusive igneous rock with a fine-grained texture that forms from the rapid cooling of magma rich in silica content.
What is Krakatoa a silica rich or a silica poor?
Krakatoa is silica-rich, meaning it contains a high amount of silicon dioxide (silica) in its composition. This high silica content is associated with explosive volcanic eruptions due to the interaction between silica and magma.
What kind of silica do strato volcanos have?
silica-rich magma
What are silica rich and thick magma is what?
Silica is sand dust.
What magma is rich in feldspars and silica?
no its the least silica rich of granitic and andesitic magma.
Is calcite silica rich or silica poor?
Calcite does not contain any silica. It is a carbonate mineral.
Is obsidian made of silica?
Not entirely, though it is rather rich in silica.
Where are volcanoes with silica-rich and quartz-rich rocks found?
Italy
Is scoria mafic?
Mafic, infact it is often refered to as: "the mafic version of pumice"
Is scoria a fine grained rock?
Scoria is a volcanic igneous rock that is composed of approximately 50% silica and 10% calcium oxide and lesser contents of potash and soda. Its hardness on the Mohs scale is 5 - 6.
