Is lava butte basaltic or granitic lava flow?
A lava butte is generally basaltic lava. Granitic lava flows (called rhyolitic when they form at the surface) are rare and do not cover much ground.
How is basaltic lava different from granitic lava?
Basaltic lava is far less viscous, has less silica, erupts at a higher temperature and is denser than granitic lava (properly called rhyolitic lava when it is on the surface). Basaltic lava is composed primarily of pyroxenes and calcium rich plagioclase with small amounts of olivine. Rhyolitic lava primarily contains alkali feldspars and quartz.
Which is volcanic lava rock basaltic or granitic?
The most common type of lava is basaltic. However some lavas may be andesitic or ryolitic. Rhyolite is the extrustive equivalent of granite.
What type of lava does Mt Etna have?
Granitic with a high water content, resulting in powerful steam explosions during eruptions.
What kind of magma does Yellowstone have?
The magma is primarily granitic/rhyolitic, but there are occasional basaltic lava flows.
Does granitic lava come out of a cinder cone volcano?
No. Cinder cones erupr basaltic and occasionally andesitic lava. "Granitic" lava, called rhyolitic when it is erupted, erupts primarily from composite volcanoes (also called stratovolcanoes), and some caldera volcanoes.
Magma that is low in silica and produces nonexplosive eruptions is called?
That would be basaltic magma.
What kind of lava does a lava volcano have?
The textbook answer would be granitic or rhyolitic lava. In reality composite volcanoes are highly variable, erupting the full range from basaltic to rhyolitic (granitic) materal and everything in between includin andesite and dacite. One composite volcano in Africa erupts unique carbonatite lava.
Copper is found in what type of rock?
Copper can be found in Granitic and Basaltic rocks.
Why are granitic magmas thicker than basaltic magmas?
granitic magmas contain more silica than basaltic magmas.
Is granitic magma dark or light?
granitic is light, basaltic is dark.
Why is it that pahoehoe and AA lava are more frequent in shield volcanoes than in composite volcanoes?
Aa and pahoehoe lavas are both basaltic in composition. The lava from composite volcanoes is likely to be granitic.
