Where is andesitic magma found?
Andesite can be found around volcanoes with magma of intermediate composition, usually near subduction zones.
Is pumice andesitic?
Not necessarily. Pumice can be andesitic, but it may be rhyolitic or dacitic.
What is the difference in composition between a dacite and an andesite?
Dacite is more felsic in composition, containing more silica.
What is the difference between andesite and basalt?
Both andesite and basalt are volcanic rocks. Basalt is denser and generally darker than andesite. It has a lower silica content and more iron and magnesium. It most often forms from pahoehoe or a'a lava flows and occasionally scoria cinders. Andesite forms from more slica-rich material and is often found in the form of ash, pumice, or volcanic bombs. It may also sometimes form block lava flows, which are more viscous that a'a or pahoehoe.
What igneous rocks have a mineral composition between that of granitic and basaltic rocks?
Andesitic igneous rock.
Where is andesitic magma found?
Andesite can be found around volcanoes with magma of intermediate composition, usually near subduction zones.
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 kind of lava flows from Popocatepetl?
Popocat?petl produces a mixture of andesitic and dacite lava in the current cycle of activity. Andesitic, or Basaltic Andesite, is black volcanic rock that contains 55% silica. Dacite, on the other hand, is an igneous, volcanic rock that has a composition that is between Andesite and Rhyolite.
Are Basaltic lavas are generally hotter and more viscous than andesite lavas?
No. Basaltic lavas are hotter and less viscous than andesitic lavas.
Are Basaltic lavas generally hotter and more viscous than andesite lavas?
Basaltic lavas are hotter, but less viscous than andesitic lavas.
What is the main difference between andesite and diorite?
Both are igneous rocks of intermediate coposition.
Is andesite sandstone?
No. Andesite is a volcanic rock.
Is pumice andesitic?
Not necessarily. Pumice can be andesitic, but it may be rhyolitic or dacitic.
What is the difference in composition between a dacite and an andesite?
Dacite is more felsic in composition, containing more silica.
How old is andesite?
Andesite is not any age in particular. Some deposites of andesite may be hundreds of millions of years old. However, since andesite is volcanic, some andesite rocks may only be minutes old.
Is andesite a mineral?
No. Andesite is an extrusive igneous rock.
Is Andesite an igneous?
Yes. Andesite is an extrusive igneous rock.
