Andesitic rocks have mineral compositions between those of basaltic rocks and?
granitic
What type of magma has a high silica content?
rhyolitic magma has a lot of silica and water vapors... thanks for asking answers.com ;)
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.
What magma is rich in feldspars and silica?
no its the least silica rich of granitic and andesitic magma.
What is dactic lava composition?
I do not know specifically but it is fairly high in silica making it rather viscous and good for trapping/holding gas. Dactic magmas can be either exlposive volcanic events or just be mild lava flow depending on the amount of trapped gas. Dactic sits between Rhyolitic and Andisitic in compostion. Rhyolitic is highest in viscosity have the most Silica then Dactic, andesitic then basaltic having the least silica.
What igneous rocks have a mineral composition between that of granitic and basaltic rocks?
Andesitic igneous rock.
Andesitic rocks have mineral compositions between those of basaltic rocks and?
granitic
What is same between basaltic and andesitic rock?
Both are classified as igneous rock.
What is the average composition of rocks comprising a large composite cone or stratovolcano?
The average composition of rocks comprising a large composite cone or stratovolcano is andesitic magma. It is the intermediate type between basaltic and dacitic magma.
What is igneous that have mineral composistions between those grantic and basaltic rocks?
andesitic rock
What does it mean to have andesitic composition?
Rocks have a composition between that of granite and basalt
Definition for andesitic composition?
the composition of igneous rocks lying between felsic and mafic.
What type of magma has a high silica content?
rhyolitic magma has a lot of silica and water vapors... thanks for asking answers.com ;)
What is the difference between basaltic magma and silicic magma?
Granitic rocks are intrusive, which means they crystallized underground. Basaltic rocks are extrusive, meaning they crystallized above ground. Also, basaltic rocks are more mafic, and granitic rocks are more felsic.
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.
What is Magma that is high in silica and produces explosive eruption is called?
Rhyolitic magma. Boom! Basaltic magma is its exact opposite, while andesitic magma is in between the two.
What is the difference between oceanic and continental plates?
Continental plates are thicker and less dense. Continental plates are mainly granitic in composition. Oceanic plates are mainly basaltic in composition. The rock of continental plates is on average, much older than the rock of the oceanic plates. The oceanic plate underlies the oceans, and the continental plate makes up the land masses. Continental plates do not subduct at convergent plate boundaries.
