Basalt Or Granite Viscosity

Basalt is most widespread of all igneous rocks and comprises more than 90 of all volcanic rocks.

Basalt or granite viscosity. More than 90 of all volcanic rock on earth is basalt and the eruption of basalt lava is observed by geologists at about 20. None of the above. High sio2 content and high viscosity. Do you think the viscosity would be the same in each case.

Its three main minerals are feldspar quartz and mica which occur as silvery muscovite or dark biotite or both. Which resists flow more honey or water. It has relatively low silica content basalt lava has a comparatively low viscosity. In a classic paper am j sci 272 438 1972 bottinga and weill developed a.

First of all you should know the difference between lava and magma magma and lava are both molten liquid rock but magma is moltenrock produced underneath earth surface while it magma erupts on the surface of earth it is called lava. Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks. It is common both on earth and other planetary bodies. Resistence to flow c.

Variation in the viscosity of rhyolite at 1000ºc with increasing h 2o content after shaw 1965 amer. B ə ˈ s ɔː l t ˈ b eɪ s ɒ l t uk. The formation of shield volcanoes is favored by a. Basalt is an igneous volcanic rock that forms commonly in oceanic crust and parts of continental crust.

Its principle minerals include pyroxene feldspar and olivine. Granite is the most common intrusive rock in earth s continental crust it is familiar as a mottled pink white gray and black ornamental stone it is coarse to medium grained. Granite ˈ ɡ r æ n ɪ t is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Does water flow as fast as honey.

It forms from lava flows which extrude onto the surface and cool. Which fluid has a higher viscosity. All rocks of igneous origin consist of magma or molten earth that finds its way up to. Granites can be predominantly white pink or gray in color depending on their mineralogy the word granite comes from the latin granum a grain in reference to the coarse grained structure of such a completely crystalline rock.

Viscosity is a property that measures a. Variation in the viscosity of basalt as it crystallizes after murase and mcbirney 1973 geol. ˈ b æ s ɔː l t ˈ b æ s əl t is a mafic extrusive igneous rock formed from the rapid cooling of lava rich in magnesium and iron exposed at or very near the surface of a terrestrial planet or a moon.
