Basalt or granite viscosity.
What is the composition of each basalt and granite.
Variation in the viscosity of basalt as it crystallizes after murase and mcbirney 1973 geol.
Which resists flow more honey or water.
Do you think the viscosity would be the same in each case.
Its principle minerals include pyroxene feldspar and olivine.
None of the above.
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.
In a classic paper am j sci 272 438 1972 bottinga and weill developed a.
Basalt is most widespread of all igneous rocks and comprises more than 90 of all volcanic rocks.
It has relatively low silica content basalt lava has a comparatively low viscosity.
Resistence to flow c.
Basalt is an igneous volcanic rock that forms commonly in oceanic crust and parts of continental crust.
Its three main minerals are feldspar quartz and mica which occur as silvery muscovite or dark biotite or both.
High sio2 content and high viscosity.
It forms from lava flows which extrude onto the surface and cool.
Variation in the viscosity of rhyolite at 1000ºc with increasing h 2o content after shaw 1965 amer.
The key difference between basalt and granite is that basalt is mostly occurring on ocean floors while granite is in the crust of the earth in all continents.

Which fluid has a higher viscosity.
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.
Does water flow as fast as honey.
Granite ˈ ɡ r æ n ɪ t is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture.
Describes the resistance to flow due to internal friction.
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.
More than 90 of all volcanic rock on earth is basalt and the eruption of basalt lava is observed by geologists at about 20.
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.
