Properties of Basalt and Granite Compare Rocks

What Is the Difference Between Basalt and Granite

Granite is an intrusive rock that is formed when magma cools inside the crust. This slow cooling gives time for crystals to grow, making it more coarsely grained than an extrusive rock. This coarse grain makes granite a favorite of rock climbers. Basalt, on the other hand, has a smooth texture from rapid cooling, usually by water. Granite is a

Why Does Basalt Weather Faster Than Granite? Sciencing

Both basalt and granite are igneous rocks, which are made up of magma or molten lava after it cools. While both basalt and granite are similar to each other, they also have characteristics that distinguish them from each other. Basalt Formation. Basalt forms when magma from the ocean surfaces through the crust. It is a very prominent rock and

Basalt Wikipedia

Basalt (US: / b ə ˈ s ɔː l t, ˈ b eɪ s ɒ l t /, UK: / 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 magnesium-rich and iron-rich lava exposed at or very near the surface of a terrestrial planet or a moon.

Geology rocks and minerals

Basalt Basalt is a mafic extrusive rock, is the most widespread of all igneous rocks, and comprises more than 90% of all volcanic rocks. Because of its relatively low silica content, basalt lava has a comparatively low viscosity, and forms thin flows that can travel long distances.

is basalt harder than granite? Yahoo Answers

May 06, 2007· So the hardness of a rock is determined by the minerals, and in a coarse grained rock like a granite, the hardness can vary widely. The hardest mineral in granite (quartz) is harder than the hardest mineral in basalt (feldspar), but that's not enough to say that granite is conclusively harder than basalt. The resistance to breaking of a rock

what is the hardness of basalt? Yahoo Answers

Nov 21, 2009· Basalt is composed mostly of plagioclase and pyroxene. Each of those minerals has a different hardness, and geologists never use the hardness of a "rock" to determine what kind of rock it is. Basalt is usually much finer grained than granite so it would be virtually impossible to determine the hardness of the individual mineral crystals.

Basalt and Granite

Basalt is commonly very fine grained, and it is nearly impossible to see individual minerals without magnification. Basalt is considered a mafic silicate rock. Among other characteristics, mafic minerals and rocks are generally dark in color and high in specific gravity. This is in large part due to the amount of iron, magnesium, and several
