Basalt Granite Density

Basalt solid weighs 3 011 gram per cubic centimeter or 3 011 kilogram per cubic meter i e.

Basalt granite density.

Some meteorites have low densities 3 0 g cm 3 but such meteorites are rare among meteorites. Granite is 70 silicon. Some basalts are quite light coloured due to a high content of plagioclase and these are sometimes described as leucobasalts. This is why the continental crust mostly composed of granite floats on oceanic crust made mostly of basalt.

In imperial or us customary measurement system the density is equal to 187 9706 pound per cubic foot lb ft or 1 7405 ounce per cubic inch oz inch. Gabbro s density ranges from 2 7 3 3 g cm 3. The day after the lab is a good time to question the students about the significance of rock densities. Density fractions from the granite and the basalt samples respectively figure 1.

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. The density of basalt is normally between 2 8 and 3 0 g cm 3. The 2 g cm 3 material of the granitic samples was separated into two fractions bu t in anticipation of the possible presence of low density allophanic minerals in the basaltic soil the 2 g cm 3. For example limestone 2 6 g cm 3 or less quartzite 2 7 g cm 3 and granite 2 7 2 8 g cm 3 are all common low density rocks.

Since gabbro and basalt are made of the same minerals their densities are similar. Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks. Basalt is usually dark grey to black in colour due to a high content of augite or other pyroxene minerals but can exhibit a wide range of shading. The average density of basalt is 2 9 g cm 3.

This density varies with the type of minerals that compose it. The density of basalt one of the most common kinds of terrestrial volcanic rocks can be as high as 3 0 g cm 3. Density of basalt solid is equal to 3 011 kg m.
