Feb 28, 2018· Gabbro rocks are coarse-grained and the crystals are in the size range of 1 mm or greater. They are dense greenish or dark-colored rocks. They possesses high density and low electrical resistivity. They have low levels of radioactive elements like potassium, thorium.


Igneous rocks are formed by the crystallisation of a magma. The difference between granites and basalts is in silica content and their rates of cooling. A basalt is about 53% SiO2, whereas granite is 73%. Intrusive, slowly cooled inside the crust. (Plutonic rock = formed in the earth). Large crystals. Granite. (Continental crust) Density 2.7-2.8.

Specific Gravity Chart. Specific gravity is a way to express the relative density of a gemstone. It is measured as the ratio of the density of the gemstone to the density of water. It is expressed as a number that indicates how much heavier the gemstone is compared to an equal volume of water.


Gabbro can be polished to a brilliant black luster. Brightly polished gabbro is used to make cemetery markers, kitchen counter tops, floor tiles, facing stone, and other dimension stone products. It is a highly desirable rock that stands up to weathering and wear. In the dimension stone industry, gabbro is sold under the name "black granite ...


the density of gabbro - dbmaligaon.in. How is the density of Rhyolite likely to compare with … Nov 14, 2007· Best Answer: Rhyolite and granite are less dense than their mafic counterparts, basalt and gabbro.


Gabbro (/ ˈ ɡ æ b r oʊ /) is a phaneritic (coarse-grained), mafic intrusive igneous rock formed from the slow cooling of magnesium-rich and iron-rich magma into a holocrystalline mass deep beneath the Earth's surface. Slow-cooling, coarse-grained gabbro is chemically equivalent to rapid-cooling, fine-grained basalt. Much of the Earth's oceanic crust is made of gabbro, formed at mid-ocean ...

Aug 20, 2015· * The bulk density is the mass of the material related to a specific volume and for cement is normally expressed as “kilograms per cubic metre”. * The bulk density reflects the volume taken up by the cement plus any air trapped between the p...


Basalt, solid weighs 3.011 gram per cubic centimeter or 3 011 kilogram per cubic meter, i.e. density of basalt, solid is equal to 3 011 kg/m³. In Imperial or US customary measurement system, the density is equal to 188 pound per cubic foot [lb/ft³], or 1.74 ounce per cubic inch [oz/inch³] .

The density measured is the bulk density d b. The total mass then becomes: Total mass = V T d b = V T d f + (1- ) V T d ma. So we have a formula giving the Mixing Law for density, which represents bulk density in terms of the porosity, pore fluid density and the matrix density: d b = d f + (1-) d ma


Nov 10, 2008· Best Answer: Yes. If I remember correctly the density of gabbro is 3.3 g/cc and the density of granite is 2.8 g/cc. The way to tell is to cut the two rocks into cubes of 1 cm sides and weigh them. You will find out that the gabbro weighs more. Since most schools don't have access to …

The density difference between granite and gabbro has an important consequence that we can illustrate by simple experiment. If we float a piece of hardwood (like oak) and and a piece of softwood (say, pine) of equal dimensions in a bucket of water, we see that the hardwood rides lower than the pine.

Gabbro is an intrusive igneous rock, coarse grained, dark coloured and consists mainly of calcium rich plagioclase feldspar and clinopyroxene.Minor amount of olivine, biotite, magnetite, apatite, ilmenite and orthopyroxene can also be the constituent mineral. Gabbro is very low on silica content thus have little to no quartz content.

Jan 15, 2019· For example, the density of a one-inch cube of iron is much greater than the density of a one-inch cube of cotton. In most cases, denser objects are also heavier. The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water.


Since gabbro and basalt are made of the same minerals, their densities are similar. 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.


Gabbro Gabbro is a dense, mafic intrusive rock. It generally occurs as batholiths and laccoliths and is often found along mid-ocean ridges or in ancient mountains composed of compressed and uplifted oceanic crust. Gabbro is the plutonic equivalent of basalt.


Gabbro often contains valuable amounts of chromium, nickel, cobalt, gold, silver, platinum, and copper sulfides.. Ocellar (orbicular) varieties of gabbro can be used as ornamental facing stones, paving stones and it is also known by the trade name of 'black granite', which is a popular type of graveyard headstone used in funerary rites.
