Which Is Denser Basalt Or Granite

By comparing the class averages i found that had a greater density than.

Which is denser basalt or granite.

Rock density is very sensitive to the minerals that compose a particular rock type. Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks. 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. Granite is an igneous plutonic rock which is.

All rocks of igneous origin consist of magma or molten earth that finds its way up to. The trick is to heat the basalt back up again so it can melt and give the iron another shot at the core. It is common both on earth and other planetary bodies. Basalt is an igneous volcanic rock that forms commonly in oceanic crust and parts of continental crust.

It wants to be there and heat is the key which unlocks the door. Basalt is denser than granite because basalt is a an oceanic type of rock so it has had more pressure from the ocean making it denser than granite because granite is a continental type of rock. By carrying out experiments similar to the one you just performed scientists have determined the density of basalt ocean crust to be 3 0 g ml and the density of granite continental crust to be about 2 7 g ml. Sedimentary rocks and granite which are rich in quartz and feldspar tend to be less dense than volcanic rocks.

And if you know your igneous petrology you will see that the more mafic rich in magnesium and iron a rock is the greater its density. Its principle minerals include pyroxene feldspar and olivine.
