What is the most dense type of rock?
The heaviest rocks would be those that are made up of dense, metallic minerals. Two of the heaviest or densest rocks are peridotite or gabbro. They each have a density of between 3.0 to 3.4 grams per cubic centimeter. Interestingly, peridotite are the rocks that naturally occurring diamonds are found in.
What rocks are dense?
Density of Common Rocks
- Igneous and metamorphic rock are generally more dense than sedimentary rocks.
- Mafic igneous rocks are generally more dense than felsic igneous rocks.
- Higher metamorphic grade rocks such as eclogite and amphibolite are more dense than low grade metamorphic rocks such as slate and phyllite.
What is the densest igneous rock?
Two of the heaviest or densest rocks are peridotite or gabbro. They each have a density of between 3.0 to 3.4 grams per cubic centimeter.
What are the densities of different types of rock?
Rock Densities Rock Density Rock salt 2.5–2.6 Sandstone 2.2–2.8 Shale 2.4–2.8 Slate 2.7–2.8
Which is more dense metamorphic rock or igneous rock?
Igneous and metamorphic rock are generally more dense than sedimentary rocks. Mafic igneous rocks are generally more dense than felsic igneous rocks. Higher metamorphic grade rocks such as eclogite and amphibolite are more dense than low grade metamorphic rocks such as slate and phyllite.
Which is the most dense mineral in the world?
A very small volume of that minerals has a high mass making its density come in at 11.37 g/cm3. However, actually the most dense mineral is Iridium with a density of 22.65 g/cm3. Now to answer which is most dense rock. For rocks density is measured by specific gravity (rock is compared to the density of water).
Which is the densest rock in the ocean floor?
The densest rock types are mafic igneous rocks. Mafic igneous rocks are rocks containing less silica than felsic igneous rocks. Basalt is an example of a mafic igneous rock. Basalt makes up much of the ocean’s floor.
