  • Serpentine, Slate, Soapstone, Sandstone, Quartzite

    More Stone Products , Quartzite is a non-foliate metamorphic rock that is created from sandstone It is composed primarily of quartz which can give these types of stones exceptional strength, density, and hardness These stones are among the most durable and gorgeous types around, however it can get pretty pricy and difficult to find.

  • The Density of Common Rocks and Minerals

    Rock density is very sensitive to the minerals that compose a particular rock type 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.
