  • In What Rock Formations Can Gold Be Found?

    2017-4-24  Intrusive rock is typically very hard and erodes slowly. This allows the surrounding rock to be worn away by wind and water, leaving only the harder rock in place. Heavy particles, such as gold, are likely to accumulate against the harder rock while the lighter materials are more easily moved away.

  • The Density of Common Rocks and Minerals -

    2020-1-23  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. This isn't as complex as you may think because water's density is 1 gram per cubic centimeter or 1 g/cm 3. Therefore, these numbers translate directly to g/cm 3, or tonnes per cubic meter (t/m 3).
