Answer 2

What Is The Heaviest Rock

Answer 3

The heaviest rock would be one composed only of Iridium - a mineral with a density of 22.7 g/cc. (Note that a "rock" can be composed of one or more minerals.) Iridium being quite rare, some other more common minerals that are very dense include - platinum at 18.0 and gold at 17.65 g/cc. Native gold nuggets or "rocks" are found when panning for gold, so I would suggest that Gold is your best answer to this question.



As to the question of Gold being a rock or not, yes it is a mineral, and yes it can be considered a rock just the same as rock salt (which is also composed of one mineral) is considered a rock and a mineral. The geological definition of rock is

"mineral matter of variable composition, consolidated or unconsolidated, assembled in masses or considerable quantities in nature, as by the action of heat or water."

Answer 4

Iridosmine would probably be the heaviest of all naturally found substances:

Answer 5

You did say "rock" correct? Well gold is not a rock. Also, when you say "world", do you mean Earth or anywhere in the solar system, etc?
