Iron Record: Ancient Rocks Tell the Story of Oxygen, and Life

Some iron (II) will react with sulfur, forming iron pyrite, which gets incorporated into rock. In oxygenated water, all the iron (III) forms iron oxide and the iron (II) forms iron pyrite, leaving very little iron in the water. In addition to coming in different forms, iron atoms can also have different weights.

Pyrite | Earth Sciences Museum

Pyrite seldom forms in fresh-water environments. The formation of pyrite crystals depends mainly on the iron content of the sediment. The process of pyrite formation in sediments results from the action of bacteria, which reduce sulphate ions (dissolved in the pore water) to sulphide. If there is iron present, iron sulphide crystals begin to grow.

Pyrite vs. Gold: 11 Key Differences (Never Get Wrong Again)

Pyrite has a higher specific gravity measuring 4.8-5.0, while gold weighs in at 19.3 g/cm3.

So by volume, a piece of pyrite weighs more than the same volume of gold.
