... A fossil is formed when soft parts of a dead animal (skin, muscles and organs) decay quickly, but the hard parts of the animal (teeth, bones and shells) are altered and then fossilized. Bones of the animal become petrified or turned into a rock like substance. This happens when water penetrates the ...

Volcanogenic massive sulfide deposits host the evidence for sulfate
... Recent researchers have suggested that the Archean oceans were sulfate poor (<0.1 mM SO42-, compared to 28 mM today), because the atmosphere was supposedly poor in O2 (pO2 < 10-6 atm) to completely oxidize the sulfur-bearing volcanic gases (H2S and SO2) and sulfide minerals in soils to SO42-. Howeve ...
