Episodic concentration of gold to ore grade through Earth

Syn sedimentary marine pyrite from Mesoarchaean sediments has the highest Au content compared to any other marine pyrite from other periods, which led to the conclusion that the gold concentration in ocean water reached a peak between 3.0 and 2.7 Ga (Large et al., 2015). Non carbonaceous, unmineralised marine shale should best reflect the average composition of the eroded source rocks in
