The Great Oxygenation Event (GOE), also called the Oxygen Catastrophe, Oxygen Crisis, Oxygen Holocaust, Oxygen Revolution, or Great Oxidation, was the biologically induced appearance of dioxygen (O 2) in Earth's atmosphere.he gap between the start of oxygen production from photosynthetic organisms and the geologically rapid increase in atmospheric oxygen (about 2.5â2.4 billion years ago) may have been as long as 900 million years.
Application of Oxygen Isotopes to Exploration. Abstract. Oxygen isotopes can potentially provide information on 1) temperature of mineral formation, 2) source of the aqueous fluid, 3) water/rock ratios and 4) extent of chemical equilibrium.emperature information can be extracted from isotopic analysis of mineral pairs. The oxygen isotopic composition difference, D O, between two coexisting (coprecipitated) minerals at equilibrium is only a function of temperature (Fig.
