Planetary Accretion, Bombardment, and Equilibration
 * Formation of the Heliosphere and planetary solar system (4.6-4.5 bya)
 * Accretion of Earths Primordial Geosphere and Atmosphere
 * Initial atmosphere of H2, He, CH4, N2, NH3, H2O, Metallic Vapors, Noble Gases. Rapid loss of lighter non-polar gases.  Gradual accumulation of volcanic outgassing - CO, CO2, H2O, H2S
 * Low abiotic concentrations of molecular oxygen scavenge electrons from other elements resulting in the formation of oxides and an anaerobic environment.
 * H2O, CO, CO2, P2O5
 * Na2O, K2O
 * MgO, CaO, Al2O3, SiO2, TiO2
 * FeO, Fe2O3, Fe3O4
 * Collisional Lunar Event and extraterrestrial bombardment (4.5-3.9 bya)
 * Last impactor large enough to completely boil off Earths oceans. and the first "prebiotic broths", strikes. Large impactors are still capable of boiling the Earths Oceans periodically, but the Great Bombardment is waning and the primary solvent base of the ocean is established permanently.
 * The Ten Million Year Rain - The Condensation of Atmospheric Water Vapors and establishment of the hydrosphere.
 * The final "Prebiotic Soup" of organic and inorganic constituents in a mineral-rich aqueous broth cooked by geological and atomospheric processes surge through the fissures of the Earths crust and mantle and then work their way back to the surface. This solution becomes increasingly dilute as water continues to condense out of the atmosphere and enters the hydrosphere. Non-polar substances partition from aqueous phase and give rise to prebiotic liposphere.
 * Establishment of permanent oceans/beginning of dynamic equilibration of the Geosphere/Hydrosphere (3.9 bya) - [Mantle-Crustal-Atmospheric Redox Couple, Na+,K+,Cl- osmolality]
 * Fe2+ and H2S abundant in seawater precipitates Iron Sulfide.
 * Primordial upwelling of inorganic and abiotic thiorganic molecules from hydrothermal and volcanic sources flow over precipitated Iron Sulfide chimney/vent systems in a continuous flux.
 * Substantial seawater concentrations of Ca2+,Mg2+ limits free/soluble phosphate. Phosphate is sequestered as precipitates of Mg, Ca, Fe, and other metals.
