Late Preorganic Condensation

Celestial

After losing much of it's initial hydrogen and helium atmosphere, bombardment of debris from the system's formation released vaporised gases from the meteorites themselves and from rocks in the planet, one of these products being water, cloaking the planet in a thick, hot, sooty atmosphere with water vapour clouds. They filled the planet's deepest basins and trenches with caustic water, dissolving rock salts, minerals and washing fine ash and inorganic sediment from the surface into the liquid medium.   Volatile gases in the atmosphere such as oxygen, chlorine and flourine also reacted with the rock constituents and became locked in the reaction products, such as rust, trapped in the rocks or to be buried under sedimentary layers.
