Origin of precursors of organic molecules during evaporation of meteorites and rocks

The early Earth's atmosphere and hydrosphere was formed in parallel with the Earth's growth. Laser pulse effect on various rocks and meteorites was used to simulate the melting and evaporation processes of planetosimal matter caused by high-speed impact. In experiment the residual gas mixture contains both oxide and reduced components: CO; CO 2; SO 2; H 7O; N 2, in less quantities — H 2S; COS; CS 2; various hydrocarbons from C 1 to C 6. Such composition of atmosphere is favourable for the abiogenic synthesis rather complex organic compounds. Direct formation HCN and acetic aldehyde is especially significant in the experiment.
