AB  - Recent researches suggest participation of minerals in the formation of life 
      under primordial conditions. Among all of the minerals, quartz seems to be one of 
      the most probable to take part in such processes. However, an external source of 
      energy is needed, e.g. electric discharge. A device simulating the proposed 
      conditions was designed and was used to simulate prebiotic conditions. 
      Investigation of processes occurring during the stimulation of quartz with 
      electric discharge was studied by means of Ultraviolet-visible (UV-VIS) 
      spectroscopy, in order to monitor the generation kinetics of free radicals. 
      Additionally, infrared spectroscopy was applied to identify chemical reaction 
      products created in a solution of alanine or glycine, in the presence of quartz 
      treated with electric discharge. Formation of increased amounts of free radicals, 
      compared to experiments performed without quartz and/or amino acid, is reported, 
      along with identification of possible degradation products of alanine. No 
      synthetic reactions were observed.
