Abstract - Summary 
(short description):
The extraterrestrial origin of carbon (C), hydrogen (H), nitrogen (N) and noble gases in natural diamonds is considered. For all methods of synthesis, diamond is formed from any carbon-containing substance always only by pulsed heating of the latter in a time measured by microseconds at the same pressures, pyrolysis temperatures lead to the formation of graphite, Pulsed heating of the C-substance under natural conditions occurs only at an impact event, which results in a high pressure (HP) and an increasing temperature (NT) induced by the rapid compression of the target rocks by a shock wave in a time measured by microseconds. Meteorites, micrometeorites, stellar dust particles, ņomets, asteroids are sources of organic matter, including gases in its composition. The main elements of the organic substance C, H, N, O, S, noble gases.
