The work describes an investigation of the outgassing characteristics of diabase rock crushed to a gradation equivalent to a fine sand. Materials were heated in air to various temperatures and for several exposure periods and were then placed in a high vacuum chamber for pump down. The variation of pressure with time was plotted and the effect of nitrogen overlays between successive pump downs were evaluated. The one-dimension diffusion equation was solved to indicate the way in which pressure varies with depth. Author
