Abstract

Aprimordial origin of terrestrial hydrocar-bons and a source of them at great depth, providing food for a vigorous microbiology at shallower depths—this is the viewpoint for which much evidence has been presented here. It is clear, however, that additional confirmation of the deep-earth gas theory and the deep hot biosphere theory will be required before they become generally accepted. Several types of investigations can be undertaken to acquire such confirming evidence.
