Carbon dioxide and methane emissions from calcareous-marly rock under stress: experimental tests results
gas geochemistry earthquake precursors greenhouse gases
2015/9/10
The identified emissions of abiogenic carbon dioxide, carbon monoxide and methane are generally attributed to
volcanic activity or to geochemical processes associated with thermometamorphic effects. ...
