在《美国地球物理协会联合会汇刊》1983年6月4日最近一期的《甲烷与地震活动的联系》一文中,奥伦兰(R.S.Oremland)介绍了他认为与深部甲烷气体假说有矛盾的观测结果。其主要的事例以加利福尼亚的马默思湖火山地区附近的一次5.7级地震为依据,该地震并没有引起当地四口水泉中气体甲烷含量的任何增加。在我们发表的深部气体假说的讨论(Goldand Soter,1980,1982)中,我们提出:①火山区和非火山区都具有一个从地幔深部释放气 In a recent article in The Journal of the American Geophysical Union, June 4, 1983, “The link between methane and seismicity,” Oreran introduced what he considered contradictory to the deep methane gas hypothesis Observations. The main example is based on a magnitude 5.7 earthquake near the Mammoth Lakes volcano in California that did not cause any increase in gas methane content in the four local springs. In the discussion of our published deep gas hypothesis (Gold and Soter, 1980, 1982), we propose: (1) Both volcanic and non-volcanic areas have a well that releases gas from deep within the mantle
