【摘要】 本文根据近两年来在黑龙江省中西部沿断裂带逸出的H2、CO、H2S等还原性气体组合,结合C、H、S、He、Ar同位素研究,讨论了还原性气体组合的深源特征。在此基础上以安达地震为例,作者阐明了以氢气为首的还原性气体逸出与深部构造背景及其与地震的关系。深源还原性气体的逸出孕育着地壳不稳定的因素,有诱发地震和其他自然灾害的可能。地球排气作用与地震作用关系的研究在类似黑龙江省中西部大面积被第四系覆盖的地区是地震预报较为有效的手段。更多还原

【Abstract】 In this work a combination of reductive gases H2,CO,and H2S escaping along the fault belts in central west Heilongjiang Province during the last two years are studied together with isotopes of C,H,S,He,and Ar to identify the deep-origination features of those reductive gases.Recent Anda earthquake is analyzed as an example to explore the relationships between escape of reductive gases dominated by H2,the deep tectonic background,and seismology in the related area.It is concluded that escape of deep reductive gases implies factors of instability of the crust,which may also lead to earthquakes or other natural hazards.Research on outgassing of the Earth in conjunction with seismic activities could be helpful for earthquake prediction in such areas widely overlaid by Quaternary as the central west Heilongjiang Province.更多还原
