摘要
活动断裂带是防震减灾工作中的研究重点。目前,对于活动断裂带断层泥的研究集中在矿物学、显微构造方面,无法直接运用于地震短期临震预报。而活动断裂带的流体地球化学研究虽有利用CO_2异常进行地震临震预报的成功案例,但无法筛选与地震活动直接关联的异常指标,缺乏异常气体与地震活动关联的理论解释。本文旨在总结上述两个方向上的研究,对于活动断裂带断层泥研究与流体地球化学结合的可能性进行探讨。
Active fault zones are the major research direction in earthquake prevention. Recent researches on fault gouge in active fault zones focus on mineralogy and micro-structure, which can＇t be used to short-and temporary- term earthquake forecast. There are successful cases in short-term and temporary-term earthquake forecast by moni- toring C02 concentration through fluid geochemistry researches. However, it is limited to further studies because of lack of theoretical explanations between abnormal gas index and seismic activities. There are not directed abnormal gas index. This paper aims at summarizing previous researches in both directions and make discussions about com- bination possibilities between fault gouge researches and fluid geochemistry in active fault zones.
