汶川地震与山崩地裂的极高压甲烷天然气成因和机理
|
摘要
笔者提出和论证了,汶川地震是由地壳深部一股海量异常高密度、高压甲烷天然气体突然破裂,逃出其闭圈围岩,再沿龙门山深大叠瓦状推覆断裂和不整合接触带,高速运移、膨胀、破裂和喷出岩层和断层造成的。山崩是一股高压气体高速运移到坚硬岩体山坡内部,将它们胀裂和快速推移造成的。地裂是一股高压气体高速运移到松软土体平地内部,将它们顶起变形和快速拉剪断裂造成的。
This paper presents and shows that Wenchuan earthquake of May 12,2008was caused by the rapid migration and expansion of a large amount of highly pressurized and dense methane gas mass in crustal rock masses.The dense gas mass was trapped in deep crustal rock masses.Because of increase in its pressure and mass,the dense gas mass suddenly ruptured the crustal rocks at deep Longmenshan faults with high compressions.A part of the dense gas mass escaped the trap and rapidly migrated from deep crustal rock to shallow crustal rocks along the faults,contacts and beddings and expanded the crustal rock masses.The expanding power of the dense gas that migrated into some isolated hard rock slopes caused the rock avalancherock debris flows at mountains.The expanding power of the dense gas that migrated into some isolated soil river beds and slopes caused the co-seismic ruptures at ground surfaces.
