汶川地震断裂科学钻探(WFSD)岩心中的汶川地震主滑移带。通过综合研究,确定汶川地震主滑移带厚度为100~200μm,局部形成纳米级石墨颗粒。说明断裂滑移机制以热增压为主,断层强度极低。石墨的富集可作为上地壳地震瞬时摩擦生热的标志,成为判断大地震发生的证据。对认识汶川地震及古地震判定具有重要意义。这项由中国地质科学院地质研究所李海兵研究员主持的研究成果,当选中国地质调查局、中国地质科学院2014年度地质科技十大进展,排名第十。详见本期257-269
Wenchuan earthquake rupture scientific drilling (WFSD) core Wenchuan earthquake main slip band. Through the comprehensive study, the thickness of the main slip zone of Wenchuan earthquake was determined to be 100 ~ 200μm, and the local formation of nano-scale graphite particles. It shows that the fault slip mechanism is dominated by hot pressurization and the fault strength is extremely low. The enrichment of graphite can be used as a symbol of the instantaneous frictional heat generation of the upper crust earthquake and become the evidence to judge the occurrence of a large earthquake. It is of great significance to recognize the Wenchuan earthquake and paleoearthquake. The research result chaired by researcher Li Haibing of the Institute of Geology, Chinese Academy of Geological Sciences was elected as one of the Top Ten Progress of Geological Science and Technology of China Geological Survey 2014 by the China Geological Survey and ranked 10th.
