Slip zone dynamics-inversion analysis from intra-slip-zone materials

摘要利用钻穿车笼埔断层之岩心，探讨大震能量消散模式。总耗散能被简单地假定为摩擦产生的热能和滑移带中矿物颗粒粉碎产生的断裂能之和。然而，分析的进展澄清，化学过程，如溶解-沉淀主要是由颗粒粉碎激活。滑移带内流体与破碎颗粒之间的反应所激活的动态化学过程是一个尚未认识到的因素。我们正试图解决地震滑动过程中的化学过程。

Mode of energy dissipation by an large earthquake is examined by using drilled core penetrating the Chelung-pu Fault, being activated by 1996 Chi-chi earthquake, Taiwan. Total dissipated energy was simply assumed as sum of heat energy by friction and fracture energy by pulverization of mineral grains contained in the slip zone. Progress of analysis clarified, however, chemical process, such as dissolution-precipitation is dominantly activated by grain comminution. Dynamic chemical process activated by reaction between intra-slip zone fluid and comminuted grains is an as-yet-unrecognized factor. We are trying to solve chemical process during seismic slip.
