A typical case was the 1999 Chi-Chi earthquake, induced by the Chelungpu faulting which caused huge damages in property and many casualties in Taiwan. It caused a total surface rupture of about 80-90 km along the Chelungpu fault and large vertical offsets reaching as high as 8-9 m. This activity was one of the longest slip distance in the world in last century and attracted international geoscientists attention. However, how fluid-rock interaction, mechanism and energy budget of the thrust faulting act remains poorly constrained which is one of the unpredictable reasons for the earthquake. Meanwhile, the researches on microbial communities in extreme subsurface environment are the interdisciplinary hot topics which would provide insight into ecological patterns, sustainability and evolution of early biosphere. The TCDP has drilled two deep holes not only into the slip and fault zones of the Chelungpu fault but also al least 6 major ones of west Taiwan. They provide precious materials to study the characteristics, mechanism and energy budget as well as microbiology in thrust fault system. Recognizing these great scientific potentials and motivated by the need to integrate the expertise and resource from various disciplines, we propose a long-term research program that encompasses geochemistry, geology, nano-mineralogy and microbiology, and aims at better understanding the thrust fault system. This would be the first interdisciplinary platform dedicated to build a state-of-art FE-SEM with high resolution attached equipments on the materials from thrust fault system in Taiwan, and would catalyze numerous exchanges of knowledge, training and education across disciplines in the future.台灣車籠埔深鑚計畫斷層帶逆衝斷層奈米斷層泥掃描式電子顯微鏡微生物學Taiwan Chelungpu-fault Drilling Projectfault zonethrust faultnano-gougeSEM,microbiology車籠埔地震斷層的活動機制、能量釋放和生物-(總計畫及子計畫一)車籠埔地震斷層的活動機制、能量釋放和生物(2/3)
