Taiwan is located in the orogenic belt, which the active faults are widely distributed in this island. Damaged earthquakes, i.e. 1999 Chichi earthquake, occurred frequently in past hundreds years and caused vest amounts people death and properties lost. However, the researches were scarce in Taiwan for those topics. The Chelungpu thrust fault moved in 1999 provides a good opportunity to study the characteristics and origins of fault-related rocks and seismogenetic zones from the surface outcrops to subsurface drilling cores. This project is planning to spend two years for measuring physical and chemical properties as well as microbiologic analyses in core materials in matching for the Taiwan Chelungpu-fault Drilling Project (TCDP). The purpose are to understand the changes of the physical and chemical properties accompanying the earthquake cycle in the fault zone as well as fluid roles in large displacement of thrust fault. Meanwhile, collect the materials for culturing bacteria to the insight on distribution, community structure and metabolic functions for microbial communities, diversity of functional genes, in-situ microbial activities, substrata flux across lithologic units and fracture system and isotopic signatures of sulfur-related compounds preserved in geological materials and pore water, and interaction between microbes and geological materials along a depth profile in an accretionary wedge. The methods use in this project including optical, scanning and transmitted electron microscopy (OM, SEM, TEM), X-ray fluorescence analysis (XRF), ion chromatography (IC), gas spectrometry (GC) and inductivity coupled atomic-emission and plasma-mass spectrometry (ICP-AES and ICP-MS) and so on.車籠埔斷層鑽井岩芯剪切帶斷層岩石發震帶微生物Chelungpu faultdrilling coresshear zonefault-related rocksseismogenetic zonemicrobiology
