Abstract

As an example of core analysis carried out in active fault drilling programs, we report the procedures of core handlings, on the drilling site and non-destructive characterization in the laboratory. This analysis was employed on the core samples taken from Hole B of the Taiwan Chelungpu-fault Drilling Project (TCDP), which penetrated through the active fault that slipped during the 1999 Chi-Chi, Taiwan earthquake. We show results of the non-destructive physicale property measurements carried out at the Kochi Core Center (KCC), Japan. Distinct anomalies of lower bulk density andistinct higher magnetic susceptibility were recognized in all threey fault zones encountered in Hole B. To keep the core samples in good condition before they are used for various analyses is crucial. In addition, careful planning for core handling and core analyses is necessary for successful investigations.
