FDConverter: A Software for the Conversion of Orientation Data

Abstract

We have developed a software to convert orientation data for fault-striation analysis. The software specializes in dealing with the strike and dip of the format, e.g., N30E50E, that is common among Japanese geologists. Each fault data consist of the strike and dip of fault plane, orientation of striation, and sense of shear. If the orientation of striation is measured by its azimuth and plunge, the measurement error often shifts the orientation from the fault plane. In that case, the software calculate the angular misfit between the orientation from the fault plane. The result can be saved as a text file for later use. The software is useful not only for fault analysis but also other purposes, such as paleo-current analysis.
