Understanding the scaling relation of damage zone width with displacement of faults is important for predicting subsurface faulting mechanisms and luid low processes. The understanding of this scaling relationship is inluenced by the accuracy of the methods and types of data utilized to investigate faults. In this study, seismic relection data are used to investigate the throw and damage zone width of ive strike-slip faults afecting Ordovician carbonates of the Tarim intracraton basin, NW China. The results indicate that fault slips with a throw less than 200 m had formed wide damage zones up to 3000 m in width. Also, damage zone width is found to have both a positive correlation and a power-law relation with throw of two orders of magnitude, with a ratio of these values varying in a range of 2–15. The relationship between throw and damage zone width is not a simple power-law and changes its slope from small-to-larger-size faults. The results indicate that throw scales well with damage zone width for the studied faults, and hence these can be used to predict fault geometries in the Tarim Basin. The study of the wide carbonate damage zones presented here provides new insights into scaling of large-size faults, which involve multiple faulting stages.
