“…Given the low-grade metamorphic conditions of this study, the results compare with the interpretation of results offered by Kirschner et al (1996) more than results from van der Pluijm et al 2001, which are derived from a diagenetic to very-low-grade metamorphic environment. Nemkin et al (2015) combined dates derived from folds with palaeomagnetic data to better constrain the timing of remagnetization related to folding. Although the growth of illites and magnetite were implicitly assumed to be related, there was no attempt in this paper to derive a series of linked chemical reactions that would explicitly relate the two processes.…”

Radiometric dating of fault gouges has become a useful tool for regional tectonics studies and for exploring and understanding fault and earthquake processes. Methods to define the absolute age of faults achieved a solid scientific foundation almost 25 years ago when the development and application of illite age analysis for investigating sedimentary burial and thermal histories found a new potential application – defining the age of fold-and-thrust development. Since then, the methods have benefitted from further development and incorporation of the 40Ar/39Ar micro-encapsulation method and quantitative clay mineral evaluation to distinguish polytypes (Wildfire). These refinements to the methods have improved their application in fold-and-thrust terrains and have opened up applications in normal and strike-slip fault environments. Another important development is the use of absolute dating methods in retrograde clay gouges in which clays in a fault develop from igneous or metamorphic wall rocks that contain no clays. In addition, the method has also been shown to be useful at dating folds in fold-and-thrust belts. We think the method is now an established part of the geological toolkit, look forward to future fault structural and tectonic studies that incorporate fault ages and hope that researchers continue to probe and discover ways that the method can assist fault process studies, including earthquake fault studies.
