Short summary
We present a new case study on the role of brittle precursors in nucleating shear zone. Our studied sample shows a high-pressure, low-temperature (HP/LT) microscale ultramylonite developed by brittle precursors induced during deformation within a host HP/LT granitic mylonite. We infer that the studied structures may be considered as a small-scale example of fault structures related to stick-slip strain accommodation during subduction of continental crust.
