Short summary
Three types of lattice distortion patterns in deformed zircon are detected: (I) gradual bending of the crystal lattice without subgrain boundaries, (II) local gradual bending of the lattice with formation of semicircular subgrain boundaries, and (III) strain-free subgrains separated by subgrain boundaries. The difference is controlled by strain rate and differential stress. Activation of energetically preferable slip systems is facilitated by decoupling from matrix and/or by soft host mineral.
