DEFORMATION OF ZIRCONS IN ZONES OF SEISMOGENIC SLIP. PRELIMINARY RESULTS OF NUMERICAL EXPERIMENTS

Abstract

We present preliminary results of a numerical study of the behavior of zircon grains in a shear band filled with a model material with the properties of granite. Calculations performed in a flat formulation showed that the destruction of the zircon grain occurs much later than the fault filler material. The possibility of «survival» of a zircon grain in a band of width H is demonstrated when it is shifted by Δx to an average deformation of Δx/H ~ 0.2–0.4.
