Figure 8

Backscattered electron images showing dislocation microstructures of olivine. Dislocations are shown as white dots and lines. (A) Homogeneous distribution of dislocations in olivine in the large-grained area (sample 372). E-type LPOs are observed from sample 372. (B) Magnified view of Figure 8A. Straight dislocations are observed. (C) Homogeneous distribution of dislocations in olivine in the large-grained area (sample 373). A combination of A- and B-type LPOs are observed. (D) Magnified view of Figure 8C. (E) Dislocation of olivine in the medium-grained area in mylonite (sample 380). (F) Magnified view of Figure 8E. (G) Heterogeneous distribution of dislocations in olivine in the small-grained area in mylonite (sample 380). (H) Four-grain junctions (yellow arrows) found in the small-grained area in mylonite (sample 379).
