Fig. 6From: Postseismic fluid discharge chemically recorded in altered pseudotachylyte discovered from an ancient megasplay fault: an example from the Nobeoka Thrust in the Shimanto accretionary complex, SW JapanEPMA element mapping images of a Al, b K, c Mg, and d Si. Analyzed area is shown in Fig. 5b. Al and K show flow texture and residual phyllosilicate particles within matrix, while the Mg distribution is complementary. Red-colored parts of the Si map show the distribution of residual quartz grainsBack to article page
