A–C, D–F, and G–I are hand specimen, optical microscopic, and back-scattered electron images, respectively. A, D, and G (sample no. B20) show textures in metasedimentary strata. They contain apatite and lack visible alteration. B, E, and H (sample no. B13) illustrate textures of the contact zone and a close interaction between the intrusive and the metasedimentary strata. C, F, and I (sample no. B23) show textures of the intrusive unit, which shows no alteration. Sample depths are provided in Supplementary Table S1.
