EBSD and EDS dataset for: Dislocation creep of glaucophane in mafic blueschists during subduction: Weighted Burgers vector analysis from the Catalina Schist (California, USA)

Electron backscattered diffraction (EBSD) and energy-dispersive X-ray spectroscopy (EDS) data collected from Garnet Blueschist block sample, a polymetamorphic metabasaltic lawsonite blueschist emplaced in the melange of the Lawsonite Blueschist Unit of the Catalina Schist subduction complex on Pimu'nga (Santa Catalina Island, CA, USA; 33°22ʹN 118°28ʹW). A structurally oriented thin section (perpendicular to foliation, parallel to lineation, X-Z plane in section) was prepared from the sample. Mineral assemblage is glaucophane (55%) + lawsonite (15%) + phengite (<10%) + garnet (5%) + quartz (10%) + titanite (<5%) with minor apatite.
