Disgrifiad

Electron backscatter diffraction (EBSD) data were acquired from two thin sections of quartz veins which deformed in metapelite at greenschist facies conditions, and metabasalt at epidote-blueschist facies conditions.  The dynamically recrystalised quartz grain size, quantified using the EBSD data, forms the basis of our estimates of the strength of oceanic crust during subduction at greenschist to epidote-blueschist facies conditions.

The data were collected using a Zeiss Sigma HD Field Emission Gun Analytical Scanning Electron Microscope at the Electron Microbeam facility in the School of Earth and Ocean Sciences at Cardiff University.

The dataset provided here includes two Channel 5 text files, one for each thin section. The data may be interpreted using the freely available MTEX software, available on GitHub (https://mtex-toolbox.github.io/). The file "inland_Makimine_quartz.ctf " contains the data for the greenschist facies stress estimate, while NMR_quartz_in_amphibolite.ctf contains the data for the epidote-blueschist facies stress estimate.

In the textfiles the data are arranged in the following columns, from left to right:  Mineral phase, X Position, Y Position, number of Kikuchi bands, 3 columns of Euler rotations, the mean angular distortion, band contrast, band slope.
