The dataset contains the electron backscattered diffraction (EBSD) filtered data acquired on samples collected on cores from IODP Hole U1473A. A suite of 102 samples in gabbroic lithologies was analyzed through 116 EBSD maps of variable area width, generally 1-2 cm², and 3-3.5 cm² in coarse-grained samples. The scanning resolution was chosen as a function of the average minimum grain size of each analyzed sample and varies from 2.5 µm to 30 µm (average resolution: 10 µm). Raw pixel data was filtered with the Channel 5 analysis suite from HKL Technology (Oxford Instruments) and consists in a noise reduction followed by a wild spikes extrapolation (level 6).
