Date of data collection (single date, range, approximate date) June 2022 to April 2023 5. Geographic location of data collection (where was data collected?): Advanced Photon Source, beamline 6-BM-B, Argonne National laboratory, IL, USA, as well as Characterization Facility | College of Science and Engineering, University of Minnesota - Twin Cities, MN, USA. 6. Information about funding sources that supported the collection of the data: Use of the Advanced Photon Source, Argonne National Laboratory, was supported by the U.S. Department of Energy, Office of Science, Office of Basic Energy Sciences, under Contract No. DE-AC02-06CH11357. Use of the 6-BM-B beamline was supported by COMPRES, the Consortium for Materials Properties Research in Earth Sciences, under NSF Cooperative Agreement EAR-1661511. Parts of this work were carried out in the Characterization Facility, University of Minnesota, which receives partial support from the NSF through the MRSEC (Award Number DMR-2011401) and the NNCI (Award Number ECCS-2025124) programs. Portions of this work were performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344. LLNL-JRNL-2000685 7. Overview of the data (abstract): This DRUM entry is associated with the manuscript on Nonlinear viscoelasticity of the upper mantle to be submitted to JGR: Solid Earth in March 2025. It contains the raw diffraction data and radiographs collected during the deformation-DIA experiments presented in this manuscript. It also contains raw electron-backscatter diffraction data collected on the sample materials before and after deformation and annotated vector graphics files of decorated dislocations in select samples. Finally, it also contains a spreadsheet containing the required metadata to go along with these data. -------------------------- SHARING/ACCESS INFORMATION -------------------------- 1.

File List A. Filename: Metadata sheets.xlsx (also available in non-proprietary format as 'Metadata sheets.ods') Short description: Excel sheet containing metadata for analysis of mechanical and EBSD data as well as dislocation densities obtained from images of decorated dislocations B. Filename: Raw experiment data.zip Short description: compressed directory containing subfolders San_591, San_597, San_625, San_626, San_628, San_630, and San_637, each containing the raw output files of the software at APS beamline 6-BM-B for the experiment of the subfolder name. These outputs include the diffraction data (.med files), radiographs (.tif files), the metadata for the diffraction data and radiographs including timestamps and apparatus data (.label files) where San_###.label is the original output file and San_###b is a modified output file with more consistent file name and path string formatting to facilitate data processing. Miscellaneous output files are also included for completeness but were not used in the data processing. Each subfolder also contains the alumina calibration .med file used for each experiment as listed in file 'Metadata sheets.xlsx'. C. Filename: EBSD data.zip Short description: EBSD data.zip is a compressed file directory containing subfolders for each hotpressed starting material (PT1616 and PT1242) and all post-experiment samples (San 591 through San 637). Each subfolder contains the .cpr and .crc files of the processed (_clean) as well as the unprocessed EBSD data. Exceptions to this rule are that only the processed data is available of the EBSD data from the center of hotpress PT1242, included as 'PT1242 center_clean.ctf', and that the data for 'SAN_630 top PT1616_clean' was subsetted to avoid a poorly indexed area in the EBSD map, which was performed in MTEX thus an MTEX ebsd variable named 'SAN_630 top PT1616_clean subset ebsd.mat' is included to illustrate the subsetted area in subfolder San_630. D. Filename: Decorated dislocation images.zip Short description: Compressed folder directory containing subfolders San 591, San 597, San 625, San 626, San 628, San 630, and San 637, each containing backscatter electron images (.tif files) of decorated dislocations in the top or bottom (i.e., 'San 591 top' or 'San 591 bot') of the sample stack in a DDIA assembly and annoted versions of the images as vector graphics files (.svg files) in which individual dislocations are counted by dots and the area over which dislocations were counted is highlighted in blue. Further information associated with these images can be found in 'Metadata sheets.xlsx'. -------------------------- METHODOLOGICAL INFORMATION -------------------------- 1.
