<b>EBSD-Based Calibration of Differential Stress From Experimentally Deformed Black Hills

This dataset contains raw EBSD data files from two experimentally deformed Black Hills Quartzite samples with 0.5 μm and 1.0 μm step sizes, used in Johnson et al. (2025) published in the Journal of Geophysical Research. It includes MATLAB scripts to reconstruct grains from the EBSD data and calculate grain boundary fractal dimension (GB FD), along with a MATLAB script to plot Figure 6 comparing piezometers in Johnson et al. (2025). An Excel file includes Table 1 and Table 2 from Johnson et al. (2025), and a summary Excel file contains all the data used in Johnson et al. (2025).

Use Cases

• Calibrating differential stress from experimentally deformed quartzite using grain boundary fractal dimension
• Reconstructing grains from raw EBSD data for microstructure analysis
• Comparing grain size distributions between 0.5 μm এবং 1.0 μm step size EBSD scans
• Validating the perimeter-area fractal dimension method for paleopiezometry

Strengths

• Raw EBSD data from two samples enables direct microstructure examination
• MATLAB scripts provided for grain reconstruction এবং GB FD calculation enhance reproducibility
• Direct linkage to published results in Johnson et al. (2025) provides context
• Includes both high-resolution (0.5 μm) এবং standard (1.0 μm) step size data for comparison

Limitations

• Dataset size (611.7 MB) may require substantial storage এবং bandwidth
• Requires MATLAB for running provided scripts, may limit users without access
• EBSD data processing requires specialized software (e.g., MTEX) বা expertise
• No column-level documentation in Excel files; field semantics must be inferred

Provenance

Source

Data originates from experimental work published in a peer-reviewed journal (Johnson et al., 2025).

Collection Method

Data collected via electron-backscattered diffraction (EBSD) on experimentally deformed quartzite samples, with grain reconstruction এবং fractal dimension calculation performed in MATLAB.

Time Range

Experimental data collection likely occurred prior to 2025 publication.

Geography

Samples are from Black Hills Quartzite, a geological formation in the United States.
