Data for: Quantitative Evaluation of Shock Metamorphism in Clinopyroxene Using in situ X-ray Diffraction Measurement of Lattice Strain
Bibliographic record
Abstract
X-ray diffraction (XRD) patterns for the study “Quantitative Evaluation of Shock Metamorphism in Clinopyroxene Using in situ X-ray Diffraction Measurement of Lattice Strain.” XRD patterns were collected from select targets in three Martian meteorites (Allan Hills (ALHA) 77005, Nakhla, and Zagami), as well as from three sets of experimentally shocked terrestrial clinopyroxene (cpx) samples (A0, A1, A2, B0, B3, and HEXP6). A0 and B0 are both unshocked, with A0 being a monomineralic cpx sample and B0 being a gabbro from the Bushveld Igneous Complex (BIC). A1 and A2 are monomineralic cpx samples that were shocked at 8 GPa and 22 GPa, respectively, with a light gas gun at the University of Kent. B3 is BIC gabbro from the shocked to 50 GPa by a flat plate accelerator (FPA) for another study (Meyer et al. 2011. Meteoritics & Planetary Sciences, 46: 701-718). HEXP6 is monomineralic diopside shocked to 20 GPa by FPA at the Experimental Impact Laboratory at the National Aeronautics and Space Administration Johnson Space Centre. XRD patterns for all samples were collected using an in situ micro X-ray diffractometer equipped with a Co kα source and an area detector from targets on intact unpowdered samples. Data was collected using General Area Detector Diffraction System (GADDS) software. They are not powder patterns. For more information regarding in situ micro XRD please see Flemming (2007. Canadian Journal of Earth Sciences, 44: 1333-1346). Data for each target is presented in four files: two .gfrm files, one .tif file, and one .raw file. The .gfrm files are two overlapping frames of 2-D XRD patterns that can be processed with the relevant software (e.g., GADDS, DIFFRACplus.EVA). The .tif file is a visual representation of the .gfrm frames. The .raw file is an integration of both .gfrm files into a traditional intensity versus 2θ plot and can be processed with the relevant software (e.g., DIFFRACplus.EVA). The .raw files can be used for mineral identification, while the .gfrm files can be used to isolate individual XRD peaks for peak width measurements. This work measured peak widths in 2θ for single peaks that matched exclusively cpx. Peak widths were measured as integral breadth. Lists of peaks measured in 2θ for each target for the study is in the attached guide.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
