Until samples from the Martian surface are successfully brought to Earth, meteorites represent the only opportunity to perform laboratory analyses on Martian material. Microimaging spectroscopy of the Martian meteorite suite provides a valuable means to better understand infrared data collected remotely from the Martian surface. This rapid and non-destructive method surveys compositional and textural relationships within and between meteorites samples. We expand upon existing documentation of the spectral variability of the Martian meteorites by presenting a publicly accessible dataset of over 1.2 million 1.0-2.5 \u00b5m spectra at 250 \u00b5m/pixel scale, from 144 imaged faces of 78 pieces of 54 distinctly named Martian meteorites. These meteorites include 2 chassignites, 6 nakhlites, 43 shergottites, 2 polymict breccias and 1 orthopyroxenite. Analysis of the spectral diversity results in the definition of 17 spectral classes on the basis of 1) color properties of the samples in false color with channels identified at spectrally significant wavelengths for mafic mineralogy, 2) a 3-step classification process comprised of a two-step unconstrained (orthogonal) Sequential Maximum Angle Convex Cone (SMACC) endmember extraction, Spectral Angle Mapping (SAM), and consolidation of the endmembers and their classified spectra into mineralogically significant groups, 3) band center position of the pyroxene 2 \u00b5m absorption, and 4) distribution and abundance of hydration/hydroxylation absorptions at 1.4 and 1.9 \u00b5m. Careful inspection of the spectra and processed data revealed compositional textures that are invisible to the naked eye, rare spectral phases, two distinct populations of high-calcium pyroxenes, and evidence of secondary aqueous alteration.

This data accompanies \"Characterizing Hydrated Sulfates and Altered Phases in Jezero Crater Fan and Floor Geologic Units with SHERLOC on Mars 2020\".

Included are .csv files containing data from:

(1) results of peak fitting of SHERLOC spectra. These are stored in separate files by geologic unit: 'SHERLOC_PeakFit_CraterFloor.csv', 'SHERLOC_PeakFit_FanFront.csv', 'SHERLOC_PeakFit_UpperFan.csv'. In each file, the data is organized by the measurement sol, target name, and the scan type. The 'scan type' column is labeled by \"#1_#2_#3\" whereby #1 is the scan type HDR or detail, #2 is the laser pulses per point used to acquire the spectrum, and #3 is the scan number conducted on each target at each sol. The peak positions, peak intensities, full-width at half-maximum (FWHM), and SNR for the mineral and hydration peaks, as well as peak area for the hydration peaks are recorded.

(2) spectral data for anhydrite and kieserite measured in this work, in 'LabSpectra_anhydrite_kieserite.csv'.

(3) SuperCam LIBS-derived data for the H peak area, in 'SuperCam_H_PeakArea.csv'.

(4) SuperCam near-infrared data for the band depth of the 1900 nm absorption, in 'SuperCam_1900BandDepth.csv'.

Here we used a prototype instrument to image serpentinized igneous rocks and carbonate-rich travertine deposits to evaluate performance, relative to traditional techniques: XRD (mineralogical analysis of bulk powders with no texture preservation) and SEM/EDS (analysis of phases and textures using chemical data from polished thin sections). VSWIR microimaging spectroscopy is ideal for identifying spatially coherent rare phases, below XRD detection limits. The progress of alteration can also be inferred from spectral parameters and may correspond to phases that are amorphous in XRD. However, VSWIR microimaging spectroscopy can sometimes be challenging with analyses of very dark materials (reflectance <0.05) and mineral mixtures occurring at a spatial scales multiple factors below the pixel size. Abundances derived from linear unmixing typically agree with those from XRD and EDS within ~10%.", "doi": "10.22002/D1.222", "publisher": "CaltechDATA", "publication_date": "2017-03-13" } ]
