“…Raman peak characteristics are comparable to terrestrial standards from Nasdala et al 72 showing distinct trends in position and FWHM values in relation with the amount of damage induced by metamictization processes. This observation agrees well with other studies of zircon in the Martian breccia: Hu et al 57 and Roszjar et al 74 observed similar zircon spectra, either well crystalline or deeply damaged. Specifically, they confirmed the presence of highly heterogeneous zircon displaying both crystalline and amorphous domains in a single grain, similar to the BSE images in Figure 8C,D, which are not related to impact texture.…”

Using continuous-wave and time-resolved Raman spectroscopy, we investigate and characterize the mineralogy of the NWA 7533 meteorite, a unique Martian regolith breccia. This meteorite is a crucial sample, giving a rare access to the formation and evolution of the primitive Martian crust, with crystallization processes beginning up to $4.4 Ga years ago. We provide an overview of Raman spectra for feldspar, plagioclase, pyroxene, olivine, apatite, merrillite, zircon, pyrite, and various Fe-Cr-Ti oxides like magnetite, hematite, ilmenite, and rutile. Most analytical points are paired with previous electron microprobe

“…Laser‐induced photoluminescence (PL) has never been applied to plagioclase with the aim to highlight shock effects, but has proven useful in providing information on lattice damage in other phases (e.g., Roszjar et al. ; Lenz et al. ).…”

Shock amorphization of plagioclase, from partial to complete, has been used to evaluate the degree of shock in meteorites. Important information on the shock amplitude can be derived from the measurement of the refractive index in plagioclase, either from mineral separates or in petrographic thin sections. However, this technique is timeconsuming, and associated sample preparations are considered destructive and are not always possible for precious and rare meteorite samples. In addition, plagioclase amorphization is commonly inhomogeneous at the sample scale and a statistically meaningful number of grains must be considered. Here, we apply several nondestructive spectroscopic techniques, such as Raman spectroscopy, photoluminescence, and cathodoluminescence, to plagioclase experimentally shocked at 28 GPa, and thus in the transition regime between crystalline plagioclase and fully amorphous material. Most of the plagioclase was transformed into diaplectic glass at 28 GPa, yet some grains exhibit heterogeneously distributed crystalline domains. This confirms that intrinsic and extrinsic factors lead to local variations in the intensity of the shock pressure within individual plagioclase crystals of homogeneous composition. The amorphization of plagioclase can qualitatively (and potentially also quantitatively) be investigated by spectroscopic techniques, highlighting such local variations in the shock efficiency.
