“…The ChemCam identified gypsum, a water-bearing non-metallic calcium sulphate mineral (CaSO 4 • 2H 2 O), as veins on the rim of Endeavour Crater, Mars as veins [55]. Therefore to know the environment on Mars that is responsible for gypsum, Rai et al [56] studied gypsums samples from varied terrestrial environments. Textural types have been analyzed for their inter-sample comparison using LIBS data combined with multivariate statistical analysis methods, which can be correlated with the data of ChemCam LIBS sensitivity to the water content, and in particular hydration levels of calcium, sulfates can discern between anhydrite (CaSO4), bassanite, CaSO 4 • 1/2H 2 O, and gypsum very quickly, and it has demonstrated in the study.…”

Laser-induced breakdown spectroscopy (LIBS) is emerging as an analytical tool for investigating geological materials. The unique abilities of this technique proven its potential in the area of geology. Detection of light elements, portability for in-field analysis, spot detection, and no sample preparation are some features that make this technique appropriate for the study of geological materials. The application of the LIBS technique has been tremendously developed in recent years. In this report, results obtained from previous and most recent studies regarding the investigation of geological materials LIBS technique are reviewed. Firstly, we introduce investigations that report the advancement in LIBS instrumentation, its applications, especially in the area of gemology and the extraterrestrial/planetary exploration have been reviewed. Investigation of gemstones by LIBS technique is not widely reviewed in the past as compared to LIBS application in planetary exploration or other geological applications. It is anticipated that for the classification of gemstones samples, huge data set is appropriate and to analyze this data set, multivariate/chemometric methods will be useful. Recent advancement of LIBS instrumentation for the study of meteorites, depth penetration in Martian rocks and its regolith proved the feasibility of LIBS used as robotic vehicles in the Martian environment. Keywords: LIBS, gemstone, geological samples, extra-terrestrial.

“…At a suitable gate delay, the signature of molecular emissions is also expected to occurwith LIBS Our experimental results reveal that the concentration of Fe and O in the present sample arean appreciable amounts, i.e., ≅ 28% and ≅ 34%, respectively. The high concentration of these elements may result in the formation of molecular bands in the recorded spectra [24,25]. Thus, we have tried to identify the molecular band of FeO in the LIBS spectra of theDergaon meteorite.…”

Meteorites are the recoverable portions of asteroids that reach the surface of the Earth. Meteorites are rare extraterrestrial objects studied extensively to improve our understanding of planetary evolution. In this work, we used calibration-free laser-induced breakdown spectroscopy (CF-LIBS) to evaluate the quantitative elemental and molecular analyses of the Dergaon meteorite, a H 4-5 chondrite fall sample from Assam, India. Spectral signatures of H, N, O, Na, Mg, Al, Si, P, K, Ca, Ti, Cr, Mn, Fe, Co, Ni, andIrweredetected. Along with the atomic emission, this work reports the molecular emission from FeO molecules. The concentration of the measured elements obtained using CF-LIBS is in close agreement with earlier reports. The elements H, N, and O and their concentrations are estimated by using CF-LIBS for the first time. This study applies laser spectroscopy to establish the presence of Ni, Cr, Co, and Ir in meteorites. The elemental analysis forms the basis for the establishment of the potential molecular composition of the Dergaon meteorite. Moreover, the elemental analysis approach bodes well for in-situ analyses of extraterrestrial objects including applications in planetary rover missions.
