The interplanetary space contains particles of cosmic dust that come from the interstellar medium, or that are the product of the erosion of Asteroids, Meteoroids and Comets. The particles that reach the Earth s surface are called micrometeorites. Micrometeorites participate in the erosion processes of the Earth s surface and, therefore, are studied in order to have a better understanding of the evolution of our planet and the Solar System. A new research program was initiated in 2016 in the Department of Physics of PUC-Rio with the objectives of 1) finding an experimental means to simulate the impacts of micrometeorites with the terrestrial surface, and 2) analyzing the physical-chemical changes caused by the impacts on terrestrial minerals. In order to simulate the impact of micrometeorites the Laser Ablation technique was employed, which allowed us to make energy depositions at controlled rates in certain areas of the samples. For this work, we chose samples of the most abundant silicates found in the earth s crust, such as jadeite, quartz and feldspar. The ablation of the silicates was carried out in two medium: the sample in air, and the sample in H2O. The main analytical technique used was Raman spectroscopy. In addition, optical microscopy and profilometry were used. About 500 Raman spectra were obtained, and several bands for each sample and in each medium, before and after ablation, were statistically analyzed. The energetic and morphological analysis of the laser impacts showed that the technique of laser ablation is reasonably good to simulate the impacts of micrometeorites with the terrestrial crust. The analysis of the Raman spectra showed that after the ablation, in air as well as in deionized H2O, all three silicates presented modifications in the intensity, width and position of the center of several of their main bands. It was found that, when there were modifications, the behavior was the same for all silicates: a shift of the center of de bands to smaller wavelengths. The results of the analysis by Raman spectroscopy are encouraging to use this technique in the characterization and interpretation of the spectral and structural changes in the terrestrial surface after the impact of micrometeorites. This work, to the best of our knowledge, has never been done before. Its perspective is to give continuity to this line of research, incrementing the amount of experiments by laser ablation and extending the analysis of the irradiated samples to other characterization techniques that complement Raman spectroscopy (UV-Vis-NIR spectroscopy, FTIR, …). Also, in future studies, more complex samples will be studied, where organic material will be added to the already studied silicates.
