Spectral reflectance analysis of type 3 carbonaceous chondrites and search for their asteroidal parent bodies

Non-differentiated asteroids are among the most primitive objects in our Solar System, having escaped intense heating mechanisms. To help us understand information contained reflectance spectra measured on asteroids, we analyzed meteorites laboratory. We present an in-depth analysis of a large set spectra: 23 CV3, 15 CO3, 4 CR2 and 31 Unequilibrated Ordinary Chondrites (UOCs). Each samples has well characterized thermal history . Variations observed between within each chondrite group. UOCs systematically exhibit deeper absorption features, distinguishing them from carbonaceous chondrites. The presented this study easily distinguished type 3 chondrites by exhibiting 1 {\mu}m band at lower wavelengths. CV CO comparable mineralogical compositions can, therefore, not be solely based their spectral features. In case chondrites, depth increases with increasing metamorphic grade, while visual slopes. By comparing various end member able to suggest several possible genetic links studied
