Comparison of planetary evolution processes studying cosmic thin section sets of NASA and NIPR
Abstract
Thin sections of samples from the moon and from Antarctic meteorites represent a huge 'raw material' for education in studying thermal evolutionary (inner) and metamorphic (mainly impact, outer) processes on planetary and asteroidal bodies with different sizes. This size range embraces source bodies from the parent bodies of meteorites to the moon and Mars. Characteristics of both inner processes (equilibration, diffusion, grain-size distribution changes, melting and differentiation, etc.) and outer processes (impact effects in breccia formation) are left on the texture of fragments from these bodies. In our report we summarize almost two years of comparison studies on thin section sets of NASA lunar samples and NIPR Antarctic meteorites.
