Neutron characterisation of iron meteorite fragments from Monturaqui and Wabar impactites

Abstract: Meteorite impacts are one of the most significant processes modifying planetary surfaces, where materials (e.g., rocks, sand, meteorite fragments…) are subjected to temperature of several thousands of Kelvin and pressures of several GPa. These collisions cause irreversible geological changes in the target material, forming shock-metamorphosed rocks called impactites. Impactites from iron meteorites are partially melted, glassy materials containing fragments of the original meteorite—under the form of Fe-Ni spherules—scattered in the glass matrix. We propose to investigate metallic spherules from Monturaqui (Chile) and Wabar (Saudi Arabia) impactites, in order to characterise, by Rietveld refinement of the diffraction pattern, the average composition and microstructure of the alloy (as residual strain, domain size of the crystallographic grains, and defects density).
