主 题：lunar glasses glass fibers amorphous rims micrometeorite impacts gentle impact environment
摘 要：Lunar glasses with different origins act as snapshots of their formation processes,providing a rich archive of the Moon’s formation and ***,we reveal diverse glasses from Chang’E-5(CE-5) lunar regolith,and clarify their physical origins of liquid quenching,vapor deposition and irradiation damage *** series of quenched glasses,including rotation-featured particles,vesicular agglutinates and adhered melts,record multiple-scale impact *** micro-impact products,like micron-to nano-scale glass droplets or craters,highlight that the regolith is heavily reworked by frequent micrometeorite *** from Apollo samples,the indigenous ultra-elongated glass fibers drawn from viscous melts and the widespread ultra-thin deposited amorphous rims without nanophase iron particles both indicate a relatively gentle impact environment at the CE-5 landing *** clarification of multitype CE-5 glasses also provides a catalogue of diverse lunar glasses,meaning that more of the Moon’ s mysteries,recorded in glasses,could be deciphered in future.
