Fig. 2: FIB slice images and space weathering rim of metal particles embedded in lunar soil impact glass.
From: Impact-induced ultra-high melting point oldhamite discovered in Chang’E-6 lunar soil
a FIB slice position; b STEM image of the FIB area; c, d TEM DF and BF images of the interface between iron particles and glass (The Oldh means Oldhamite; orange DF and BF represent the imaging in dark field and bright field modes); e HAADF image of the iron particle area containing space weathering rim (The orange SW layer and the curve represent weathered rims); f, g Vesicles, magnified image, and FFT image of the space weathering rim on the surface of iron (The orange line marks the boundary between the metal phase and the Pt coating).
