Fig. 2From: Hf-W dating of zircon in mesosiderite with high-pressure sintered standardOptical micrographs of synthetic zircon (Std-A and Std-B) by high-pressure experiments. They were embedded in epoxy resin and the surface was given by mirror finish. The small spots are 20 µm pits carved by LA-ICPMS. Dotted red squares show the areas observed by SEM–EDS in Fig. 3Back to article page
