Fig. 6From: Hf-W dating of zircon in mesosiderite with high-pressure sintered standardScanning electron microscope image of zircon grains extracted from mesosiderite “Asuka 882,023.” Bars show 20µm or 50 µm. Based on the image, inclusion-free homogeneous regions suitable for NanoSIMS analysis were located by eyes and shown by red squaresBack to article page
