Figure 10.
The image displays two close-up microscopic views of mineral samples. The upper section (a) features a mix of red and green mineral fragments, including angular pieces and some irregular shapes. There is a scale bar measuring twenty millimetres located at the bottom left corner. The lower section (b) presents a similar arrangement of mineral pieces, predominantly red, with some white inclusions. The scale bar remains consistent at twenty millimetres in the same position as in the upper image. The backgrounds of both images contain a more uniform texture, enhancing the visibility of the mineral fragments.Uranyl fluorescence images of the cut surface of a concrete prism made of reactive andesite containing 5.5 kg/m3 Na2Oeq and stored at 10°C for (a) 26 weeks and (b) 62 weeks (Kitagawa et al., 2023)
