Data for: The organic geochemistry of “Kolm”, a unique analogue for the understanding of molecular changes after significant uranium irradiation

(Right) White light reflection image showing serrated vitrinite-like organic matter of different grey intensities. White reflections are from pyrite. (Left) UV light illumination demonstrates that the OM in the intercalated clay layers is still reactive thus showing weak fluorescence.(右侧) 为白光反射图像，展示了不同灰度等级的锯齿状类镜质组有机质（vitrinite-like organic matter），其中白色反射区域来自黄铁矿（pyrite）。(左侧) 为紫外光照射图像，可见夹层黏土层中的有机质仍具有反应活性，故而呈现出较弱的荧光。
