    Various permineralized plant stems from Carboniferous, Permian, and Triassic test localities around the world have been studied by imaging and analytical tools. Microscopic techniques, hot cathodoluminescence spectroscopy, X-ray diffraction and electron microprobe analyses served to characterize miscellaneous mineral matter present. Two main permineralization pathways were distinguished: fluvial (alluvial) one and different one controlled by volcanism. The fluvial silicification of plant stems proceeded in seasonally variable climate, i.e. these fossils are significant palaeoenvironmental indicators independently on their palaeobotanic evaluation.
