Figure 4
This microscopic image displays a textured surface characterized by an array of mineral fragments. Various shapes and sizes of materials are visible, predominantly appearing in shades of grey with some sections exhibiting blue tones. Significant spatial variation exists among the fragments, which may include angular and rounded particles, suggesting a heterogeneous composition. A scale bar at the bottom indicates a measurement of 100 micrometres. The detailed structure reveals intricate surface features, contributing to a complex visual pattern of the sample being examined. The image captures the nuanced relationship between the different materials while showcasing the intricacies of their arrangement.SEM image of a brittle cryo-fractured filament piece made of Alfaohm with highlighted graphite particles coloured blue by hand
