From: 3D X-ray tomographic analysis reveals how coesite is preserved in Muong Nong-type tektites
Results of 3D analysis of textural parameters for different volumes of MP26 analysed at different voxel resolutions. The sphericity of both free and froth vesicles (blue circles) and of coesite-bearing frothy inclusions (orange circles) is plotted versus the diameter of the sphere with equivalent volume; note that the froth vesicles and free vesicles are distinguished based on their different trends and that the division between the two trends (blue dashed lines) is drawn by eye (a). Vesicle size distribution (VSD) frequency histogram (x axis in logarithmic scale) (b) and cumulative plot indicating the vesicle number density (VND) of each vesicle size class (c).
