From: 3D X-ray tomographic analysis reveals how coesite is preserved in Muong Nong-type tektites
Backscattered electron images of coesite-bearing frothy inclusions from sample MN20 showing textural features comparable to MP26 (a,b). Note the presence of gaps in the relict quartz rim (a) and the outward increasing size of the vesicle constituting the froth layer. Coesite-bearing frothy inclusions from an impact glass of Pantasma crater (sample P20-3), Nicaragua, showing textural features similar to those described for coesite-bearing frothy inclusions of MN tektites (c,d).
