Muong Nong tektites or layered tektite glass is not commonly found in any of the tektite strewnfield except the Indochinite strewnfield. In all the others this layered glass is found only as a very rare piece. But, in the younger Indochinite impact region this glass is found as both large and small masses. It is chemically dry though not as dry as splash form tektite glass an is therefore not possibly of any other origin than that by asteroid or comet impact.
Muong Nong may represent some form of impact melt sheet glass. Large masses present the appearance of having formed by the repeated flowing of thin layers of molten glass. Building layered by layer a thick sheet which is much more bubbly and much less homogeneous than splash form glass while still being chemically similar to that of the aerodynamically formed specimens.
All of our Muong Nong specimens are from the Darryl Futrell Collections of Tektites. Specimens with catalog numbers beginning with the letters “FT” are hand numbered specimens from his collection.
