Muong Nong tektites or layered tektite glass is not commonly found in any of the tektite strewnfield except the Indochinite strewnfield. Much of the Muong Nong material has been obtained from bomb craters in Eastern Laos. Based on the spatial distribution of Muong Nong-type tektite sites and the chemical characteristics of the objects, Schnetzler has suggested that the source region is in a limited area near the Thailand/Laos border. More recently, Dass and Glass have investigated the occurrence of mineral inclusions in the Muong Nong-type Australasian tektites and suggested that the Muong Nong-type tektites from Muong Phin, Laos came from a site closer to the source crater than do other Muong Nong-type tektites. The geographic variation of 10Be contents in Australasian tektites may also provide clues to the location of the source crater. 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.
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.Most Muong Nong specimens have chips on them. Each specimen detail page will list if there are chips on the specimen. The listed price for each specimen takes into account any chipping that the specimen may have.
