The color of the Rock can be little different (depends on your device and my camera)

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.
