説明
<jats:p><jats:bold>Abstract—</jats:bold> We have analyzed the size, shape, composition, and spatial distribution of 6 kg of layered tektite fragments excavated from a 3 m × 3 m area near the town of Ban Huai Sai in northeast Thailand. Our analysis suggests that these fragments represent a single homogeneous mass that underwent fragmentation far in the past and has undergone little disturbance since its deposition. We have also studied the stratigraphic occurrence of layered tektites exposed <jats:italic>in situ</jats:italic> near the town of Ban Huai Om. Tektites were found along a disconformable paleo‐erosion surface covered by recent aeolian sand, similar to other occurrences throughout Southeast Asia. This stratigraphic relationship provides little chronostratigraphic information and, thus, does not support a stratigraphic “age paradox” for the Australasian tektites. The present‐day surface density of layered tektites in this area is 2 to 20 g/m<jats:sup>2</jats:sup>.</jats:p>
