Hi List,
My two cents worth: Tektites are blasted into space and then
return. Horizontal flow, blast , ejection or whatever, would not a
tektite make, at least in the classical sense.

Where is the dividing line between impactite and
tektite? I'd like to hear what others may understand,
but my impression is that it fundamentally hinges on
distance the glassy material is ejected from the
crater. Material found only in and immediately around
the source crater is impactite. Stuff blasted tens to
hundreds of km or more crosses the definitional
boundary into "tektites".
If this is the criterion, LDG was already home free in
my book insofar as the known strewn field has a long
axis of at least 150 km, so even if there was a
now-erosionally removed crater at one end of the
strewn field proper, some of the glass would've
already required over 100 km ejection distance.
