OTHER TEKTITES (AND IMPACTITES)

Sometimes the boundaries between tektite and impactite become blurred. A tektite is effectively the material thrown away from the impact site, with impactites actually being at, or close to, the impact site. There is no set distance from a crater that an object must be before it crosses over from impactite to tektite. Notably, true tektites are not usually found close to the source crater. The decision to call an object a tektite or impactite is largely a personal choice. My favoured means of differentiation is that a tektite should show a degree shape formation (which may, or may not be, secondarily altered by atmospheric re-entry or impact with the ground). I consider amorphous rocks to be impactites. As such Moung Nong tektites could be considered impactites (even though, prior to landing they may have had a shape - this is a grey area). Spheres, dumbells, tear drops, etc. are true tektites.

Other tektites/impactites include:

Darwin Glass

Zhamanshinite

Libyan Desert Glass

K-T Impactite

I intend to expand this section when I have the time!
