Although I am too busy to go to the library, a quick
check of the references on the Wabar impact crater
show a number of citations that discuss the impact
melts created by this impact. Possibly, one of the
below reference might help.

The four that seem most promising are:

See, T. H., F. Hoerz, and A. V. Murali-A-V (1988) Two
types of impact melt from the Wabar Crater, Saudi Arabia.

Science Conference. no. 19, Part 3; pp. 1053-1054. Lunar
and Planetary Science Conference. Houston, TX.

and Wabar, Arabia. Zentralblatt fuer Mineralogie,

A possibly promising article is:
