Renne, R. P., H. P. Schwarcz, M. R. Kleindienst,
G. R. Osinski, and J. J. Donovan, 2010, Age of the
Dakhleh impact event and implications for Middle
Stone Age archeology in the Western Desert of Egypt.
Earth and Planetary Science Letters. vol. 29, No. 1-4,
pp. 201–206

In part the abstract reads:

"Dakhleh Glass comprises a suite of chemically distinctive
and heterogeneous glassy rocks that occur over an area of
ca. 400 km2 in and around the Dakhleh Oasis in central
western Egypt."


"The age of the impact event is determined from a
compositionally filtered subset of the data that yield an
isochron age of 145 ± 19 ka."

Dakhleh Oasis, Egypt
