Online NASA Translation of Soviet Tektite Paper

Online NASA Translation of Soviet Tektite Paper

While looking for some other information, I came across
the below, interesting online, Public Domain paper about
tektites that was translated from the Soviet literature.

Vorobyev, G. G. 1973, What do you know About Tektites.
Translation of "Chto Vy Znayete o Tektitakh?" Moscow,
"Nauka" Press, 1966, 112 pages. NASA techdoc no. 19730020646
(Report no. ASA TT F-15,052) National Areonautics and
Space Administration, Washington DC, August 1, 1973.

https://archive.org/details/nasa_techdoc_19730020646

The abstract reads:

“The discovery and geographical distribution of tektites is
presented and analyzed in this popular account of tektites.
Uses made of tektites by ancient and present-day peoples
are examined as possibly indicative of tektite origins.
The various theories on the origin of tektites are weighed.
Field collection of tektites in South Czechoslovakia is
described. The rise and waning and revival of interest in
tektites is traced. Tektite strewnfields are delineated and
related to possible impact of asteroids or lunar material
on the earth.”

New Geology About Non-Impact Circular Features

New Geology About Non-Impact Circular Features - Polygonal
faults in chalk

An interesting paper by Dr. B. J. Tewksbury an others
has been published online in Geology. It talks about a
well exposed system of polygonal faults that are
exposed in outcropping chalks in the Western Desert
of Egypt at Latitude 27.289982 N, Longitude 28.491490 E.
There polygonal fault systems form numerous circular
structures displaying shallow inward dips. Although they
would not confuse expert interpreters of aerial imagery,
amateur fans of Google Earth might confuse them with
an impact crater field. They do show that ther are a
variety of non-impact processes that can create circular
structures.

The paper is:

Tewksbury, B. J., H. P. Hogan, S. A. Kattenhorn,
C. J. Mehrtens, and E. A. Tarabees, 2014, Polygonal
