OT: More Wrongway GPS Navigation

OT: More Wrongway GPS Navigation

Dear Friends,
Back in April of 2011, there was a discussion of 
the need to use common sense in using GPS for
navigation in “"Death by GPS" in desert” at:
http://six.pairlist.net/pipermail/meteorite-list/2011-April/075724.html

Recently, there was an example of the need to
be careful about navigating with GPS in:

impact crater? (Dnieper-Donets Basin)

I thought, 'nice cross section... which unexposed crater 
made the news?' I'd love to see some chip samples from 
near the center."

Klett, T. R., C. J. Schenk, R. R. Charpentier, M. E.  Brownfield, 
J. K. Pitman, R. M. Pollastro, T. A. Cook, and M. E. Tennyson,

of the Dnieper–Donets Basin Province and Pripyat Basin 
Province, Russia, Ukraine, and Belarus, 2010. World 
Petroleum Resources Project Fact Sheet 2011-3051.
United States Geological Survey, Reston, Virginia.

Looking at figure 1 of the above fact sheet, the Dnieper-
Donets Basin that is just less than 1400 kilometers long 
and about 200 to less than 100 kilometers wide. Its general
morphology alone argues against it being of impact origin.
The cross-section of Dnieper–Donets Basin shown in 
figure 2 of the above fact sheet is typical of numerous 
basins of terrestrial, non-impact origin. There nothing 
about it that argues for any sort of impact origin. 

The geology of the Dnieper-Donets Basin is well known
and very well documented. It is an intracratonic rift basin 
that opened in Late Devonian (middle Frasnian) as the 
result of the clockwise rotation of the Ukrainian shield
relative to other parts of the Russian craton. It is
characterized by linear bounding faults, substantial 
crustal thinning, syn-rift volcanic activity and other 
geological features that are typical of rift basins (Chekunov 
et al. 1992, 1993; Ilchenko 1996, Starostenko et al. 1999; 
Stephenson et al. 2006; Ulmishek 2001; Wilson and 
Lyashkevich 1996). There exists more than enough 
interpretations and data to demonstrate that the Dnieper-
Donets Basin cannot be any sort of impact crater.

Age of Lonar Crater, India, Revised to 656 ± 81 ka

Age of Lonar Crater, India, Revised to 656 ± 81 ka

Dear Friends,

A recent paper published online in "Geology" formally 
revises the age of the Lonar Crater in India to 656 ± 81 ka

Jourdan, F., F. Moynier, C. Koeberl, and S. Eroglu, in press, 
40Ar/39Ar age of the Lonar crater and consequence for the
geochronology of planetary impacts. Geology, published 
online on 24 May 2011 as doi:10.1130/G31888.1
http://geology.gsapubs.org/content/early/2011/05/19/G31888.1.abstract

Jourdan, F. , F. Moynier, C. Koeberl, 2010, First 40Ar/39Ar

Lunar and Planetary Science Conference (2010), Abstract
no. 1661.
http://www.lpi.usra.edu/meetings/lpsc2010/pdf/1661.pdf

“Conclusions: We propose a new impact age at 656 ±
81 ka for the Lonar crater. This age is based on 40Ar/39Ar 
analyses of several samples combined in a statistically 
robust global inverse isochron (MSWD =1.29; P =0.12). 
This age is in accordance with the preservation state of 
the crater.”
