Hi All
I have some Ebay auctions ending tonight. Several still at $1.00.

http://search.ebay.com/_W0QQsassZmeteorfinder

I updated my last NWA Bessy meteorite sale page. Still has lots of goodies remain unsold. All are 20% off.

I also have some extra copies of a of book I recently offered for sale. This is a
special price with an original list of over $125. I am offering them here for only $75 each plus shipping. This is close to 40% off the original price. I cannot replace these books at this price. Only two copies available.
The book has a who's who of top scientists as the authors. See details below.


Meteorites - Flux with Time and Impact Effects

Author/Editor: Edited by G. J. H. McCall, M.M. Grady and R. Hutchison
and D. Rothery
Publication date: 25 August 1998
Binding: Hardback
Pages: 272

The Earth is bombarded constantly by material from space. Evidence of
this bombardment comes both from craters that may form prominent features
in the landscape, and samples of the impactors curated as meteorites. Since
the impact of extraterrestrial material on Earth has the potential to be of more
than local significance, and can lead to effects traceable in both the
geological and biological record, it is important to obtain an accurate picture
of the extent
of bombardment. Several techniques have been used to derive estimates for the
flux of extraterrestrial material to the Earth, both now and throughout the
geological record. The methods used to assess meteorite fluxes and impact
effects are diverse and involve scientists from different communities
(geologists, geochemists, biologists and astronomers).The volume commences with
description of the meteorite flux with time, covering both small bodies
(including strewn fields and the problem of 'pairing' of meteorites) and large
bodies capable of producing craters and cryptoexplosion features. The discussion
includes the different ways in which the flux has been determined
(from observational astronomy, meteorite collection statistics and theoretical
calculations). Following on this comes the documentation of impacts in the
geological record and their effects on the environment, focusing specifically on
the Cretaceous-Tertiary (K/T) boundary mass extinction event. Although the
geophysical and geochemical evidence for a large impact at the end of the
Cretaceous period is quite clear, the possible environmental consequences of an
impact are still a matter of active debate, and the fossil record is by no means
an unambiguous record of the mass extinction so frequently reported.
