[meteoriteplaya at comcast.net]

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.
