[meteorite-list] The Origin of Chondrules and Chondrites - Part 1 of 3

[Gerald Flaherty]

Thought this "older email on the subject from Bernd might be interesting to 
some. It's one of those few files I save. P.S. I took the advice and 
purchased it but I'm still baffled or is it befuddled?!

> The origin of chondrules and chondrites, by Derek Sears.
> Cambridge University Press, 2004, 209 pp.
> $110.00, hardcover (ISBN 0-521-83603-4).

> Few would disagree with Derek Sears' claim that chondrites are the most 
> studied rocks
> in the solar system and the least understood. To help remedy this, Sears 
> has written a
> monograph, which is profusely illustrated with black-and--white images, 
> diagrams, and
> sketches, that reviews the properties and proposed origins of chondrules 
> and chondrites.
> He carefully guides the reader through the wealth of chemical and isotopic 
> data on chondrules
> and chondrites, provides an excellent account of the theories of chondrule 
> origins, and offers
> a coherent, though very controversial, model for their origin.
> The first two chapters provide a historical overview of chondrite research 
> and classification and
> a concise guide to the asteroids, their role as meteorite parent bodies, 
> and the effects of impacts
> in forming regolith and impact melts. This is followed by a brief review 
> of the chemical and oxygen
> isotopic compositions of the various groups of chondrites and their ages. 
> Sears then identifies what
> he considers to be the most important questions about chondrites: how did 
> the chondrules form and
> how were Fe,Ni metal and silicate fractionated from one another? The last 
> half of the book focuses
> on the chemical, physical, and isotopic properties of chondrules that bear 
> on these two questions
> and the various mechanisms that have been proposed to form chondrules.
