Guten Abend Stefan, Hello List,

" I'm considering to buy: The Origin of Chondrules and
  Chondrites by Derek Sears, any recommendation?"


Book Review: MAPS 40-4, 2005 April, pp. 655-656:

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.
