[meteorite-list] SF Chronicle - Dismissed 'rock' a meteorite after all

[Alan Rubin]

I just read the article in the Chronicle and send this e-mail to the writer:


David:
    I just read your article and have a correction to make.  I understand 
that it is easy to confuse unfamiliar terms, and it probably makes no 
difference to the vast majority of your readers.  However, what I said was 
that "chondrules" are igneous objects that solidified from molten spherules 
in the solar nebula.  Chondrites are rocks that contain the chondrules. 
Chondrites are not igneous rocks.  Igneous rocks have been melted; 
chondrites have not.  If the chondrites had been melted, the chondrules 
inside of them would have been melted also and would have disappeared.  For 
meteorite researchers this is a fundamental point.  Chondrites are unmelted, 
agglomerated rocks that preserve inclusions from the earliest history of the 
solar system.  These inclusions include the chondrules.
