There is an IMCA member, Roman Jirasek, (www.meteoritelables.com) also
on this list that has a wealth of information about Sudbury, Clearwater,
Brent, Wanapitei and other Canadian impact sites. He also lives up
there, and has some incredible impactite samples for sale as well. I
purchased some slabs of the Sudbury and Brent impact breccia's and
glasses from him that have better visual appeal than most meteorites...

Hi,
I'm an amateur geologist and the
naming and classification of rocks I
find very confusing. I enjoy a good
technical read. Anyone care to offer
suggestions on the "bible" of
petrology (is that the right word? ) I
reckon there might be some people on
the list that would appreciate some
good advice in this area as well as
me.

FWIW if you are learning C programming
its Kernighan & Ritchie, The C
Programming Language, but I bet thats
not much help to anyone here. :)

The other question thats rattling
round in my head is why there are so
few technical articles linking areas
like Sudbury, Clearwater and Bushveld
to meteorite impacts.

Bernd mentioned a while ago that it
took science centuries to accept that
rocks fell from the sky. Impact
induced mantle plumes seem to be the
"unpopular" model for these massive
mineralised areas. (see below)

Is there a nometeorites101 in geology
at uni where all first year geologists
get this idea pounded into them?
Sometimes, I think geologists should
make some new definitions.

regards to all in meteorite land

Mark & others,

This is totally absurd. Look up
"gabbro" if you can spell it. Then
write.

make up new definitions---)
