Hi All,
Here is the classification for the meteorite that was recovered from
the June 1998 Casa Grande fireball. I just want to say thanks to
several people. Rob Matson and Marc Fries for the Doppler radar work.
Rob Ward who provided eyewitness information to aid in the radar work.
Alan Rubin for doing the classification. Here are Alan's results.
H5, S1, W0
olivine Fa 17.9±0.3 (n=16)
low-Ca pyroxene Fs16.0±0.2 Wo1.5±0.2 (n=19)
Ca-pyx Fs5.2 Wo47.0 (n=1)
The chondrite has a few plagioclase grains up to 25 µm across.
I hope to post a few more pictures on my webpage soon.
Sonny
