[meteorite-list] Shatter Cone

[Dan Wray]

Larry,

Based on your findings I pulled out my slice of Black Onaping, it is indeed 
magnetic in certain spots.  This is a revelation.  I had never thought to 
check my impact breccias for magnetic susceptibility.  My Grey Onaping does 
not react the same way.
