Well stated Jeff, one of the few times recently that we agree on issues.

There is the "fever" to coin new terminology for this apparent "unique"
stone (NWA 7034), which in essence is a breccia, but may not be a
"basaltic breccia". Everyone should calm down and wait until some
further research information comes out in the forthcoming LPSC Meeting
and the longer term research results that will come to light further on
downstream.

For those folks eager to get some time in on this naming issue, have fun
with it, some of you are, patience to the rest of you.
