Hi Frank,
I share Martin's appreciation for your input with regard to this subject
especially in light of evidence (proof - NASA called it) of a previously
large flowing river across Mars revealed on 2/2/98 by NASA in pictures
taken by the Global Surveyor. My first thought was that any brecciations,
by their nature, must have been caused by abrupt displacement, if you will,
of solid water converted rapidly to liquid water due to impact or
collision that separated it from the parent. But I'm not sure if
the speed at which this may have occured in combination with the
heat generated is consistent with the amount of mafic minerals vs. the
amount of phyllosilicates with regard to different brecciations.
What do you think? Regards, jj.
