Sections based on tomography are typically used to illustrate
'subducting' plates.   But what,  really,  is the justification for

I'm doing research on petrogenesis on Cretaceous Alkaline Rocks and it is
quite difficult to get hold of some recent PTX diagrams concerning rocks
like syenite, nepheline-syenite, nephelinite, alkali basalts without having
to wade through piles of German publications. Does anyone ...

what is it with NASA ? why do they do this to themselves? I wonder why they
are still in business.
why did they lie to the public and why are they editing the so called *raw*
images? what purpose does it serve? I asked myself a few time to trust

Pb presumably only comes from decay of U238 which was formed

Dr. Wilton Krogman literally "wrote the book" on anatomy, worked on
cases with law enforcement and not just in the ivy-covered halls of
