Post-Perovskite phase: Here's the latest, greatest update from the geophysics community. The argument is that the D" discontinuity near the mantle edge is because of a phase change to the Mg SiO3 perovskite into a postperovskite phase (behind closed doors the argument is being made that it may be monoclinic or some other unrelated to perovskite phase eek!) If you're curious, see Murakami's Science paper of 2004. The latest, greatest data is showing that with a temperature gradient under pressure, you get a pure ppv phase and without one you get a mixed pv-ppv phase. I'm so excited to see how this will turn out! Nothing ever happens in geophysics!

Anyway, I read your journal and thought hmmm, maybe a handful of people at the most would be able to understand what you wrote. Don't you think it is kind of strange posting things like that on a porn site? I'm not trying to offend you but not everyone on this site is a scientist or an engineer.
Are ya going for your masters? I want to go back and get mine but I'm far too busy for that. I'm sure it will happen one of these days though.
Adios Amiga.
